Powershell Trojan Removal

Recommended Posts

Hello,

My in-laws have MalwareBytes Premuim, and have an infection from a Powershell Trojan virus.  Maywarebytes seems to be blocking the outbound communications, but I'm having a hard time removing it.

So far I've run RKILL, a full MWB scan (with root kit detection), I've run adwcleaner, FARBAR recovery scan, and Sophos scan ... but the infection is still active. 

Here is the log from the MWB block notifcation, and I've also attached log files from the other scans.

Any help would be greatly appreciated!

Hello, Welcome to Malwarebytes.
I'm nasdaq and will be helping you.

If you can please print this topic it will make it easier for you to follow the instructions and complete all of the necessary steps in the order listed.

Please download the attached Fixlist.txt file to  the same folder where the Farbar tool is running from.
The location is listed in the 3rd line of the FRST.txt log you have submitted.

Run FRST and click Fix only once and wait.

The Computer will restart when the fix is completed.

It will create a log (Fixlog.txt) please post it to your reply.

Please post the Fixlog.txt and let me know what problem persists.

Thanks for the quick reply.  Here is the log result.  I won't know if the issue is still present for a while though, as it seems to phone home at random intervals.

Will do.  I've since driven home, but will check in with them to see if the infection is gone.  If not, I'll be back around Christmas to finish it up.

Thanks again for your help, it is greatly appreciated!

@nasdaq I just contacted them to check the history, and there hasn't been another log entry of powershell.exe trying to send outbound comms in over 24 hours.  So I believe the issue has been resolved.
