Outlook Add-on keeps disappearing

I’m asking for my boss, but did anyone ever solve the issue where the Avast add-on will disappear and need to be re-enabled each time you close the program? I’ve seen in the forum that other people have had this same issue, but no one has posted a solution that I could find.

  • 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…?
