Since installing Avast, I cannot see all the computers on our network. The troubleshooter says I need to allow my homegroup to communitcate through the non-microsoft firewall - how do I do this? thank you.
Did you install avast! Internet Security? i.e., antivirus + firewall?
You can set the network to “Home” or “Work” or “Public”. The most sharable resources are on “Home”.
