I, I have pretty much the same problem. I tried to run aswMBR, it produced this log:

22:57:24.093 The log file has been saved successfully to “\Ares\Inbox\aswMBR.txt”

Now, what leaves me with an headache is that, at the end, aswMBR enables the “FixMBR” button, and NOT the “Fix” button that I expected (as the rootkit appears to be a TDL4@MBR per the log).

Why, and what should I do? Go for the recovery console and try with FIXMBR?

Is it the secondary hard disk, the reason it is enabled FIxMBR and not Fix?

Enlighten me, please, 'coz i’m in the deep dark right now.
