Avast suite conflict with windows 7

I install AVAST free ok on my system. I have purchased AVAST suite and it all loads ok, when I restart though the computer simply comes up with a green screen with black vertical lines! I then need to reboot, start in safe mode and go to restore point before download. Does anyone know if there is a setting or problem in windows 7 that conflicts with full internet security packs and if there is a solution

I’m with Windows 7 and AIS… no problems.
Any other security program in your computer? Firewall?
And in the past?

I suggest an installation from scratch:

  1. Download the latest version of avast! Uninstall Utility and save it.
  2. Download the latest avast! version and save it.
  3. Uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
  4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after you’ve run it.
  5. Install avast! using the setup saved on 2. Boot.
  6. Register your free copy or add the license key for Pro.
  7. Check and post the results.

I suggest you check your graphics card ;D ;D ;D ;D ;D ;D ;D
