A scan with Counterspy antispyware software indicated I have a commercial keylogger (XPCSpy Pro 2.25) on my PC. It is identified in C:\windows\prefetch\rundll32.exe-35BB92D4.PF. When I do a search the file identified by Counterspy exists in the specified location. What's confusing is that Ad-Aware, Spybot and SpySweeper do not identify this file as a keylogger. Any thoughts if this just a false positive??
