Avast and Windows 10.

I’m having problems with my Windows 10 and I believe that it’s Avast. I’m having the same “Critical Error” issues as with an update from an older version of Windows to after the free upgrade (windows key won’t work, apps unavailable…). Is anyone else have these problems? My rig is brand new, and I don’t really have a lot of installed products.

  • 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…?

It would also help to get the exact error message. A screenshot may be helpful.
