RootkitRevealer
Download Sysinternals RootkitRevealer
RootkitRevealer assists in detection of rootkits on your system. The app works by doing two types of scans of system information. One at a user level and one at a lower operating system level. By comparing the results of the two scans, RootkitRevealer finds files and applications attempting to obscure themselves from detection. The software requires administrator level access to perform scans. This is pretty geeky stuff and requires a little digging to make sure you don't screw up your system as a result. It's like anti-spyware on steriods in terms of system defense. Assuming you know what you're doing, you can manually remove detected files. What's needed next is an application to effectively remove rootkits without wrecking your system as a result. [Windows 9x/2k/XP $0.00]
