Wireless internet Terminologi

Wireless Internet Terminology, like many things in life, especially those that have anything to do with computers is filled with terminology. But like most things, once you learn a few of the basic terms, understanding will come quickly. So don't be confused get informed and to help clarify, I've put together a basic wireless "internet-to-english" guide to help you along.
IEEE - The Institute of Electrical and Electronics Engineers The IEEE is in charge of the wireless networking standard, as well as many other computer-related standards - including the Ethernet standard. They ensure that computer equipment made by different manufacturers can work together.
PCMCIA - Personal Computer Memory Card International Association Simply another standard for how to plug credit card size devices into a laptop computer to boost it's capabilities. It's been suggested by some that it should stand for "People Can't Memorize Computer Industry Acronyms". PCMCIA is a great way of adding wireless networking to your laptop as easily as inserting a disk.
PCI - Peripheral Component Interconnect Used to install devices like graphics cards and network devices inside your computer. You would be using a PCI, if you wanted to install a wireless card inside your computer.
802.11 Set by the IEEE, it's the current wireless networking standard. It helps ensure that wireless devices can communicate with one another or in other words - they are interoperable.
Interoperable Simply means that two different pieces of equipment have the ability to speak to each other or another way to put it - they are compatible. They can use them together because they were designed using the same standards. Because of the IEEE and the principle of interoperability, all wireless equipment you purchase should be compatible.
Driver Not a piece of golf equipment but computer software that informs a computer how to talk to devices that plug into it. Most wireless networking drivers come on a CD-ROM. You then download the drivers from the CD onto your computer.
Ethernet Currently, the most common way of connecting to a LAN or Local Area Network. Most wires connected to your computer today are ethernet and if you have a cable internet connection an ethernet wire is in all likely-hood, what is being used to connect to your modem.
USB - Universal Serial Bus A port used for connecting all sorts of devices to a computer, including keyboards, a mouse, printers, external hard-drives and basically anything else you can think of. If you don't have a laptop or want to open up your computer you can get a USB wireless device.
WEP - Wired Equivalent Privacy No longer used because in 2001 it was found to have security issues. As a result, it is now the old standard for encrypting wireless networks.
WPA - WiFi Protected Access The new standard for encrypting wireless networks. An upgrade of WEP to fix security issues. To avoid becoming vulnerable, a WPA encrypted network changes encryption methods often. In addition, if an attack is detected, it has the ability to shut itself down for thirty seconds.
PAN - Personal Area Network A network of devices connected together in one small area. A simple example of a PAN would be your computer, USB keyboard and mouse. Using a technology called Bluetooth, a PAN can be wireless.
LAN - Local Area Network Briefly mentioned above, LAN is a computer network that... generally speaking is confined to one building, such as a home or office. A wireless LAN is also known as a WLAN.
MAN - Metropolitan Area Network A network that covers a larger area, like a city or town. They are expensive but a wireless MAN has the capacity to spread Internet access across a wide area. Many college universities set-up a MAN to connect the entire campus.
WAN - Wide Area Network A network that covers or connects to more than one physical site. A simple example would be a business that has locations in different cities, states or countries and they need them each location connected on the same network. The Internet itself is a WAN... the biggest WAN in the world.
Mbps - Megabits Per Second Not to be confused with MBps, megabytes per second. Mbps is measurement of connection speed. There are eight megabits in a megabyte.
GHz - Gigahertz One gigahertz is one billion cycles per second... it's a measurement of frequency. If the term sounds familiar it's probably because it's also used to measure the processing speed of the CPU on your computer, which is also measured in gigahertz.
Linux A popular and growing alternative operating system to Windows. Linux is a less bulky, more efficient operating system in many ways than Windows and not to mention - it's free. Many servers run Linux for this reason. Computers running Linux can run many programs and connect to the Internet without needing Windows. Many wireless devices run Linux or are compatible with it.

