Spy Sweeper  Spyware has eclipsed viruses as the fastest growing online threat, infecting nearly 90% of Internet connected PCs. Spyware can infect your system in many different ways: visiting a spy-spreading web site, opening a spy-carrying email attachment, downloading a spy as part of another (often "free") software program, etc. Your privacy, and even your identity, is at high risk if you surf the Internet more than one hour a week, share your computer or use file-sharing programs like KaZaa.
