Avast Internet protection blocks my internet COMPLETLY

system · 2017-04-15T16:50:48.000Z

Avast used to block my internet connection every time I started my computer but a repair(and a restart when it asked for it) fixed it until the next time I turned my computer off. It was like this for a couple of months but I decided not to to anything about it, I just sent my computer to sleep instead of turning it off…

Four days ago however I had to turn it off and now Avast is blocking all internet access to my computer. It doesn’t even show me that I have the option to connect to the internet and I use an Ethernet cable. Repair doesn’t work anymore and I had to uninstall Avast in order to get internet connection back.

Avast Internet Protection
Idk, the moment I install it it blocks the internet connection
Windows 7 Ultimate 64 bit version 6.1 build 7601
No other security software
I used Avast free, it was fine but when I upgraded it started causing problems (the internet was blocked until I repaired and now blocked completely)

Already performed a clean installation (including using avastclear) of the latest avast version with the off-line installer ?

Try turn off port scan

Avast UI → Protection → Firewall → Settings → Advanced → Uncheck “Enable automatic port scan detection”

Any change?
