CHA05,
You will find the Avast team is very open to feedback here.
Regarding the issue, this is going to be something that is a challenge for all security software. How do you inspect the traffic if its encrypted? Currently doing a HTTPS man in the middle style scanner does have drawbacks, but is best solution currently available. Otherwise, it would bee too easy for a malware author to just hide the traffic in an HTTPS tunnel to avoid detection!
Cheers,
Mac
