I tried doing this but when I drag and drop onto ComboFix, after the green bar has fully loaded, I get an error saying "Incompatible OS. ComboFix only works for Windows 2000 and XP". When I try running it in Safe Mode ComboFix does not run, I get an error saying that "c.bat is not a recognized internal or external file, program, or batch file".

Also, my AVG keeps alerting me to a virus called Win32/Virut, saying that it has been "Detected on open" for a variety of exe files.
