May I chime in? The Windows AIS firewall do "not" conflict with each other. They work well side by side.
I agree with craigb in that I wouldn't be a bit surprised to find IObit is causing the problem.
IObit is not to be trusted at all!
Quoth Fix It:
"Windows Firewall cannot be set as the default firewall. This problem may be occuring because of an existing Group Policy or because you are using the avast! Internet Security firewall program. If you want to use Windows Firewall, exit the troubleshooter, uninstall the other firewall program, and then run this troubleshooter again."I'm asking about avast! because the troubleshooter
specifically told me that avast! was the cause, in such a way as to suggest that this is a common problem. It specifically mentioned avast!,
and no other security program as one of two possible causes, which would mean that not only
do they, in fact, conflict, but the conflict only occurs with avast! and not security programs in general. I don't have any Group Policies, so by process of elimination, avast! is causing the problem.
In fact, I'd already mentioned this. So can we
please address the actual problem instead of quarreling about brand loyalty?
