Outbound connection blocked - Malvertising

[Imstaken]

I've been getting notifications from Malwarebytes saying it has blocked outbound connections to the ip address 198.134.112.243 on port 51321 for Malvertising. The file associated with it is Google Chrome (C:\Program Files (x86)\Google\Chrome\Application\chrome.exe) I looked through my report history and found that these blocked outbound connections started happening on 08/15/18. I haven't downloaded anything in the last week or so besides some games off Steam so I'm unsure how I got this problem. When I scanned my system, Malwarebytes found no threats. Any idea what is going on? Below the line is my report log.

Hello @Imstaken and

 

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

Hey Ron,

I appreciate you giving me an easy to follow guide. I've run all 3 programs and attached the 3 requested files along with a log from AdwCleaner. 

Thanks,

Looks to just be some junk added to Chrome. No obvious infection in the logs.

Please follow the advice from the following topic and let me know  if it corrects the issue.

 

Thanks

Ron
