Well, it’s not usual that a on-access scanner conflit with other on-line ::slight_smile:
Maybe the exception will be Panda that does not encrypt their signature files :frowning:
I think the only advantage disabling avast will be on resources (RAM and CPU). Of course, you have a firewall and, it will be better do not browse with avast disabled… wait until the on-line scanning finishes :wink:
