MWB scan on boot detected issues - need threat assessment

[pcbodger]

Hi all

Ran MWB on boot this morning and it quarantined and removed 2 issues. Defender did not detect these.

C:\\WINDOWS\\SYSTEM32\\KSUSER.DLL - Trojan.FilePatch

C:\\WINDOWS\\MICROSOFT.NET\\FRAMEWORK\\V3.0\\WINDOWS COMMUNICATION FOUNDATION\\_SERVICEMODELOPERATIONPERFCOUNTERS.REG - RiskWare.ExtensionMismatch

Full log below

The only thing out of the ordinary I did yesterday was download Teamspeak 3 (no extras) and did a scan before installing it. I have a niggling feeling it is related because KSUSER.DLL is audio related.

I am running W10 Pro 64B with Defender and MWB premium. I have them both set to scan regularly.

I am currently doing deep scans on both.

My question is - have these been sitting here passively or is there a chance they have taken some sort of action bearing in mind I have both Defender and MWB in real time mode? Could they be false positives?

Thanks

Also ran ADWCleaner and that was clear

[pcbodger]

Update: tried to run Farbar but Wndows came up with the blue threat box and said it would put my machine at risk running it. Not sure what to do  here.

Hello @pcbodger and

The program FRST is safe and used by thousands of users daily around the World. Please tell Windows Defender or other program trying to stop you from downloading it to allow it.

 

Please run the following steps and post back the logs as an attachment when ready.

STEP 01

• If you're already running Malwarebytes 3 then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• If you don't have Malwarebytes 3 installed yet please download it from here and install it.
• Once installed then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• Once the scan is completed click on the Export Summary button and save the file as a Text file to your desktop or other location you can find, and attach that log on your next reply.
• If Malwarebytes won't run then please skip to the next step and let me know on your next reply.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

• Right-click on the program and select Run as Administrator to start the tool.
• Accept the Terms of use.
• Wait until the database is updated.
• Click Scan.
• When finished, please click Clean.
• Your PC should reboot now if any items were found.
• After reboot, a log file will be opened. Copy its content into your next reply.

 

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

• Double-click to run it. When the tool opens, click Yes to disclaimer.
• Press the Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here.
• Please attach the Additions.txt log to your reply as well.

 

Thanks

Ron
