  • Which Avast…? (Free/Pro/IS/Premier)
  • Which version…?
  • OS…? (32/64 Bit…? - which SP/Build…?)
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

Hi davecullen6,
As Async wrote we would need more information to try to reproduce the issue, how avast prevents firefox to run - no process or no window ?
Can you provide us also procmon log which would capture firefox process start.

  1. Download procmon from : https://docs.microsoft.com/en-us/sysinternals/downloads/procmon
  2. Start procmon
  3. Start firefox and induce the issue
  4. Save procmon logs ( menu File → Save… → Check all events ! and Native process monitor logs PML )
  5. upload log as zip file to avast ftp

Thank you for help !
