Printer doesn't work after AVG renewal

I renewed AVG Internet Security Last November 2020.  My Brother printer has not worked since.  Printer shows WiFi connection and computer has connection.   But computer says it cannot connect. What do I need to do or change?  Help please.  Thank you in advance.

Hi, Diana

We will help you in this. 
How did you figure out that AVG is blocking the printer?
Do you recevie any notifcations from the AVG when you try to use the printer?
