Firefox and Malwarebytes blocking

Recommended Posts

I noticed after the latest firefox update that I started getting more frequent website blocking notifications. It only seems to occur when I go to certain sites but they're the same sites that I went on before the update. I just want to double check to make sure I'm not overlooking something that needs to be fixed on my computer. I'm currently running a norton virus scan too so we'll see if that comes up with anything.

Hello @kiwiwasabi and :welcome:

Please run the following steps and post back the logs as an attachment when ready and we'll see about getting you cleaned up.


  • 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.


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

  • Right-click on the program and select RunAsAdmin.jpg 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.

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.

Hello! Sorry for the delay. I haven't gotten a chance to do step three because of my schedule but I figured I'd give you the results of step 1 and 2 thus far. Both of which seem mostly inconclusive to me. The two PUPs that were removed were just old firefox extensions I installed myself. I'm starting to wonder if it's just the newest version of malwarebytes reacting to the newest version of firefox. I'm not 100% sure.

We just wanted to make sure that there was nothing like a more serious infection on the system. It does not look like there is one. Please post the new FRST and ADDITIONS.TXT logs when you get a moment and I'll review. You may need to do a reset on Firefox. I know that every once in a while my own Firefox gets a bit wonky and I end up resetting to factory defaults and putting back a couple extensions.

Thanks again
