My name is Peter and I'm my computer seems doomed at the moment, which is why I've registered here in the increasing desperate hope of finding a solution. In order to rescue my PC from the clutches of the msa.exe bug I've decided to go straight to XP's registry editor and manually pull the plug on this damned trojan. To that end I'm hoping there's a listing somewhere in this forum that shows exactly which registry files to delete.
Anyway wish me luck. Failing this, it's reformatting the C drive
