mbr:sst found

I keep getting this virus found mbr:sst (rtk). I scanned with aswMBR and it didn’t show anything. I have attached the log file. I am stumped.

Hi,

aswMBR did show traces of posible MBR infections. First, let’s check your system.

Download DDS and save it to your Desktop from here:
http://download.bleepingcomputer.com/sUBs/dds.scr

Double click dds to run the tool.

* When done, DDS will open two (2) logs:
    1. DDS.txt
    2. Attach.txt

Save both reports to your desktop. DDS.txt and Attach.txt attach back to topic.
