Avast service stopped whenever browser starting

I am using the latest Free version on Windows 10. Recently I found that it is stopped regularly. I manually restart the service but then whenever I start Chrome or Firefox, the service will be stopped immediately.

I just do a repairing on Avast and restart my PC. Still the problem continues. Anything I can do to track it down ?

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

If Repair doesn’t fix the problem, try the following:
Clean Install of Avast:
