AntiVirus for Android appears to be blocking Play Store downloads

Hello Gail.
Thank you for reaching us here.
Apps downloaded from Google play store are verified, virus free apps and AVG usually does not interfere.
If I may ask, how did you narrow down this issue to AVG?

I have AVG AntiVirus for Android on my LG phone, but I can't download any apps from the Play Store. The downloads start, but never finish. Is there a setting I can change to allow the apps I choose to download?

Sure, Gail.

I request you to contact Google support for further assistance.

I didn't narrow it down to AVG, but it seemed logical that AVG might be blocking the downloads because I didn't have any issues with downloads before installing the latest version of AVG.
