Please help us to find root cause of this problem

Run command prompt (Start → type “cmd”) and navigate to this folder:

c:\ProgramData\AVAST Software\SZBrowser\profile\YOURUSERNAME\Extensions\

Then run this command:
dir /S > c:\test.txt

Please attach the test.txt file here.

Also:

  • are you user with admin rights?
  • What OS do you use? (cmd → winver) mention the version of OS build
  • does it work properly when you launch the browser as administrator? (rightclick on the icon, run as administrator)

Thank you very much
