After installing Malwarebytes Chrome and Firefox no longer start


Recommended Posts

Hi,

Just installed MalwareBytes 4.0.4.49 on my Windows 10 Pro PC (1903); I7 8700K with 16gigs RAM should it matter.  Running Kaspersky Total Security 20.0.14.1085(g) for firewall and antivirus.

Prior to installing MalwareBytes, both Firefox and Chome would start as soon as clicked.  After installing MalwareBytes, neither browser would start.  Firefox would appear as a Background Process in Task Manager with very low RAM usage.  Chrome would have a few crash reports appearing in Background Processes - neither would actually quit if I chose End Task.

Uninstalling MalwareBytes allows both browsers to start as expected.  Whether the issue is with MalwareBytes itself, or a compatibility issue with KTS is unclear.  Curiously, I have this version of MalwareBytes installed on my laptop which is running Win 10 Home and KTS without issue.  Any thoughts on where to begin?

Greetings,

There is currently a known compatibility issue with the latest versions of Kaspersky products.  The problem is being investigated and Malwarebytes has reached out to Kaspersky Labs to attempt to get the situation resolved.  In the meantime, details about the issue as well as the currently known workarounds are documented in this topic.

I hope this helps and if there is anything else we might assist you with please let us know.

Thanks

If you are using Kaspersky then that would be the reason for the issues as Kaspersky's latest versions conflict with the Ransomware Protection component in Malwarebytes.  If you do not have any Kaspersky products installed then it is not the same issue (though the symptoms may be similar), in which case I would recommend starting a new thread and posting the logs from the Malwarebytes Support Tool to seek assistance:

  1. Download and run the Malwarebytes Support Tool
  2. Accept the EULA and click Advanced tab on the left (not Start Repair)
  3. Click the Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

Same here!
After premium activision i cant use firefox.

Please follow the instructions above.  If you have any Kaspersky products installed then please refer to the workarounds and information in this topic, but if you don't have any Kaspersky products installed then please create a new topic and post the requested logs so that someone may assist you further in diagnosing the issue.

I have premium and Chrome, Firefox and Thunderbird all work fine for me, so this issue is not universal to all systems.  Please follow the above instructions to seek assistance in getting the issue corrected.

Thanks

Please create a new topic so that you have your own thread to work in and run the Malwarebytes Support Tool and have it create the logs as detailed in this post and then attach the resulting ZIP file in your new topic so that someone can take a look and investigate what is going on with your system and installation.  This thread had to do with Kaspersky and has been addressed so please just create your own thread and post the requested logs there and someone will help you.

Thanks
