While testing various anti-spyware utilities last year (find.pcworld.com/40211), I discovered that two otherwise top-notch spy catchers, Lavasoft’s Ad-aware and PepiMK Software’s Spybot Search & Destroy, weren’t particularly good at finding the keyloggers that I had running in stealth mode on my test PC. Two other programs — PestPatrol Inc.’s PestPatrol and Webroot’s Spy Sweeper — were better, though still hit-or-miss. No product found all of the keyloggers I had installed. And even when they did find one, seldom could they completely disable or remove it.