Maintain your pc

Over time, even the most sophisticated, memory packed computer can begin to run slow if we don’t do something to prevent it. The reason why has less to do with how computers are made and how they age and more to do with the way we use them. You see, all of the daily tasks that we do on our PC from running programs to downloading and deleting software can make our computer sluggish.
To keep this from happening, you need to understand the reasons why your PC is getting slower and do something to keep your PC running at its best. You can do this through regular maintenance and PC performance optimization programs.
Before we discuss all of the things that could be affecting your PC’s performance, let’s talk a little about what symptoms a slow computer can have.
In addition to being excruciatingly slow when it comes to opening programs or finishing tasks, your PC may also experience data loss, unwanted shutdowns, Windows crashing and Windows hang up. All of these can be very annoying to deal with and are a sure sign that you need to optimize your PC and maintain it.
There are many reasons why your PC is getting slower and not performing quite the way it used to. Any one of them may be just the thing that is holding your PC back. In some cases, there is more than one culprit at work. But there are solutions to keep your computer from being affected by these nuisances, and we will talk about what you can do to maintain your PC and keep it running smoothly if it encounters any of these problems.
When you download and use programs on your PC, sometimes they are set up to start running as soon as you turn on your computer. These programs may be running in the background without you even knowing it and they use up precious memory needed for other tasks.
To see if you have any programs running in the background, press Ctrl + Alt + Delete at the same time.
A list of all of the currently running programs will appear in a pop up window. You can choose to stop the programs by highlighting the program and clicking “end task.” If you want to keep those programs from starting when you turn on your PC, change the individual settings for each program so that they will not automatically be turned on.
Memory is a computer component that allows it to do all of the various tasks that you require of it. When you start to do a task, a segment of memory is assigned to that task. If you don’t have enough memory and you try to do several tasks at once, you may run out of memory and not be able to perform any tasks properly. In order to optimize and maintain memory, you can use a Memory Optimizer program. This program changes the way that Windows manages memory so that you can use it more efficiently.
Your hard drive is like a huge filing cabinet containing all of the files that you need for your computer to perform properly. When you add programs, files are added to this data base. When you delete data or programs, files are removed. This process results in holes or empty spaces in your filing cabinet.
These holes make it harder for your computer to work because it continuously has to search for information over a larger distance and sometimes search for information that is completely out of order. To combat this, you need to defragment your hard drive. You can do this with your Windows system optimization tools or with a Registry Deffrager and Optimizer. These programs eliminate holes and arrange your files in a sensible order.
Just as your PC’s hard drive could be filed improperly, it can also be too full to work at its best. A good rule of thumb is to have at least 2MB to 3MB of space on your hard drive for your PC to function properly. To free up space, simply delete unused programs on the C: drive.
Maintaining your PC’s performance is vital if you want you computer to always complete tasks at its top speed. While Windows has some system tools to help you do this, they do not work on their own. You have to actually go and start the programs to optimize your computer. And they may not be enough. In this case, you may want to opt for optimization software such as PC Programs to help maintain your PC’s performance.

Notebook Buy Tips

This article describes the features one might be looking for while making a notebook purchase. The different sizes of notebooks, as well as mobile connectivity and multimedia capability are explained as well.


Why notebook became so popular? It has been estimated that notebook sales has increased an average of 20% per year in the United States alone. Among the many advantages it offers, portability is one of the main reason people end up making a purchase of it. However before any purchase is made, other features should be considered as well.

Notebook was first made available in the early eighties. Although much heavier and bulkier than today's notebooks, it had the unique portability feature that put this innovative product in a class by itself. Although not much of a commercial success then, it gave the computer industry a goal to pursue in manufacturing this item with better weight, size and performance ratio and making one of today's most wanted computer hardware.

Notebook size has got much smaller, however big enough to make one feel very comfortable in handling and operating computer related tasks. One can find it in sizes best categorized as: 1 - Tablet Pc has the size of paper tablet and weighs no more than 4 pounds; 2 - Ultra Portable is a little bigger than Tablet Pc and weighs around 4 pounds, no internal CD or DVD drive, display of 12 inches or smaller; 3 - Thin and Light is a mid-size notebook, 10-14" x 10", 1 to 1.5 thick, and weighs around 7 pounds, wireless network capability, 14-inch displays, combo CD-RW/DVD; 4 - Desktop replacement is the largest category of notebooks, more than 12 x 10" and weighs more than 7 pounds, 15-17 inches displays or larger, wireless network capability, combo CD-RW/DV.

Also an important feature one should look for is performance. Notebooks provide very close performance in comparison with traditional desktop computers, and should handle all computer related tasks with great ease. Whenever purchasing a notebook, make sure it has the latest cpu model, large ram memory and hard disk space. Notebook performance is directly related with cpu clock, ram memory and hard disk space. For these items, big is never enough.

