I had something called rc overture, that every other spyware and av known for microsoft answers team (about 6 in all) couldnt remove or only removed part of (being super anti spyware...remove part).
The bug was making IE on-responsive.
I regularly run and have malwareytes free, stinger, nortons internet security. None of the guarded or removed it.
My pc guys suggested it would be good back up (and as it solved the issue, I thought why not)
Are you able to suggest seomthing else as good, or do you know of a reseller for hitman pro 64?
