I recently got a trojan on my pc, cleaned it out, but since then my zonealarm says that ism.exe is trying to access the net. i did a search for that and 2 files pop up:
ism.exe in c:\program files\ism
ISM.EXE-18A7F98C.PF in c:\windows\prefetch

is this a legit file and i should allow it access? im currently running yet another virus scan to be sure i got everything.

It looks like some bullshit man, but I'd wait for one of the computer techies to come in here to make sure.
