Hello Damon,
Apologies for the delay. My name is Jovana and I'm with AVG senior support.
Please note that virus definitions are updated regularly without notification in real-time by streaming updates.

Then the larger virus definitions package is delivered and visible in the application every once in a while.
You can also modify the auto-update value in the Geek area, as described here: https://support.avg.com/SupportArticleView?l=en&urlname=AVG-Antivirus-Geek-Area
I hope this clarifies and helps. If you need any further assistance or information feel free to write back
Enjoy your day!

Hello Damon,
We have escalated your request to concerned team. They will get back to as soon as possible.
When will AVAST/AVG internet security change the virus database checking from every 4 hours to every hour like bitdefender.
