AVG causes internet connectivity to be lost

I am using avg free 2017.
The avg icon on  the lower right taskbar on my desk top gets an "!" in the icon and I lose connectivity.
When I click the icon it says computer restart required, protection is off until I restart my computer, and you can't turn it back on, then suddenly the "!" vanishes  and internet is back on. This is around 30 min. intervals. No way am I going to restart my computer every 30 min.

Also avg web tune up keeps telling me to open my browser and allow the plug in to install. Why is this? I am using chrome and it does not work with chrome. Can I disable this message?
