Windows Powershell, I believe.

[Vynlendus]

I believe that something is using Windows Powershell to infect my computer. I've tried running scans from MalwareBytes, and many other anti-rootkit providers but I can't seem to get rid of the malware. I believe the malware is using my computer on a botnet, based on this:

It seems my MalwareBytes3 didn't pick up on anything, as the last time I noticed an issue I did a scan and restarted my computer (after a few hours of my computer being on, it seems the malware returns). Though, last time I did attempt to look up the detected file, and here was the name (if it's any help). "HKU\S-1-5-31-2717128537-3816681412-2988564888-1001\CONSOLE\TASKENG.EXE|WINDOWPOSITION"

Here is the export of my AdwCleaner:

Please download the attached fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST or FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.

Thanks

I've uninstalled any versions of Java that I had, along with running the registry file you've sent. I attached the fixlog from FRST64, but I cannot seem to find C:\PROGRA~3\20707362\4f95a8ba.dll anywhere. I searched all of my C drive, and I came up with no results, so I tried searching all of my hard drives and I still came up blank

Fixlog.txt

[AdvancedSetup]

That's fine. The file may have already been removed. I removed the task schedule for it as well in the fix.

However, I also told the script to run a full disk check on reboot. You've replied much faster than you should have if the disk check ran. I'm assuming you either did not reboot or the disk check did not run for some reason.

Did the full disk check run?

 

 

[Vynlendus]

I did reboot the computer, and there was around 3-5 minutes of it scanning saying "Scanning and repairing C:" followed by the progress. My operating system is on an SSD, so that may be why.

 

The time frame could be incredibly wrong, but I feel it was no more than 20 minutes.

Edited July 30, 2017 by Vynlendus

[AdvancedSetup]

Yes, okay, if on a small SSD it will run pretty quick.

So everything okay now?

Any other signs of an infection or issue?

 

[Vynlendus]

I'm not quite sure yet. Usually after I would run any type of scan and restart my computer it would stop for a few hours, up to 2 days, and then it would randomly start up again. Though, I do believe this is by far the most intrusive scan/removal attempt, so I have high hopes for it being resolved. Would it be alright to keep the thread open for 48 hours, and if anything starts back up for me to just throw in a reply, or would you prefer if we just close the thread and if the problem persists I can PM you.

[AdvancedSetup]

No problem. The system should be clean now, but we'll go ahead and leave it open for now.

Let me know

Cheers

Ron

Hi @Vynlendus

 

How are things going? System still working good?

Please post a status update when you get a moment.

Just ran a scan, and everything is still looking great! Thank you so much for your help, Ron.

You're quite welcome. I'll go ahead then and close your topic now @Vynlendus

Take care

• Please attach the Additions.txt log to your reply as well.

 

Thanks

[Vynlendus]

I've left out the FRST logs, as I linked them previously. If you need me to re-run the scan, I'll surely do so.

Let me know if the issue appears to be fixed now or not after the reboot.

Thanks

 

[Vynlendus]

The problem is very similar to last time, where my connection is fine for 24-48 hours after restarting my PC, but then my connection will crash, and come back with 3-4Mbps, where I usually get 230-240Mbps, so I won't be able to tell if the problem has been resolved immediately. Though, here are the new files from FRST.

Let's try resetting all your browsers.

 

 

Please visit each of the following sites and let's reset all of your browsers back to defaults to prevent unexpected issues.
If you are not using one of the browsers but it is installed then you may want to consider uninstalling it as older versions of some software can pose an increase in the potential for an infection to get in.

Internet Explorer
How to reset Internet Explorer settings

Microsoft Edge
How to Reset Microsoft Edge in Windows 10

Firefox
Click on Help / Troubleshooting Information then click on the Refresh Firefox button.

Chrome
Reset Chrome back to defaults to completely clear out issues with Chrome.

• First, go to >> Google Sync << and sign into your account. Make sure you know your password as this will clear it from the browser.
• Scroll down until you see the   "reset sync" button to clear your data from the server and remove your passphrase.
• Now, close all Chrome windows. Chrome cannot be running for the next step. If needed, print this information or use another browser to read the information.
• Press the Windows key + R at the same time, to bring up the run dialog box.
  • 
• Type in (or copy/paste) the following and press Enter:     %localappdata%\Google\Chrome\User Data\Default\

1. Press Ctrl + A to select all the files and folders.
2. Hold down Ctrl + A and click once on the files "Bookmarks" and "Bookmarks.bak". This will unselect them.
3. With all the files selected (except for your Bookmarks), press the Delete key and click Yes to delete the files and folders.
4. Example of all files and folders selected, except Bookmarks

 

Restart your computer now and make sure there are no longer any redirects or other browser issues. 

 

[Vynlendus]

I've reset all of the browsers, though I'm not sure what I should be looking for to make sure it's resolved any issues.

I did notice that Chrome still had all of my "Most Visited" tabs, and I did find that a bit weird. It also has all of the suggested searches from when I would search something directly from the address bar.

Edited August 24, 2017 by Vynlendus

[AdvancedSetup]

If Chrome sync was disabled, and all those files and folders were deleted and the computer rebooted it removes all local data. But, Chrome still has a few other "history, etc" items that I think you have to go into your regular Google account and removed. I think that data is treated a bit different than Sync data.

Keep an eye on the computer and let me know if it exhibits any malware related symptoms again. Hopefully should be good at the moment now.

Ron

 

[Vynlendus]

Seems to be working perfectly now, thanks again Ron!
