Hello everyone!
I'm facing quite a doozy here. A user is receiving an error message "powershell has stopped working, a problem caused the program to stop working correctly." every couple minutes or so. Thinking this was Poweliks, I downloaded and ran the ESET tool, but it reported that it could not find the virus.
 
Whenever the "powershell has stopped working..." error message pops up, in task manger, I see the following entry:

I've tried scanning with malwarebytes, adwcleaner, jrt, tdsskiller, and combofix but none of these found the root cause. Any help/advice would be much appreciated!

You may be infected with Poweliks or Xswkit (aka Gootkit, a Poweliks clone) which typically affects the ability to browse or download files using Internet Explorer and causes PowerShell error alerts. Task Manager typically shows numerous occurrences of (COM Surrogate) dllhost.exe or dllhst3g.exe. If using a 64-bit version of Windows, then these entries will be listed as dllhost.exe *32 or dllhst3g.exe *32. These processes are known to spawn and consume a large amount of system resources. When attempting to download files in Internet Explorer you may receive the message "Your current security settings do not allow this file to be downloaded." or you may see a pop-up alert advising that "powershell (powershell.exe) has stopped working".

If you are having trouble downloading files with Internet Explorer, follow these instructions to re-enable downloads/reset all Security zones to default.

Please download ESETPoweliksCleaner and save it to your Desktop logo.png
  • Double-click on ESETPoweliksCleaner.exe to start the tool.
  • Read the terms of the End-user license agreement and click Agree if you agree to them.
  • The tool will run automatically. If the cleaner finds a Poweliks infection, press the Y key on your keyboard to remove it.

    .
  • If Poweliks was detected "Win32/Poweliks was successfully removed from your system" will be displayed.
  • If Poweliks was not detected "Win32/Poweliks not found" will be displayed.
  • Press any key to exit the tool and reboot your computer.

    .
  • The tool will produce a log in the same directory the tool was run from.
  • Copy and paste the contents of that log in your next reply.
Note: If the log is too long...you may need to split it and use multiple replies in order to post all the information.
