I also have the virus Trojan.Patched.Sirefef.B and BitDefender cannot quarantine it or delete it. When I run the scan it detects it but when i hit delete or quarantine it does nothing. The BitDefender screen just flashes and that's it. I also get a pop-up coming up at the bottom of the screen saying Svchost has been terminated because it has been deemed harmful so it seems to be doing some kind of blocking of the virus at least. Please help. I'd rather not take my PC into Geek Squad or wipe it and start fresh again. I did a google search and several sites gave info on manually removing it but files they said to remove were not there on my PC so this thing might mutate to have different file names. Not sure.
Thanks
