Various Malware - has left Windows 10 in a state

Recommended Posts

Using Windows 10.

I've had various bits of Malware install on my machine, including Max Video Player and Wajam.

It appears I have removed most of it but it has left my PC in a state. Some Wajam files keep coming back though.

AVG won't start and I cannot reinstall or uninstall it (click on these buttons does nothing). Even clicking on the freshly downloaded install EXE file does nothing.

Windows Update no longer works (error is: 0x80070422)

Google Chrome takes minutes to load some websites now.

I use Classic Shell for my Start Menu - I can't often get to 'Programs' as it crashes Windows Explorer.

I'm thinking reinstalling Windows is the best option but I'd rather not.

That being said - going onto 'Settings' and 'Recovery' and trying to reset the PC does nothing.

Any ideas?

Hello otronics and welcome to Malwarebytes... Run the following:

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). 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.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...
 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"

  • Press Scan button to run the tool....
  • 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 make a log named (Addition.txt) Please attach that log to your reply.

Thank you,

Kevin

Hello otronics and welcome to Malwarebytes,

Your logs indicate smartservice infection, to defeat that infection you will need access to a spare PC and a USB Flashdrive 4GB or above.

First do the following on the infected PC:

Open FRST, copy/paste the following inside the text area of FRST. Once done, click on the Fix button. A file called fixlog.txt should appear on your desktop or the folder you saved FRST to. Attach it in your next reply.

Start::
CMD: bcdedit.exe /set {bootmgr} displaybootmenu yes
CMD: bcdedit.exe /set {default} recoveryenabled yes
End::

Next,

Boot up your spare PC plug in the flash drive, navigate to that drive, right click on it direct and select format. Quick option is adequate...

Next,

On that same PC downoad and save FRST to same Flash drive, make sure to get the correct version, if you are unsure d/l and save both, only the correct one will run. Do not plug Flash Drive into sick PC until booted to Recovery Environment.

Next,

Boot sick PC to Recovery Environment, if you are unsure of that action have a read at the following link, maybe bookmark for future reference...

From the Windows 10 Tutorial you should get access to the Advanced Startup Options at boot for Windows 10

  • Select Command Prompt
  • In the command window type in notepad and press Enter.
  • The notepad opens. Under File menu select Open.
  • Select "Computer" or "My PC" and find your flash drive letter and close the notepad.
  • In the command window type E:\frst64 or E:\frst depending on your version. Press Enter Note: Replace letter E with the drive letter of your flash drive.
  • The tool will start to run.
  • When the tool opens click Yes to disclaimer.
  • Press Scan button.

Hello.

Thanks for this.

When clicking 'Fix', it asks for 'fixlist.txt'.

Where can I find this file?

Best regards.

Got it - thanks.

I don't have access to a 2nd computer or flash drive for another week sadly.

Is there any other way or something else I can do in the meantime?

Unfortunately the fix I gave is the only way to defeat smartservice infection other than wipe your hard drive and reinstall windows...

I thought that might be the case.

I'll drop a message back on here a week tomorrow when I have access to another PC again.

I can't find too much on what smartservice actually does, ie/ does it mine data or something else? It would be useful to know how careful I should be online for the time being.

Thanks.

I just leave your thread open until you reply, normally I close out threads after 5 days inactivity... Regarding smartservice infection, have a read at the following link, the name is changed but infection is the same...

I had some time and nothing to lose (all data is backed up) and I have manually removed any trace of malware I can find.

The computer is running much better.

Various malware scans now show no infection but the internet is cutting out regularly still.

Latest FRST logs are attached.

Also, how do I stop the boot menu appearing when the PC starts?

I thought I sorted it but it still appears for just shy of a second when it never used to at all.

Thanks for those logs otronics,

The main part of smartservice infection seems to have been removed, there are some remnants..

continue as follows....

Select the Windows key and X key together, from the xmenu select Command Prompt (Admin)

At the prompt either type or copy/paste the following commands, select enter after each command:

bcdedit /set {bootmgr} displaybootmenu no
Exit

Next,

Turn on System Restore: https://www.thewindowsclub.com/system-restore-disabled-turn-on-system-restore-windows

Next,

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Open Malwarebytes Anti-Malware.

  • When complete click on Export Summary after deletion (bottom-left corner) and select Copy to Clipboard.
  • Wait for the prompt to restart the computer to appear, then click on Yes.

To get the log from Malwarebytes do the following:
 
  • Click on the Reports tab > from main interface.
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:

It is much better although internet is cutting out still.

However, I'm not on a known internet connection and won't be until Sunday. I'll test it then.

Start Menu > Search > For Files and Folders does nothing. Ie/ clicking 'For Files and Folders' doesn't open any window.

How do I fix that?

System file checker found no problems.

Latest FRST logs attached.

Hello otronics,

Aplogies for the late reply, am away from home and available internet access is poor... Have just checked over the FRST logs again, do not see any obvious malware or infection. However one entry in the Addition.txt log does not seem quite right...

Task: {09E93998-4A6D-427C-BB17-B922CD4B9310} - System32\Tasks\AVG\Overseer => C:\Program Files\Common Files\AVG\Overseer\overseer.exe [2018-09-17] (AVG Technologies)

I`ve only ever seen overseer.exe used by Avast, not AVG

Upload that file to VirusTotal to be checked out, even if it comes back clean can you delete that task and see if it makes any difference...

Go to http://www.virustotal.com/
 
  • Click the Choose file button
  • Navigate to the file C:\Program Files\Common Files\AVG\Overseer\overseer.exe
  • Click the Scan it tab
  • If you get a message saying File has already been analyzed: click Reanalyze file now
  • Copy and paste the URL address back here please.
  • Repeat the above steps for the following files

Next,

Can you also zip up and attach the following folder:

C:\WINDOWS\Minidump
 
It will probably have to be copied to your Desktop first...
 
Thank you,
 
Kevin

C:\WINDOWS\Minidump is an empty folder.

There are various issues with the laptop that I have discovered:

* Windows search not working.

* I cannot change the default media player from VLC to Winamp no matter what I do.

* Adjusting screen brightness after the laptop wakes from sleep takes ages to respond.

I might just have to wait until the next Windows build is released to see if that fixes these issues.

System refresh is an option to try, all of your personal stuff is saved. Windows is reinstalled along with software that came with your system or was downloaded from the app store. Any other software you downloaded frrom 3rd party sites would have to be reinstalled after refresh is completed...
