Report PC infected by Trojans in Help, my PC is infected! Posted April 9, 2012 I've been talking to one of our researchers, and that file is a Windows System File. The reason scans are failing on that file could be due to filesystem damage and it could be due to physical damage to your hard drive. Follow the instructions at this link, and instead of loading Safe Mode load the Recovery Environment. Once you get into the Recovery Environment, you should see a screen like this: You'll want to click the link to load the Command Prompt. At the Command Prompt, type out chkdsk /R C: and it will check the filesystem for errors and check every sector on the hard drive for damage. Any repairs to the filesystem will be made automatically, and any bad sectors on your hard drive will be marked so that Windows won't try to write data in them.
