Just to let you guys know first Comodo don’t recognize Avast 7… Second of all PC is very slow… Third I have a problem shutting down my PC… Black screen for few sec… WIN7 64 bit… Never had an issue with Avast 6 and Comodo…
It isn’t unusual when you update a program that files change and firewall can block the changed files.
Ensure that any entries relating to avast in comodo firewall for avastSvc.exe, avastUI.exe and avast.setup. That should force comodo firewall t ask permission again.
try adding all of avast’s file to comodo’s trusted program list… im using comodo firewall d+ with avast here and no prob… except that on the program update it gave me an alert that avast service trying to do something but probably comodo wasnt updated with avast 7 yet so yeah give it some time
