Ok so I've seem to have encountered probably the most difficult virus I've ever dealt with. I've followed the steps posted.


1. If everything else fails, I'll reformat and do DoD pass. I really wish I didn't have to.
2. I know I'm infected, logs and computer activity are pretty obvious.
3, 4. Done.
5. I'm using COMDO Free firewall.
6. Ran DeFogger and disabled emulation.
7. DDS log made.

8. GMER, weird thing about GMER is that it runs. But when it goes to display the log result in the listbox, it just hangs.

On another note, I was using Mozilla Firefox, then pages load slowly, rendering it useless. Tried uninstalling and reinstalling, same thing happened to Chrome, but Chrome doesn't work at all.
The only one unaffected seems to be Internet Explorer. Sometimes when I load a second tab it crashes, so I have to end process and restart.

UPDATE: I seem to have patched the MBR and but seems I still get.

Stealth MBR rootkit/Mebroot/Sinowal/TDL4 detector 0.4.2 by Gmer, http://www.gmer.net

kernel: MBR read successfully
user & kernel MBR OK
copy of MBR has been found in sector 9 !

After I fixed the mbr GMER seems to load, log made.