Another feature one should look for is the dvd player. It can come in handy for entertainment purposes, enabling one to watch movies while traveling. Wireless connection is also a feature to look for in a notebook. Some notebooks feature an infrared port, which can be used to connect a mobile phone. Also there are other wireless technologies such as Bluetooth and Wi-Fi, which allows mobile phone, printers and PDA to be connected at certified public and private network. The ability to have a mobile connection is definitely a plus in today's connected world.

Expansion capability for notebooks can be done thru the use of plug-in pc cards. Although there is a new standard called ExpressCard, which is smaller and faster plug-in card that provides more features for multimedia tasks.

Notebooks have certainly become an item required for one's mobile computer related tasks, whether it is used for public, private, personal or professional purposes. Its portability and small size make an attractive all around computer hardware item. For those looking for mobile computer hardware, notebooks can certainly become a good solution at affordable prices.

Problems with Cell Phones

A cell phone, like any other electronic device, has its problems:
Generally, non-repairable internal corrosion of parts results if you get the phone wet or use wet hands to push the buttons. Consider a protective case. If the phone does get wet, be sure it is totally dry before you switch it on so you can try to avoid damaging internal parts.

Extreme heat in a car can damage the battery or the cell-phone electronics. Extreme cold may cause a momentary loss of the screen display.

Analog cell phones suffer from a problem known as "cloning." A phone is "cloned" when someone steals its ID numbers and is able to make fraudulent calls on the owner's account.
Here is how cloning occurs: When your phone makes a call, it transmits the ESN and MIN to the network at the beginning of the call. The MIN/ESN pair is a unique tag for your phone -- this is how the phone company knows who to bill for the call. When your phone transmits its MIN/ESN pair, it is possible for nefarious sorts to listen (with a scanner) and capture the pair. With the right equipment, it is fairly easy to modify another phone so that it contains your MIN/ESN pair, which allows the nefarious individual to make calls on your account.

Are You Safe from hackers

We don't use E-gold very often since most of our online business and customer sales are conducted through our online merchant account. However, we occasionally have someone who will request paying by E-gold so we keep an account there for this reason. Once a month or so we withdraw the funds and decided to do so yesterday. Imagine our dismay when we logged into our E-gold account yesterday and found our balance to be a big fat ZERO! We had checked the balance just a few days ago so we knew this was not correct. After investigating the history of the account, we found that a spend had been made to another e-gold account user WITHOUT our knowledge or authorization. We had been hacked!
Since we have up to date anti-virus and firewall software on our computer, we assumed we were safe. Not so! It seems this is not enough to keep away the hackers as the software does not prevent "Spyware" from being installed on your computer.
"Spyware" is software that gets onto your computer and literally "spies" on your activities. The spying can range from relatively harmless use of cookies tracking you across multiple websites... to extremely dangerous "keystroke loggers" which record passwords, credit cards, and other personal data. That data then gets relayed to the person who put the software on your computer.
Spyware gets on your computer in one of several different ways.
First, it rides along with software you download from the 'Net and install on your system.
Second, they come as email attachments (much like viruses) and automatically install themselves on your computer when you open the email message.
Third, hackers find an open port on your computer and use the "back door" to install basically anything they want.
And fourth, the more malicious types, like keystroke loggers, can even get installed by someone with direct physical access to your computer such as an employer, suspicious spouse, business competitor, or someone who wants to know exactly what you're doing.
So how do you protect yourself against these malicious hackers? You need a program that specifically scans your system for the tens-of-thousands of existing spyware programs along with the new ones appearing daily.
Below are two programs which specifically check for and remove spyware from your system:
"Spybot Search & Destroy" - www.safer-networking.org "Ad Aware" - www.lavasoft.de/software/adaware/
You may have spyware lurking on your computer right now so protect yourself today by downloading one of the above programs!
As a point of reference, we contacted E-gold and informed them that we had been hacked. We provided them with the account number of the person who received the funds and asked for a contact e-mail address on the person. E-gold informed us that they could not provide that information without a "court order" and that basically there was no way of getting the money back!
Take action today to protect yourself from this growing threat! The bottom line is: - Keep your anti-virus program current
- Install a firewall- Carefully screen software before installing it- Scan specifically for spyware weekly- Stay current on this growing threat.

