Website Blocked due to PUP at Firefox start


Recommended Posts

13 minutes ago, SteelSlicer said:

I get the same message every time I start Firefox, for about 5 days now. Window 10 Pro, Malwarebytes Premium 4.5.14 and Firefox 102, all up to date. No new addons in months. I installed a video editor last week, DaVinci Resolve, pretty sure there were no pups attached.

Please do the following so that we may take a closer look at your installation for troubleshooting:

NOTE: The tools and the information obtained is safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

 

  • Download the Malwarebytes Support Tool
  • In your Downloads folder, open the mb-support-x.x.x.xxx.exe file
  • In the User Account Control pop-up window, click Yes to continue the installation
  • Run the MBST Support Tool
  • In the left navigation pane of the Malwarebytes Support Tool, click Advanced
  • In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine
  • A zip file named mbst-grab-results.zip will be saved to your desktop, please upload that file on your next reply

Thanks

Hello  and  :welcome:      @SteelSlicer

 

My screen name is AdvancedSetup and I will assist you with your system issues.
 

Let's keep these principles as we proceed. Make sure to read the entire post below first.

  • Please follow all steps in the provided order and post back all requested logs
  • Please attach all log files to your post, unless otherwise requested
  • Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans have been completed.
  • Temporarily disable Microsoft SmartScreen to download the software below if needed. Make sure to turn it back on once the scans are completed.
  • Searching, detecting, and removing malware isn't instantaneous and there is no guarantee to repair every system.
  • Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
  • Do not run online games while the case is ongoing. Do not do any free-wheeling or risky web-surfing.
  • Only run the tools I guide you to use. Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • Cracked, Hacked, or Pirated programs are not only illegal but also can make a computer a malware victim. Having such programs installed is the easiest way to get infected. It is the leading cause of ransomware encryption. It is at times also a big source of current Trojan infections. If there are any on the system you should uninstall them before we proceed.
  • Please be patient and stick with me until I give you the "all clear". We don't want to waste your time, please don't waste ours.
  • If your system is running Discord, please be sure to Exit it while this case is ongoing.

 

 

Please go to Control Panel, Programs, Programs and Features and uninstall the following

Are you still using BackBlaze for backup?

HKU\S-1-5-18\...\Run: [Backblaze] => "C:\Program Files (x86)\Backblaze\bzbui.exe" -quiet (No File)

 

 

Check your USER.JS file for Firefox and make sure that website is not listed.
