Avast restore settings when i reboot the PC

Hi all,

I am having a problem with Avast version 8.0.1609. I was trying to fix an issue with yellow exclamation mark on network adaptor and when i tried to follow steps from this forum changing settings in order to resolve this issue i found another issue. Basically everytime i change any setting, after reboot the default setting come back.

I have tried to change the password but even the password goes to default too.

Someone else experienced this problem?

Regards.
