I was hit with some nasty virus/malware programs after coming home from college. There was one called Win 7 Security (I believe) that claimed my computer had been compromised. There was also one causing Ping.exe to use massive amounts of CPU time (which caused my computer to overheat). I got rid of the Win 7 Security program using Malwarebytes, but Ping.exe is still causing my computer to get really hot. I've also noticed that OfficeScan has gone crazy, telling me that it has deleted hundreds of viruses/malware (with names like TROJ_FAKEAV.DAM). How can I get rid of these problems once and for all? I've already got backups made just in case I have to start over. I'm running Windows 7 Home Premium 64 bit, Service Pack 1 on a laptop. Thanks for your time.
