all sites. only works on firefox, chrome's version 78.0.3904.70, anti virus is symantec.
i'm also facing the problem that chrome is down with this anti virus, but solved with other ways
but now adguard is not working
Works fine here. @s0ckd3 are you using antivirus/antimalware software too? If so, what?
This *could* be an antivirus incompatibility. You could try going to Advanced Settings (AG's Settings > General Settings and scroll down to the bottom > Advanced Settings...) and unchecking/checking certain options. First, try unchecking Intercept TCP connection requests and see if it works then after pressing the green Save button. If that doesn't work, go back to Advanced Settings and check Use redirect driver mode and then press Save again and try that. If that doesn't work, try checking Filter localhost and see if that works. After trying each option (and if it doesn't work) you should revert the previous option you tried when trying a new one.
If that doesn't work, hopefully @Chinaski has some better ideas.
