Impulse Update has virus in it
The lastest impulse Update is stopped by AVG 9, with the notice that it contains Win32/Zperm. AVG says it has had no notices of false positives on this virus or Stardock's site. Stardock needs to check its update server for this virus. If you let it run for a while, eventually the update bulls it's way through -- but I'm definitely going to run a full antivirus check tonight.
