Spyware can be a nightmare for you if your computer is ever infected. Every computer user is constantly reminded about the dangers posed by spywares. The warnings are rather too commonplace that some of us tend to view then as exaggerated. The risk that spywares pose to your computer and your sensitive information is real.

The dangers range from a noticeable slow down in the processing speed of your computer to numerous and recurring pop-ups. It’s good for you to understand how a spyware behaves in a computer, so you’ll be able to tell when your computer has become infected. Most could be eliminated with a good anti-virus program under the guidance of a computer specialist. But our concern here is to understand what a spyware can do to your computer.

Once a spyware gains access into your computer, it begins to monitor your activities, as well as to collect information from your computer. This information is then transmitted to the spyware creator. It also floods your computer with loads of (mostly useless) advertisements. The presence of spywares in your computer often affects the processing speed and smooth functioning of your computer. But this is mostly a side effect of spywares and not their main purpose.

Some spyware programs are capable of deleting certain programs from your computer. They may delete some files or modify certain programs in order to get fully embedded in your system. This may include altering your anti-spyware programs that might eventually have helped in dislodging the malicious spyware with time! This is much the same way as the Acquired Immune Deficiency Syndrome (AIDS) starts by weakening the body’s self-defense mechanism.

There is also a particular type of spyware that alters a homepage or internet settings, resulting in massive amounts of pop-ups when one is browsing the web. This same type of spyware can also install numerous unwanted toolbars that may be difficult to remove.

Most spyware programs are very large in size. As a result, they take up a chunk of your computer’s memory space, leaving you unable to store certain programs and data. Moreover, these huge spyware programs often run in the background of your computer, using up processing speed, and thus making it extremely difficult for your system to run other useful programs smoothly. It’s like asking one PC to perform the tasks of say 20 PCs all at once!

Some spywares are also capable of hacking into your email account and collecting other personal information from your computer, and sending these as spam to countless other internet users, including the spyware creator. Let’s say you are shopping online and had typed in your credit card number, if you have a particularly bad spyware on your PC, it could collect those credit card details and send this to another computer.

Now, if you suspect that your computer may have been invaded by a malicious spyware, there’s no need to panic. If you already have an anti-virus installed on your computer, chances are that it includes an anti-spyware also. Run the anti-virus program. Most times that’s all it takes to remove some spywares.

But if that doesn’t work, then you may need a specialized anti-spyware removal tool. SpyZooka and Search &Destroy are among the best spyware removers. Some sites even have free anti-spyware tools which you can access by visiting their website. You could also enlist the services of a computer specialist if you are having problems getting your computer rid of malicious spywares.
