After updating to 2016.11.1.2253 (Win7 64Bit with Avast Internet Security 2015) there is no longer a Network Connection available.
The computer could not get an IP-adress via dhcp.
Using an manual IP did also not work.
netsh int ip reset and netsh winsock reset did not work.
Only with a systemrecovery to the time of the avast update "“Devicedriver-Paketinstallation” it is possible to get the System working.
The next test:
Avast Update - an the same Problem.
What can I do??
Thanx!
