dllhost.exe COM surrogate leaching my computer


Recommended Posts

Malwarebytes stopped several outgoing access attempts during web browsing last evening.  Followed Malwarebytes popup suggestion and added to Excluded List.  However, my computer is really dragging and running slowly.  Looked in Task Manager and there area about 20 instances of dllhost.exe running at the same time.  I scanned the computer again with Malwarebytes and Avira anti-virus, but nothing is showing up.  Cannot figure what's up with the numerous dllhost.exe processes eating up memory.  Is this a malware or Trojan that is not being picked up by Malwarebytes and Avira (yes - both are up to date)?

Followed Malwarebytes popup suggestion and added to Excluded List.

This wasn't a suggestion. By excluding the site, you're telling MBAM to allow your computer to connect to these malicious sites. I suggest you reverse the exclusions. Open MBAM -> Settings -> Web Exclusions -> Remove
 

Is this a malware or Trojan that is not being picked up by Malwarebytes and Avira (yes - both are up to date)?

This malware is called Poweliks, and resides entirely within the registry. Please run the following programme below to confirm this is the infection present. 
 
STEP 1
xlK5Hdb.png Farbar Recovery Scan Tool (FRST) Scan

  • Please download Farbar Recovery Scan Tool (x32) or Farbar Recovery Scan Tool (x64) and save the file to your Desktop.
  • Note: Download and run the version compatible with your system (32 or 64-bit). Download both if you're unsure; only one will run.
  • Right-Click FRST.exe / FRST64.exe and select AVOiBNU.jpg Run as administrator to run the programme.
  • Click Yes to the disclaimer.
  • Ensure the Addition.txt box is checked.
  • Click the Scan button and let the programme run.
  • Upon completion, click OK, then OK on the Addition.txt pop up screen.
