I think I have a trojan.
svchost.exe is consuming %25 cpu all the time, and my Microsoft Security Essentials reports a different virus every half an hour or so. From what I understand the trojan is downloading different viruses. MSE removes those but can't disable the real culprit.
I have tried a couple bootable scanners such as Kaspersky Rescue Disk, they seem to find the same ones found by MSE but with no further success, when I restart my pc svchost still uses %25 cpu and I get new virus alerts time to time.
My question is, I have a windows backup of my C drive (120gb single partition), if I delete the partition and format it and then restore from backup, is it a sure way to get rid of trojan, assuming it didn't attach itself to something in D drive (which is a seperate hdd) and I don't run it? I read some trojans reside in GUID tables and such, can this action get rid of them?
