Yes, i have restared laptop about 10 times end each time same. It was working only in secure mode. Now i removed avast and everything works fine.
No any message, I really don't know what happens because it was uninstalling about 1hour and i restared pc because this will never end... If you will show some logs what happening then will be fine because it looks like some kind of hang...
I removed avast using yours external tool to remove it.
No any error, webrowsers were waitnig for respond.
Ping of google.com or dns 8.8.8.8 was unrechable.
Operaitng system was unstable, everything was really slow and even firefox not started...
