RTP detections followed by weird network state

Hello! Following this thread in another section, I was advised to run FRST and post the log here just in case.

The short version of the story is that Malwarebytes reported blocking a bunch of outgoing connection attempts to 104.194.10.57, every 30 seconds, for about 15 minutes, after I visited a web page. (As of the time of writing, this is not reproducible anymore; I'm probably getting served different ads.) So this was most likely a blacklisted ad provider's address. The actual WEIRD part of that story is that something along the way made my internet connectivity go into a weird half-working state: DNS stopped working, LAN http connectivity (router interface page @ 192.168.1.254) stopped working, but... a multiplayer game's ongoing connection did not go down, and kept working?! Windows displayed the connection as "No Internet", too. Rebooting made all of that go away. No problem now.

This is why I initially posted a thread to the program tech support section, as I was suspecting a bug in Malwarebytes more than an actual infection. (It wouldn't be my first time encountering a strange bug caused by MB!)

However, better safe than sorry, so I've attached MSERT and FRST logs to this thread. I'll note that I was unable to run the standalone version of FRST—it seemingly freezes after reaching "Memory info" in the scan progress. (The process is still reported as running, but the interface completely freezes.) It did leave logs behind, and they looked identical to the FRST scan included with the "Malwarebytes Support Tool", which itself ran fine. So I'm attaching the logs from that one instead.

Hello @MaxLebled

 

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

Please make sure you disable any real-time antivirus or security software before running this script. Once completed, make sure you re-enable it.

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 that cannot be undone.

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) or wherever you ran FRST from. Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1:  This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. It will also run a disk check on the restart to ensure disk integrity. Depending on the speed of your computer this fix may take 30 minutes or more.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed. The use of an external password manager is highly recommended instead of using your browser to store passwords.

NOTE-3: As part of this fix it will also reset the network to default settings including the firewall. If you have custom firewall rules you need to save please export or save them first before running this fix.

The following directories are emptied:

  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome, and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Flash Player cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

fixlist.txt

Thanks

How long should I expect the fix step to take? It doesn't seem to be working. FRST is displaying a moving progress bar, but fixlog.txt pretty much just contains fixlist.txt. As I type, fixlog.txt hasn't been written to since I started the process 15 minutes ago. Cookies weren't cleared from my browsers either.

I have been running the tool as instructed, and with all background programs (MB included) closed.

Great, that looks better. The SFC scan also found and corrected issues, which is good.

Windows Resource Protection found corrupt files and successfully repaired them.

 

Please run the following

 

Microsoft Safety Scanner

Please make sure you Exit out of any other program you might have open so that the sole task is to run the following scan.   
That goes especially for web browsers, make sure all are fully exited out of and messenger programs are exited and closed as well
 

STEP 1

Please set File Explorer to SHOW ALL folders, all files, including hidden ones.  Use OPTION ONE or TWO of this article

https://www.tenforums.com/tutorials/7078-turn-off-show-all-folders-windows-10-navigation-pane.html

STEP 2

I suggest a new scan for viruses & other malware. This may take several hours, depending on the number of files on the system and the speed of the computer.

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted software from a system. 

The download links & the how-to-run-the tool are at this link at Microsoft 

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

 

Look on the Scan Options & select the FULL scan.

Then start the scan. Have lots of patience. It may take several hours.

  • Once you see it has started, take a long long break;  walk away.  Do not pay credence if you see some intermediate early flash messages on the screen display.  The only things that count are the End result at the end of the run.
  • The scan will take several hours.  Leave it alone. It will remove any other remaining threats as it goes along.  Take a very long break, do your normal personal errands .....just do not use the computer during this scan.

This is likely to run for many hours as previously mentioned  ( depending on the number of files on your machine & the speed of the hardware.)

The log is named MSERT.log  and the log will be at C:\Windows\debug\msert.log

Please attach that log with your next reply.

Thank you

Here's the MSERT log... there are a couple of embarrassing detections in there, of very old pirated software, that is lying around in backups of backups of backups (...) of backups. But rest assured I've never gone anywhere near these for nearly a decade—for at least 3 (!) computers ago. I nuked 'em out of my backups drive.

Everything's been good, it was just that strange instance of my network going down in the previously-mentioned way after those IP blocks. Figured it might be a MB bug (not the first one I'd have encountered) so I might as well post in case there was a bug to be found & solved
