Hello,
I installed Avast Internet Security on 2017/10/22. My home computer is a desktop, running Windows 7 Professional, permanently wired to a single VDSL modem (ZXHN H168N).
A few days after I installed Avast it happened that my office notebook failed to connect to a network share on my home desktop PC. The cause was that Avast firewall switched from Private to Public profile. The setting in Windows didn't change. I didn't touch the Avast firewall setting and I'm the only person who has access to my computer since I'm the only person in my household. I switched the firewall profile back to Private and the notebook connected all right. Since then it happened once or twice again. As a result of this experience I keep watching the Avast firewall setting, I check it more or less each time I wake up the system from hibernation or sleep and after system restart. That's how I came to the following findings.
The information on the Firewall pane in the Avast program isn't always the same. It seems surprising on a stationary, permanently connected desktop. I experienced three (3) variations:
1) Local Area Connection (Adapter) - Private Network
2) Network Connection - Private Network
3) both ad 1) and ad 2) at a time
Kind regards.
