After recently updating both Mozilla and Avast Pro Antivirus I can no longer log onto internet (Shaw) with either Mozilla or Internet Explorer, but can with Avast Safe Zone. Attempts to log on with Mozilla or Internet Explorer I get: Error code: MOZILLA_PKIX_ERROR_INVALID_INTEGER_ENCODING

How do I fix this?

With Shaw cable internet there is no account login per say.

It is possible the Avast could be blocking applications such as Firefox and IE to internet with its firewall application rules.
