RejZor, I change this keys every time I uninstall/install avast! again. Because of them - and kubecj + vlk help - I’m here ;D

If you use RegistrarLite (Registry Editor), you can change the order of the drivers there. Put avast! in the first place and Symantec in the second.

This is a bug of Symantec! NAV puts two groups of zeros in the middle of the key, avoiding any other product to use that key correctly.

If you do not correct them, you won’t be able to execute .exe files in a cmd window (DOS under XP) and you won’t have a lot of files scanned (.exe, .com…): eicar test will fail >:(

Ask me whatever you want about this subject!
