I have a badly infected system with Nation Zoom. It doesn't appear that doing a system restore gets rid of it which suggests that all of the restore points may be infected. Has anyone of the EE's advisors found a successful way to completely rid a Windows 7 system of the virus? I've used all of the normal things...virus engine, malwarebytes, ccleaner etc. etc. I have not tried combo fix and tend to stay away from that until I have no other mechanism. Any ideas will be appreciated.
