Avast Firewall is automatically IP blocking a trusted website

[REDACTED]

I have the same Issue on my own Website mallorca-forum.com and there is no knowing Problem with a Port Scan Attack against Visitors. Just at Sunday i have that Problem like other Users, so i think there is a Avast Program Bug or something.

so I think there is a Avast Program Bug or something.

I agree.

Judging from other bug reports in the forum, it looks like Avast Firewall isn't tracking outgoing requests to see if incoming packets are in reply. I thought "port scanning" blocking was suppose to be in response to unsolicited packets arriving at various ports.

Asyn, thanks for the link to the other thread. However even though this is a "known issue", there seems to be no permanent fix on offer in any of the threads, including that one. Avast Firewall still blocking specific harmless websites after a couple minutes of browsing, in a cryptic manner without providing any pop-up notifications.
