It seems my computes get infected while surfing a free movies site last week while I had Norton 360 activated on the machine. As soon as I clicked on the link the computer shut down and restarted by itself. After retstarting I ran a google search for smeothing, when I clicked on any of the search results it took me an entirely different advertisement page. Soon after that the machine started crashing and restarting on a perpetual basis. It will restart go to a blue screen, I think generally called BSOD, and then shut off and restart again. I can hardly read the whole message on the blue screen but it says something "disable bios memory options such as caching or shadowing". I tried to run Norton 360 scan in normal mode but could not, then did in Safe mode but nothing was found. I ran Malwarebytes in safe mode by storing in a usb drive and then running on the infected computer, which shows to find Trojan.Agent which was deleted and computer restarted by Malwarebytes scan but it would repeat the infected behavior again in normal mode - show the blue screen and shut off and restart again. When Malwarebytes is run again in safe mode, Trojan.Agent threat is detected again, but it would not go away even though I did quick scan about 5-6 times and full scan once and threat was removed everytime. I ran Kaspersky Malware removal and Norton Power Eraser also, but no threats were found. Please help!! I am not sure what to do... I am using window IE and windows 7 ultimate os 64 bit.
