SafeZone for Windows 8.1

I wonder why I cannot use my SafeZone now on my Windows Surface Pro3 (Windows 8.1). I am using Avast Internet Security 2015.

What can I do to restore SafeZone?

Repair Avast:

  1. Control Panel → Add/Remove programs → Avast
  2. Click on ‘Repair’.
  3. Follow instructions.
  4. Reboot.
