What is a Spyware?

Spyware is software that is capable of performing certain operations on your computer without your consent, such as displaying advertisements, collecting your personal information, or changing the configuration of your computer. Other types of unwanted software can alter your computer with results ranging from minor annoyances to causing your computer to slow down or crash. These programs have the ability to change your Web browser's home page or search page, or add additional components to your browser you may not need or want. These programs also make it very difficult for you to change your settings back to the way you originally had them. These types of unwanted programs are often labeled as spyware.

How can I tell that I have a spyware on my PC?

You may have spyware installed on your computer if:

* You see pop-up advertisements even when you're not on a website.
* Your homepage or your browser search settings have changed without your knowledge.
* You have a new toolbar in your browser that you didn't want, and find it difficult to get rid of.
* Your computer takes longer than usual to complete certain tasks.
* You experience a sudden rise in computer crashes.

How does a spyware get on my PC?

There are several ways spyware or other unwanted software can intrude your computer. A common trick is to covertly install the software during the installation of other software you want such as a music or video file sharing program. Whenever you are installing something on your computer, make sure you carefully read all disclosures, including the license agreement and privacy statement. Sometimes the inclusion of unwanted software in a given software installation is documented, but it may appear at the end of a license agreement or privacy statement.

How do I prevent from getting a spyware on my PC?

Here are few useful tips on how to avoid spyware infection:

* Use anti-spyware programs
* Keep your anti-spyware programs current by downloading updates.
* If using Microsoft's Internet Explorer, turn off its ability to run scripts without your permission.
* Prevent spyware from transmitting data off the system by using a firewall.
* Do not click on links within pop-ups. By clicking on a pop-up link you may install spyware on your computer. Close the popup with the "X" on the title bar, do not use the "close" link, if there are any available within the window.
* Do not download programs from websites you are not familiar with.
* Be careful of unexpected dialog boxes asking whether you want to perform an action. If you are not sure about the impact of the action, better click "NO" or close the dialog box by clicking the "X" icon in the title bar.
* Do not follow email links offering anti-spyware software. These links may actually install the spyware they claim to be keeping off your system.

That's it. Finding a good and reliable anti-spyware plays an important role in keeping your PC safe and healthy. A good place to start will be at download.com or browse through some reputable online magazine sites, such as PC Magazine and ultimately, you can also do a search on Google.
