Help - Powershell trojan that I don't know how to deal with


Recommended Posts

Scans aren't picking up anything but Malwarebytes gives me notifications about blocking a trojan at the location of Windows Powershell. Before i installed Malwarebytes i would see Powershell opening up in the task manager a few times a day using a lot of memory and eventually freezing my PC. I also can't delete the Powershell file because I don't have permission.

Malwarebytes Antimalware has been updated to detect those miners.


Please download 
Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

  • Right click FRST(64) and select Run as administrator.
  • Make sure that under Optional Scans, there is a checkmark on Addition.txt.
  • Press Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also produce another log (Addition.txt ). Please attach this to your reply.

Welcome smile.png
 
I'll be helping you with your computer.
 
Please read this post completely before beginning. If there's anything that you do not understand, please don't hesitate to ask before proceeding.
 
Please take note of the guidelines for this fix:

  • Please note that I am a volunteer. I do have a family, a career, and other endeavors that may prevent immediate responses that meet your schedule. Do note that the differences in time zones could present a problem as well. Your patience and understanding will be greatly appreciated.
  • First of all, the procedures we are about to perform are specific to your problem and should only be used on this specific computer.
  • Do not make any changes to your computer that include installing/uninstalling programs, deleting files, modifying the registry, nor running scanners or tools of any kind unless specifically requested by me.
  • Please read ALL instructions carefully and perform the steps fully and in the order they are written.
  • If things appear to be better, let me know. Just because the symptoms no longer exist as before, does not mean that you are clean.
  • Continue to read and follow my instructions until I tell you that your machine is clean.
  • If you have any questions at all, please do not hesitate to ask before performing the task that I ask of you, and please wait for my reply before you proceed.
  • Scanning with programs and reading the logs do take a fair amount of time. Again, your patience will be necessary. smile.png
