Isn’t that the whole point of a secure encrypted connection, to keep prying eyes out.

Whilst avast could probably scan the encrypted streams, but to what purpose as encryption essentially changes all signatures etc.

So there would have to be some third party intervention whereby avast redirects the outbound request to https so that the incoming https would come through some sort of proxy where it can be decrypted (similar to the way the old mail shield used to handle SSL emails). But I’m sure this isn’t as easy as this very short comment on how it might be done.
