Malwarebytes detects that my prefs.js is a virus. How is this possible? Should I be concerned? What do i do about this?

Pref.js is a text file that only contains configuration data and Firefox settings. Does Malwarebytes give any detail about what is wrong? You should contact Malwarebytes about this.

Did you recently started using Malwarebytes or are you using it for a long time (i.e. did this data recently get added or could this be a leftover entry, possibly from a Legacy extension, in prefs.js that is no longer used)?

I've used malwarebytes for many years. But I recently clean installed my PC with win 10. I copied my ff profile in it after it was clean installed. I do remember that before I saved my profile that I was having an issue with ff where in the top of ff Options it kept saying, "Your organization has made changes to your software...." something along those lines.
