Hello. I have three PCs on my home network, all running Avast Internet Security. After the Avast update today, the computers started having problems seeing each other.
When I disable the Avast Firewall portion of Avast on all three, then everything is great. Each PC can see the other two PCs.
What setting do I need to change in Avast Firewall to ensure all of my PCs resume seeing each other?
Thanks
Mark

Network profile to private

Thanks. The PC that first had the problem is acting weird. That setting had indeed gotten changed to PUBLIC. But now when I try to change it to PRIVATE, the setting literally changes back to PUBLIC all by itself after about 1 second.
Any ideas why this might be happening?

Tried change and reboot?

I uninstalled Avast and re-installed. The same problem is happening.
As soon as I set it to PRIVATE, it rolls back to PUBLIC.
This is not happening on my other two computers.
I am running Windows 7 on all three.

Time to try bob3160's clean install procedure:
https://forum.avast.com/index.php?topic=224161.msg1488303#msg1488303 (https://forum.avast.com/index.php?topic=224161.msg1488303#msg1488303)
Tho the topic is different, the procedure is the same and the reason is the same, to fix program glitches.
Bob has also provided a link for using avastclear.exe: https://youtu.be/p-h3myRD51A (https://youtu.be/p-h3myRD51A)

Thanks. I did use Revo uninstaller for just that reason but will try these options also.

No, this is not fixed & would hope that Avast do something useful about this, ie:
Clean Install, latest version of Avast Premier. LAN set to Private Network.
Other Network PCs cannot be seen, files & dirs not shared etc.
Turn off Avast firewall and they can. This is consistent.
The one preference that allows (some) access is to turn ON Firewall /Internet Connection Sharing Mode. However, of course this seems to be a kludge & is not what that preference is intended for, ie: I do not want or need to share Internet connection, rather, simply share files on a Home Private LAN.
Further, if AVAST is bypassed completely, I can also see a share MacOS computers on the same network; also see and access other peripherals such as LAN router, NAS, Apple TimeCapsule etc.
Finally, while we're at it: is impossible to access TV Chromecast without turning off AVAST Firewall. In all cases as per above, the built-in Windows Security & Firewall functions perfectly.
