Its amazing my pc is still functioning correctly. The intercheck monitor that comes with sophos antivirus runs in the background as a system service to be on gaurd at all times against viruses before they hit your pc. So I never thought to run a full system scan because I thought the intercheck monitor was sufficient.
That obviouly wasnt the case. I think Im going to switch to another vendor. But I hate norton and avg products so Ill probably try and find something else.
