one day i got a mass virus load, it shut down my antivirus and other applications so i had to do a reformat. After the reformat my harddrive seemed clean, but my concerns was my external HDD which was connected to my PC at the time the viruses arrived. However, i scanned it with Avast, Superantispyware, Spybot and Blacklight, only thing they found was an old GTA IV crack (but that was probably a false positive) I guess this isnt a lot of info but should i access my external? Or should i use more programs to scan it? (suggestions please) I dont want to reformat it since i got lots of stuff i dont want to lose. If its any help i had some Win32/heur on my main drive before i reformat it.
