Firewall Blocking Everything

i have the same problem and doing same thing.  Was waiting on response.  If I find out anything will pass along

HI
After a recent windows 10 update (shutting down and restarting) my laptop is blocked from using the internet.  I can see that a useable connection through wi-fi or tethering exists but I cannot access anything on the net, either by searching ot the automatic update functions either.

I can gain complete access by switching off the AVG firewall.  Onviously this is not a good situation.  Can somebody please help.

Neill, I disabled my firewall and then went back in and enabled firewall.  This prompts a restart, after restarting I now have access to internet. Not sure what I did, but it seems to have solved issue for now
