Possible Malware/Miner (FRST/Addition Attached)

Hey Guys,
Downloaded something and it locked me out of booting up, basically it would just show my command prompt and I would have to manually start explorer through the task manager. Friend of mine said he used the same download and it installed a Miner on his PC. Hoping someone could help out with this

Sorry you've been kept waiting.

Just looking over your logs now, I'll get back to you as soon as I've finished analysing them.

Please note that all instructions given are customised for this computer only, the tools used may cause damage if used on a computer with different infections.

If you think you have similar problems, please post a log in the "Infected? Virus, malware, adware, ransomware, oh my!" forum and wait for help.


Unless informed of in advance, failure to post replies within 3 days will result in this thread being closed.


Hi

I'm Gary R,

Before we start: Please be aware that removing Malware is a potentially hazardous undertaking. I will take care not to knowingly suggest courses of action that might damage your computer. However it is impossible for me to foresee all interactions that may happen between the software on your computer and those we'll use to clear you of infection, and I cannot guarantee the safety of your system. It is possible that we might encounter situations where the only recourse is to re-format and re-install your operating system, or to necessitate you taking your computer to a repair shop.

Because of this, I advise you to backup any personal files and folders before you start.

As an added safety precaution, before we start removing anything, I'd like you to make a backup of your Registry, which we can restore to if necessary.

Please click on THIS link, and follow the instructions for installing TCRB and creating a backup of your Registry.

Please observe these rules while we work:
  • Do not edit your logs in any way whatsoever.
  • Perform all actions in the order given.
  • If you don't know, stop and ask! Don't keep going on.
  • Please reply to this thread. Do not start a new topic.
  • Stick with it till you're given the all clear.
  • Remember, absence of symptoms does not mean the infection is all gone.
  • Don't attempt to install any new software (other than those I ask you to) until we've got your computer clean.
  • Don't attempt to clean your computer with any tools other than the ones I ask you to use during the cleanup process. If your defensive programmes warn you about any of those tools, be assured that they are not infected, and are safe to use.
If you can do these things, everything should go smoothly.

It may be helpful to you to print out or take a copy of any instructions given, as sometimes it is necessary to go offline and you will lose access to them.


For the duration of this "fix", I need you to remove Avast, and use Windows Defender (or whatever they're calling it these days) as your defensive program.

So please uninstall the following programs ....

Avast Premium Security
Avast SecureLine VPN

... and reboot your computer afterwards to complete the uninstall.

You can re-install Avast once we've finished, but to be honest personally I would recommend you do not.

Once that's done, I'd like you to run a new scan with FRST, and post me the new FRST.txt and Addition.txt logs.

No sign of any active malware in your logs, however it does not look as if Avast has been totally removed, and your logs do show that Avast was causing a number of code integrity problems, so we need to remove the remnants and see if that affects anything.

So ....

  • Start FRST in a similar manner to when you ran a scan earlier, but this time when it opens ....
  • Press Ctrl+y (Ctrl and y keys at the same time)
  • A blank randomly named .txt Notepad file will open.
  • Copy and paste the following into it (don't include Code: Select all) ....
Code: Select all

Avast is still being shown as enabled, so to remove these false indications please do the following ...

Removing false AV and Firewall notifications in WMI using wbemtest.exe

  • Click Start > Run then type wbemtest.exe into the Open: box, click OK
  • This will launch Windows Management Instrumentation Tester
    • Click on the Connect button.
    • In the box at the top, where it says root\default change it to say root\securitycenter then click Connect
    • Click on Enum Instances
    • In the box that opens, type antivirusproduct and click OK
    • A box will open with a list of the anti-virus programmes that WMI sees on your computer.
      • Click on the one with the CLSID .... {8EA8924E-BC81-DC44-8BB0-8BAE75D86EBF} .... to highlight it, then click Delete
      • Click Close to close the Query box.
    • Click on Enum Instances
    • In the box that opens, type firewallproduct and click OK
    • A box will open with a list of the firewall programmes that WMI sees on your computer.
      • Click on the one with the CLSID .... {B693136B-F6EE-DD1C-A0EF-229B8B0B29C4} .... to highlight it, then click Delete
      • Click Close to close the Query box.
  • Exit out of Windows Management Instrumentation Tester

Reboot your computer.

DO NOT use the WMI Tester in any way other than the one described above. If you cannot find the CLSIDS I've named for removal then just exit out of WMI Tester and let me know.

Any problems with the instructions I've given you then let me know.




Do you still need to use Task Manager to start Explorer.exe each time you boot ?

OK, looks like everything Avast has been removed then ...... don't know why the last FRST logs (Frst.txt & Addition.txt) showed remnants of Avast.

As you no longer have to manually launch Explorer.exe, it looks like your problem has been resolved ..... do you have any remaining issues that need dealing with ?

If you do, please let me know what they are.
If not, please let me know so that I can give you instructions for how to safely remove FRST, and so I can close this topic.
