After disabling port scanning a couple days ago, the blocking of my NAS and some websites seems to have subsided, though I cannot say it is the right speed etc. without some more testing, which I don't have time for right now.

The 'rules' logs do show that before I turned off port scanning, the NAS was scanning and being blocked (image named withPS), and the other image is the list of the latest rules.

That said, I'm still getting multiple entries per minute numbers of entries in the 'blocked' logs, and it shows no rule, and also links to no application most of the time.  I have tried editing it to allow 'all / all' and then deleting the rule (that the system says is not a rule) but still no change.  I changed the setting 'if there is no rule, then...' to 'allow' instead of 'auto-decide' and the log still runs, but the 'no rule' entry in the rules column is blank.  But the 'show application' still goes to nothing in the app manager.

The uncertainty of what is going on and the lack of control is what is getting to me now.

I have been using Avast for about 2 years now and haven't had any issues connecting to the internet or my router until about 9 PM tonight. I'm glad I came here... "disabling port scanning" :o did the trick. Thank you!

Hi All, same symptoms as everyone else; can't connect to NAS nor even router IP. Turned off port scan, no luck. Finally did full removal of AIS and reinstall. Then turned off port scan. That seemed to work finally.

Avast needs to fix this. I've got 6 licenses and been a customer for over 3 years. Now I've got to uninstall/reinstall on 5 other computers to fix a problem Avast created? Not good.

I have struggled with this issue for a week, access to my NAS has and all internal resources have been blocked.  I replaced the router with an old 100 Meg router and everything worked, logical assumption was that it was that the original router that had a problem.  I then replaced the original router with a shiny new router, and shazam connectivity failed within a short period of time, I have pulled my hair out and tonight I came across an anomaly, I couldn't access any internal network items or any internet sites except believe it or not Facebook.  It struck me that the Avast firewall could be an issue.  Turned it off and the world came back, plus my internal network. 

The old router I tried as part of the fault elimination had an internal address range of 192.168.20.x.  If I hadn't turned the firewall off that was my next replacement item...

Thanks, but no change for me after updating. Avast Firewall still cryptically blocking the same safe sites after a couple minutes of browsing.

Yes I did. But since you asked that, I restarted the machine a second time, and the problem may have resolved. Possibly the first reboot only initiated the update, and the second reboot finished the install of the fix. Either way, the URL's in question are now browsing with dramatically less latency, and no firewall blocking so far.

Will post here again later if these results prove short-lived.

I have the same issue with Warema Webcontrol and Linn Kazoo Client.
I tried updating by clicking the update button. Yes I rebooted too but the problem is still the same. What should be the program version after updating? My version is 17.3.2291 (build 17.3.3443.0) released on 30.03.2017 12:59:59.

Reboot again.
First reboot is needed to get the update, second one to finish the installation of it.

Thanks Eddy but still the versions and the problem are the same.