HTML

"How to Profit by Learning the Foundation Language of the World Wide Web"

If you want to make money on the Internet in the course of your computer career, you’ll have an easier time if you know HTML. That’s true if you have your own web site, even if you use an HTML editor such as FrontPage 2000. It’s true if you want to work in Internet web site design or maintenance for a company. Even if you want to write Java programs, you will need to know how Java fits into a web site.
Even if you see into the future of the Net (which, amazingly, many people don’t) and see Virtual Reality on the not too far distant horizon, you will need to learn HyperText Markup Language before you can expect to start programming with Virtual Reality Markup Language (VRML).
HTML stands for hypertext markup language. It is actually a sub-language of SGML, Standard Generalized Markup Language. SGML actually goes back long before computers, beginning as a way for publishers to layout pages.
HTML is actually just instructions to your browser to display certain web page elements a certain way.
For instance, I’ve instructed this page’s HyperText Markup Language to display the second from top line as "H1," which means to display the page title in the largest typeface.
The magic of HyperText Markup Language lies in its ability to link documents or sections of documents together. The "hypertext" activates the Worldwide Web "hypertext protocol" (the "http" all web surfers know and love), so it sends your browser to the specified url.
It’s one of those things that we take for granted after we’ve been online for a few weeks, but is truly an amazing power. Through those simple links, it’s possible to access most of the data and information in the world.
It has been a basic part of email programs for years, and Word 2000 now has editing capability, so people are more and more going to be including links in email, file attachments, etc.
HyperText Markup Language is not going away.
It will expand and grow as computer bandwidth and capabilities and our needs and aspirations and imaginations grow. It will not disappear. It will continue as the foundation of DHTML (Dynamic HTML) and the previously mentioned VRML, and whatever it evolves into in the future.
It’s possible to surf the Net and do lots of neat stuff online without knowing any HTML – I did that for nearly 4 years. But if you want to make money online, you must learn it.
Fortunately, learning it for your computer career is easy.
There are classes and tutorials available offline and online. Also, many books and CD-ROMs.
Every web site you go to can teach you something. Simply click on View, and then Page Source. Right before your eyes, you’ll see that gorgeous web page disappear and turn into a mish mash of text with lots of <>s in it. Combine that with book learning and creating your own simple web sites, which you can do with any ASCII text editor (I just use Wordpad), and you’ll soon pick up all the basics.
You could actually use Wordpad to create all the web pages you’ll ever need, but that would be tedious. Editors such as Frontpage 2000, Hot Dog, Dreamweaver and Fusion were created to take the detail work out of it, leaving you free to apply your creativity to your web design.
My own advice, for what you think it’s worth. The worst thing Netscape ever did was introduce frames. I've glanced over the frames sections of my books, but I haven’t tried to learn those tags. I don’t consider learning frames any more necessary to writing it than learning legal jargon is necessary to for nonlawyers to speak English.
They can seem "neat" when they work right, but if you’re on the web for money, leave neat for kids.
Frames screw up the back button of browser, making it more difficult for your customers to navigate. This frustrates them and makes them less likely to buy from you. Frames screw up your standings in search engines, so small businesses depending on search engines to bring them targeted traffic should avoid frames.
Being bought out by America Online was the karmic punishment Netscape suffered for introducing frames. They meant well, but we all know what road is paved with good intentions.
To make up for it, they have introduced cascading style sheets to make beautiful web design easier. This is good, but don’t get carried away with it. Many people on the Net still have older versions of browsers and your carefully designed pages might look like a mess to them, even though you’re winning prizes on your computer job from people with new version browsers.
The best way around this for now, until you’re sure 99% of your target market is using a browser that supports cascading style sheets, is to design with tables.
In fact, the most difficult aspect of designing web sites is not learning it at all, it’s learning all the possible variations based on brand and version of browser. Netscape Navigator can interpret the same code a lot differently than Internet Explorer. The later versions (4.0 and above) of both programs will understand instructions that versions 1 – 3 of both browsers will not.
The previously mentioned DHTML really has two very different versions, one supported by Netscape and one supported by Microsoft.
If you are designing for a company intranet, this is not a problem because you’ll know exactly which browser everybody is using. Those of us on the Internet, however, face a situation only a little more organized than chaos.
The only real solution is to keep it simple.
Design for the lowest common browser version. Save the fancy stuff for the time when it’s common and no longer cutting edge.
Heck, I understand. Netscape is promoting 4.73 as I write, and I haven’t had time to download it yet myself, so I can’t expect everybody else to stay up to the minute either.
The day is soon coming when it will be as necessary for an "educated" person to know and use basic HyperText Markup Language as, up until a short time ago, especially in Europe, it was necessary for an "educated" person to know and use basic French.

