A word of warning: Neither I nor sUBs are responsible for any damage you may have caused your machine. This tool is not a toy and not for everyday use.



Close all browser windows and refering to the picture above, drag CFScript into ComboFix.exe
Then post the resultant log & a fresh dds.txt log.


Combofix should never take more that 20 minutes including the reboot if malware is detected.
If it does, open Task Manager then Processes tab (press ctrl, alt and del at the same time) and end any processes of findstr, find, sed or swreg, then combofix should continue.
If that happened we want to know, and also what process you had to end.
