Internet Security Blocking Internet

Hi
 I just loaded AVG Internet Security 20.10.3157 (build 20.10.5824.618)  and Tune Up.
For some reason, after an hour or so it blocks my internet.
I know it is this software as the wifi on my router and a second PC on the same router still have Internet connection. Also I turned off the software and the internet is fine. Please can you tell me how to stop it doing it.
