Hello
I am here because I have encounter a bug, I believe, because from time to time, avast will block every website excepte google and youtube, and also many online program like discord, but without informing me, and for no apparent reason. I have asked around me and I am not the only one. One of my friend stoped using avast and doesn’t have this problem anymore, but I don’t really want to change my antivirus. The problem is that this bug is random, so I can’t repeat the error when I want to.
do you have avast with firewall? if so, search forum for portscan
Update to the latest version (17.4.2294): https://forum.avast.com/index.php?topic=201729.0
