My impression is that it is a 'false positive'.
I'd recommend reading through Pest Patrol's removal explanation, and checking to see if any of the files and registry entries that it lists actually exist on your machine.
After using Pest Patrol online scan, and reading some of the earlier threads here, I no longer recommend it to anyone.
while using PESTPATROL Online scan, it found:
in C:\Program Files\Common Files\Symantec Shared\ccregvfy.exe
When I click for more information, there is a removal explanation.
So, is this really a virus or pest patrol regular 'False positive' as usual?
-- If so.. should we be better warned for NOT using pest patrol?
