WindowsDevCenter.com: Easily Purge Spyware, Adware, and Other Malware [Jun. 22, 2004]
Interesting reading. I dont know, but I also feel that browsing with firefox makes it a little safer still. Plus I like the small utility that comes with spybot that asks before a change to the registry is made by an application. Quite helpful. I cannot stand popups and hence, browsing on Windows is limited. Much safer to work in Linux.