Handphone Radiation

Just read an article on handphone radiation. Not too sure how accurate the information is, but why not prevent it whenever possible?This morning I heard a sad real story from my colleague. She told meone of her friend always miscarriage when the baby 2-3 months old for fewtimes continuously in few years time. The couple went to check with manydoctors and lastly one of the doctor check on the death baby and found out thebaby's body cells keeping die when baby growing up until he/she cannotbe survived. This is because her uterus has been affected by HANDPHONEradiotion. The doctor told she has no chance to get baby no matter howbecause the radiotion affected her uterus which the major portion ofher uterus cells already death, cannot carry healthy baby. All this becauseof she has been keeping her handphone in her working jacket which theposition just right to the uterus positon for few years time. Please beware andtake note the consequences is not worth.
Dearest family members, please do not overlook the handphone radiotionwhich will affect our health or body organs. Please put away yourhandphone when ever you don't need it much. Guys, please do not keep yourhandphone near to the kidney position and pants pocket as this will hurt andaffect your "production" if you plan to get baby.
The other doctor also advice another friend to keep away handphone toher new born baby to avoid radiotion to baby's brain and cells. Do not letthe baby or toddler play with the handphone for long time. Because thesmall young baby or toddler still very fragile and most probably they cannottake the radiotion.
Please remind yourself do not sleep together with your handphone or putnext to your bed. Keep away any other electronic goods (such as tvalso) which got radiotion away from your bedroom to reduce risk as we haveto sleep few hours a day in our bedroom at night. Do not think that youswitch off the TV it will be no radiotion actually it is still around in yourroom just not eyes visible. Even the small alarm clock not to be advised toput just next to your head while sleeping.
Care about yourself and people that you love.

The Wonderful Future Of Cell Phones

The popularity of the mobile phones is constantly on the rise like a snow ball. There are numerous reasons for that and they are well beyond mere communicating with each other.
The development of the cell phones and technology in the past decade along with social and cultural processes as well as sharp decrease in prices contributed to their phenomenon success.
Cell phones have long become a symbol of status as well as a fashion statement. Some manufacturers have started to produce special designed phones for women. Other models are designed with interchangeable facades to cater for the youngsters. A lot of young people are transferring their instant-messaging habits to their cell phones.
The integration of so many different functionalities and technologies into the cell phones is more impressive and beneficial than the all-in-one office devices that integrated a scanner, a copier, a fax and a printer into a single compact space saving multifunctional machine.
The current generation of G-2.5 technology as well as the very near future G-3 units that are starting to emerge right now will carry in it so many functions which are mind blowing. These new Cell phones are going to be a multimedia center, a mobile office, a navigation device GPS (Global Positioning system), a computer with fast Internet access, a text messenger, a high resolution camera and video, a watch, a calculator, a PDA, an MP3 music player, TV and a Wallet! Yes, we will be able to pay with it for things we today pay with coins like vending soda or coffee machines as well as for parking space, trains and buses tickets etc’. It has become our “Swiss Army Knife”...
In Israel they used the cell phone to send SMS message and approval for one dollar donation payment for needy children. I guess that in the future it will be a legitimate tool for voting in contests and may be even in Elections.
Writing in the Wall Street Journal, an executive for a wireless company noted that “in Slovakia, people are using mobile phones to remotely switch on the heat before they return home,” and in Norway, “1.5 million people can confirm their tax returns” using cell phone short text messaging services. Paramedics use camera phones to send ahead to hospitals pictures of the incoming injuries; “in Britain, it is now commonplace for wireless technology to allow companies to remotely access meters or gather diagnostic information.” Construction workers on-site can use cell phones to send pictures to contractors off-site. Combined with the individual use of cell phones—to make appointments, locate a friend, check voicemail messages, or simply to check in at work—cell phones offer peoplean unknown level of convenience. (Source: The New Atlantis – Article by Christine Rosen).
Other interesting applications are providing a locating service of your friends, or in other words if one of your friends is very close to where you are right now an SMS massage can alert you of this fact.
Cell phones and Dating Services
Several companies now offer a way to flirt and meet people anonymously. These services offer cell-to-cell texting and PC-to-cell texting. (Text-messaging phones also can receive messages sent over the Internet from a PC.) Companies including UPOC (Universal Point of Contact) and SMS.ac allow users to fill out a profile as they would at any dating service (some dating sites are dabbling with texting) and then search for an ideal match. Profiles can include photos and can be accessed either with a picture-enabled cell phone or through a PC. Say you want to meet a 20- to 30-year-old man in Kentucky who is interested in hiking. Do a search and three names pop up. You can send one a text message without ever exposing your phone number
Cell phones as safety device
One of the main reasons the cell phones have become so wide spread nowadays is that besides convenience it is perceived as a security and safety aid, Parents provide their children with mobile phones in order to track their whereabouts, to make sure they arrived safely to their destinations, to give them a mobile phone to report in real time when in any sort of trouble. Many women feel much safer in the street knowing they can call for help when in need.

