Yesterday 11-19-15 I updated to the new Windows 10 version. Immediately afterwards my Internet Security program refused to start up. I cannot upgrade to the 2016 version too. so I’m stuck. What to do?

  1. Download Avast Internet Security: https://files.avast.com/iavs9x/avast_internet_security_setup.exe
  2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions…!!)
  3. Reinstall Avast with the downloaded installer from point 1.
  4. Reboot.
