I already replied to you with instructions here.

These are example entries from a FRST log explaining what is most likely going on with this VAWTRAK malware infection and the "software restriction (Group Policy)" message targeting security scanners.

HKLM Group Policy restriction on software: C:\Documents and Settings\All Users\Application Data\Symantec <====== ATTENTION
HKLM Group Policy restriction on software: C:\Documents and Settings\All Users\Application Data\Malwarebytes <====== ATTENTION
HKLM Group Policy restriction on software: C:\Documents and Settings\All Users\Application Data\McAfee <====== ATTENTION
HKLM Group Policy restriction on software: C:\Documents and Settings\All Users\Application Data\AVAST Software <====== ATTENTION
HKLM Group Policy restriction on software: C:\Program Files\Common Files\Symantec Shared <====== ATTENTION
HKLM Group Policy restriction on software: C:\Program Files\Symantec <====== ATTENTION
HKLM Group Policy restriction on software: C:\Program Files\AVAST Software <====== ATTENTION
HKLM Group Policy restriction on software: C:\Program Files\AVG <====== ATTENTION
HKLM Group Policy restriction on software: C:\Program Files\Malwarebytes' Anti-Malware <====== ATTENTION
HKLM Group Policy restriction on software: C:\Program Files\Ad-Aware
HKLM Group Policy restriction on software: C:\Program Files\Spybot <====== ATTENTION
HKLM Group Policy restriction on software: C:\Program Files\a-squared Anti-Malware <====== ATTENTION

Farbar Recovery Scan Tool (FRST) is an advanced specialized tool useful for removing malware when other tools fail including this software restriction issue. However, the use of FRST (and posting of it's log) is prohibited in this forum per this pinned topic.

Please follow my instructions.

After doing this, please reply back in this thread with a link to the new topic so we can close this one.

Please follow the instructions in the Malware Removal and Log Section Preparation Guide starting at Step 6.
  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running FRST which will create two logs.
When you have done that, post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs...start the new topic anyway. Explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.
