hi, i am experiencing the EXACT same problem as the thread poster....Avast VPN slider button moving to "turning off" when i am done visiting certain sites but the switch on the screen then just spinning and not turning off, hanging like that and then no internet access. Just cant get out of it until i reboot. Sometimes it takes down my whole Win10 and i get blue screen "YOUR PC HAS CRASHED

" after 5 or 10 minutes if i continue to struggle on with the PC.
this started happening about 3 or 4 days ago. Its frustrating as hell.
I have re-installed Avast VPN. No diff.
i am also running Avast Premium Security. I wonder if the two have a clash problem. The firewall in the APS is quite screwy, sometimes i need to toggle the firewall switch to get internet access when i start the PC for some reason. It seems to fight with the Windows Firewall and needs a toggle to get the two accepting who is in charge or something. Any rate this is probably an unrelated problem and has been going on for some weeks now.
This problem with VPN has been only the last 3 or 4 days.
Please help its driving me bonkers my whole system has ground to a halt
