My ESET scan recently informed me that I have an infiltration on my powershell.exe(3436) a variant of the Kovter.C Trojan. I have run Eset Scans again, however it always refinds this at the start of the initial scan. What all can I do to remove it please?

Hello TXRednexican and welcome to BleepingComputer!    :)

 

My name is Sirawit and I'm here to help you.

 

If I don't reply after 3 days, feel free to PM me.   :)

==========================================================================

Some points for you to keep in mind:

  • Backup any files that cannot be replaced. Removing malware can be unpredictable and this step can save a lot of heartaches if things don't go as planned. You can put them on a CD/DVD, external drive or a pen drive, anywhere except on the computer.
  • We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability.
  • Please do not run any tools or take any steps other than those I will provide for you while we work on your computer together. I need to be certain about the state of your computer in order to provide appropriate and effective steps for you to take. Most often "well intentioned" (and usually panic driven!) independent efforts can make things much worse for both of us. If at any point you would prefer to take your own steps please let me know, I will not be offended. I would be happy to focus on the many others who are waiting in line for assistance.
  • Do not attach logs or use code boxes, just copy and paste the text.
  • Periodically update me on the condition of your computer, and provide detail in every post.
  • In the upper right-hand corner of the topic, you will see the Followtopic.jpg button. Click on this then choose Immediate E-Mail notification and then Proceed and you will be sent an email once I have posted a response.
  • If you do not reply to your topic after 3 days I will bump the topic, if you didn't reply in next 3 days we assume it has been abandoned and I will close it.
  • Once things seem to be working again, please do not abandon the thread. I will give an "all-clean" message at the very end with some additional information on how to stay malware-free.
  • Lastly, I would like to remind you that most members here are volunteers, and sometimes "real life" can get in the way of our malware hunt. I will notify you if I know I will need to be away for longer than 48 hours.

==========================================================================

 

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 then click "Run as administrator" (XP users: click run after receipt of Windows Security Warning - Open File).
  • When the tool opens, click Yes to a disclaimer.
  • Press the Scan button.
  • When finished, it will produce a log called FRST.txt in the same directory the tool was run from.
  • Please copy and paste the log in your next reply.

Note 2: The first time the tool is run it generates another log (Addition.txt - also located in the same directory the tool was run from). Please also paste that, along with the FRST.txt into your next reply.

 

Thank you.


If I don't reply back to you in 2 days, feel free to send me a PM.
