Avast Premier 2015 - Blocks all web access after ~10 Minutes

Greetings,
Patched my Avast Premier this morning on my Windows 7 x64 Machine and after 10 minutes all websites are blocked. I’ve disabled the browser plugin and it’s still blocked. On reboot I get another 10 minutes of use. It does not however block other network traffic. I can still listen to spotify, use RaidCall & Teamspeak, and talk to my VPN. I disable avast for 10 minutes and web comes back.

I have 5 other machines running Avast Free that also updated and none of them have any problems. I have run MalwareBytes, CCleaner, and Avast boot time scan with no problems detected. Just happened today after patch.

Has the fan club gotten any updates as to a possible fix? I just don’t get why the Paid version gets all the major issues that prevent me from doing my job when the free version just works.

Try a repair…Control Panel>Uninstall a Program>double click “avast”>click “repair”>reboot.

Was this a “clean” update or over the top?

I had same problem on my second laptop running Avast IS 2014/2015. I did not know how to bypass that problem with version 2014, but after installation of 2015 Avast reported information that Secure DNS cannot work on this network.

After removing Avast 2015 and installing back without Secure DNS option during custom installation net started to work again. Sometimes during start-up avast block a net for few minutes but afterwards net will start again.

In addition I did not installed Grime Fighter and Secure VPN.

Hope this fix will sorted out your problem.
