I am running latest version of Comodo ver. 5 with Defense+ set to Proactive. I also am running MBAM Pro.

I have absolutely no exceptions in Comodo for Avast 6 or MBAM Pro. Everything runs fine. You do need exceptions in MBAM Pro for Avast 6 and in Avast 6 for MBAM Pro.

Note: I use only Comodo’s sandboxing and have Avast’s sandboxing turned off.

I think a lot of the Comodo and Avast 6 conflicts arise over which was installed first. I installed Avast 6 prior to installing Comodo 5.
