Hi, been having this problem, in common with a lot of others it would seem from this forum.
Try to open up programs and an error message pops up saying 'application cannot be executed. the file --------- is infected. Do you want to activate your antivirus software now?' It does this for most programs excepting firfox and IE.
It seems like this is the place to come for help with such a problem, any help would be greatly appreciated.
