Hello, Im opening a new topic, since noone seem to answer my last post.

I noticed that Powershell has been running in the Background. 

Here are my scans with Malwarebytes, adwarescan and FRST. (I removed the Trojan with Malwarebytes)

Is my PC safe now? Or what do I do after running FRST on my PC? Can someone please help me out?

A Remote Desktop Connection is a way to remotely access a computer's desktop. Application programs are executed on one computer (server) and displayed and operated on another computer (client). 1. A remote desktop is a separate program or function that can be found in most operating systems and gives a user access to the Desktop of a computer system enables 1. There are many use cases for remote desktop connections, such as remote maintenance, file transfer and much more .

I don't believe is available in Windows 10 Home Edition. If you do find that setting, uncheck it. That should disable Remote Desktop.

Malwarebytes Antimalware took care of the Powershell Trojan.

 

  • Download the enclosed file  Fixlist.txt
  • Save it in the same location FRST64.exe is saved.
  • Start FRST (FRST64) with Administrator privileges
  • This time around Press the Fix button and wait
  • When finished, a log file (Fixlog.txt) will pop up and saved in the same location the tool was ran from.

Download AdwCleaner and save it to your desktop.

  • Now click the Log Files tab ...
  • Double click on the latest scan log (Scan logs have a [S0*] suffix, where * is replaced by a number, the latest scan will have the largest number)

Me again, the green bar suddenly stopped moving and nothing is happening. Is the program stuck? Or do I just wait longer?

I guess, I was being impatient. The Fix was completed after a while :D.

Both files are attached below. The Fixlog is in german, although I renamed FRST.exe to FRSTEnglish.exe. Is that alright?

Hi,

powershell isnt running in the background anymore :), which weirdly used to use up 20% of my RAM. 

Is there a chance that someone might have stolen my login data on chrome? And can adding a extension cause this? I cant remember downloading something that might have downloaded a virus on my PC...

Not too savvy on Chrome, but you can restore the browser to default values.

 

  • Download the enclosed file  Fixlist.txt
  • Save it in the same location FRST64.exe is saved.
  • Start FRST (FRST64) with Administrator privileges
  • This time around Press the Fix button and wait
  • When finished, a log file (Fixlog.txt) will pop up and saved in the same location the tool was ran from.
  • You can rename FRST64.exe to its original name

Please attach this file in your next reply.

 

Please rescan with FRST and post new logs.
