After surfing on the net for a long time, don't you ever find that your computer's speed has really gone down? Or some stupid ads which are always popping up whenever you open your browser? Well, the reason for this is spyware is present in your PC. Spyware programs make money for their publishers by reporting your Internet travels and sending you advertisements. Some also report your name, e-mail address, and other personal information. Spyware may continuosly irritate you with pop - ups from the sites they come from. They also slow down your computer. There are many Antispyware programs. The most popular are Ad - Aware SE and Spybot - Search and Destroy. I myself use these with another called Spyware Doctor making a total of 3 and get different results each time I scan. After using Firefox, I thought i'd compare the speed with IE. After using IE, I saw with Ad - Aware that there were 77 spyware files in the computer. I swear that I won't shift back to IE now! All of the above mentioned Antispyware programs are available on www.download.com There is also a new program Windows Antispyware by Microsoft. You can try that also.
