This morning I upgraded to the latest Windows 10 build 10130 and had NO INTERNET.
My computer has two internet adapters
One Intel
and
One Realtek
Neither one would work
I tried disabling Avast but it was no help until I completely removed Avast Premier.
I'm running Avast Internet Security on Windows 10 Build 10130
It appears that the Avast Firewall Module is not compatible. It is disabled after the update to 10130 and can't be started.
I tried a repair of Avast without success. The only thing that worked, Was to change Avast and uninstall the Firewall module.
Once that was done, AIS works without any further problems and the Windows Firewall is now working in place of the Avast Firewall module.
This certainly needs to be addressed but for now it's a workaround that I can live with.
