Anti-Spyware Software
Spyware programs can collect your personal information, install unwanted software, and change your computer's settings.
Installing anti-spyware software, like SpyBot Search & Destroy and Ad-Aware, is your best defense against spyware. These programs are used to find and eliminate known and emerging malicious programs and installations from your computer. Both are distributed free of charge by their developers.
We recommend that you use the two in conjunction with each other since one program can often catch spyware the other has overlooked.
