In a stupid moment I ran an exe which probaly contained malware... I saw MSE popping-up a warning that it detected 2 virus infections but before I had the chance to click "Remove it" the PC rebooted. It got into an endless loop of failing to repair startup issues. Within the log file, there was a bit of helpful information, “Boot Critical File d:\ci.dll Corrupted”. Searching Google I found it is probably a rootkit or something like that.
From the recovery console i tried following things:
I tried restoring to the previous system restore point.
I tried restoring the ci.dll with sfc /scanfile=d:\ci.dll but that fails with the message: "There is a system repair pending which requires reboot to complete..."
Then I tried restoring the master boot record using bootsect /nt60 d: but that failes with the message "... The update may be unreliable since volume could not be locked during the update: Access is denied".
I also tried running FRST64.Exe but that crashes during the scan: "Line 3294 (File F:/FRST64.exe) Error: Error in expression"
Anybody who can help resolve this or is the only way out a clean install and does that guarantee that the rootkit is removed?
