I recently ran into a computer that had System Fix malware, but that may have let in some other nasties. The machine had a new style boot sector virus that I had not run into before. MalwareBytes found nothing, and neither did VIPRE Rescue or SuperAntispyware. I ran mbr.exe from gmer.net, and got the generic error when running about an I/O error when attempting to read the boot sector. This boot sector was infected heavily, but after clearing with fixboot & fixmbr, the system was done. The partition table must have been compromised/moved by the malware.

With this new, even nastier style bootkit, is there a standard procedure for removal? I know that hindsight is 20/20, but what could have I done differently? I ended up killing all the scrambled partition table data and formatting and re-installing.

can you please download and run TDSSKiller and post the resulting log. If it asks you to fix anything, then please DO NOT FIX ANYTHING.

Also post the logs from the scans you have done.

I'm looking for next time info... It's too late for this soldier, already been wiped and reloaded.