Antispyware Or Spyware?

Spyware has become the most prominent computer security problem. How do you choose a good spyware removal tool? Beware of antispyware software which installs spyware/adware to your computer.
Spyware is a hidden software program. It is often used to monitor the browsing and shopping habits of computer users. Spyware can also be a remote control program that steals confidential banking and personal information.
Spyware has quickly become the most prominent internet security problem. According to the National Cyber Security Alliance, spyware infects more than 90% of home PCs. Recent survey shows that spyware is also sneaking into the network of corporate computers.
Spyware is often coupled with free downloads, such as free music, game and software downloads. Spyware may slow down computer, hijack homepage and create uncontrolled pop-up advertisements. Some spyware programs can remain unnoticed, secretly gathering information from the computer. Once installed, spyware is difficult to remove without the help of dedicated antispyware software.
Due to the rise of spyware activity, antispyware programs are in great demand these days. But are these spyware removal tools the same? Do they provide the security consumers need?
There are many reports that some antispyware programs installed their own spyware and adware to the computer. One consumer was quoted saying: “It’s a rip-off. I downloaded the free trial of an antispyware program, only to find out that it added its own adware to my computer.” Other consumers have complained that the antispyware program they use cannot detect all spyware programs. Some even slow down the computer and create pop-up advertisements.
There are a few good antispyware programs in the market today. On the other hand, dozens of spyware removal programs are blacklisted by consumers. Beware of spyware removal tools that are heavily promoted by e-mail campaigns. Never run any free downloads and free scans from unknown software publishers. Their programs may as well be spyware programs themselves. Read independent product reviews from renowned computer magazines or reputable sources. Spending some extra time in research can save you a lot of hassles in the long run.

Adware Removal should be Treated as a Seriously Major Priority

Adware removal is actually one of the most important aspects of keeping your computer running safely,securely and free from all outside intrusions. There are many people who think that adware and spyware does not indeed cause a great deal to worry about, this could not be further from the truth. The plain fact is that anything that infiltrates the inner workings of your computer must without fail be treated with the upmost distrust and caution.
Adware or spyware by its very nature will mainly be placed on a computer for reasons that are clearly financial. Nine times out of ten this is for tracking purposes in order to give the big companies as much consumer data as possible. They use it in order to gain information regarding your consumer activities and in what ways you carry out your online activities. At the other end of the scale there are those darker entities that have a far more sinister purpose and it is these folk that we truly need to be protected from and keep as far away from our personal computers as possible.
If you wondered just how these nasty adware parasites manage to infiltrate the inner sanctum or your computer then you may be surprised to learn that you yourself were probably the one that invited them in the first place. These hidden programs that are the plague of the internet community actually hide themselves in what most of us think to be some very innocent software's. From instant messengers to free software downloads you can be assured that you are downloading a little more than you first intended to invite.
One of the biggest sources of unwanted scumware are the numerous music download sites that are springing up all over the internet. Does anyone actually wonder why these folk are so kind and so willing to give away such a vast amount of free music programs and software's? Data is worth money and there are plenty of corporations in existence who are more than willing to purchase your data and dig to the inner most soul of your activities.
No matter if you suspect that you have been infected or not it is absolutely vital the regular system scanning is carried out. The cool thing is you do not even have to pay for such scans. Download a scan for free and if you are in the clear you will not have paid anything at all for the service. If however you are infected then you can rest assured that paying a small amount for computer cleansing by far outweighs the risks of having your computer carry a spy who is both watching,recording and submitting your private information for the bad guys to use.
As has been pointed out computer adware / spyware can have some extremely nasty purposes. Don't ignore the possible implications and ensure that you at least get a scan. For those of you who are extremely security conscious why not go all the way and purchase a full blown adware software protector, this way you will never need worry again. Be safe, Not sorry.
