I will help you with the necessary information.

This can be caused by various reasons.

UDP port 53 is used for DNS - name resolution. AVG may query names for several of its services, and since we run many data centers all over the world, it may be more than just a few. If we are talking about UDP and port 53, these are most probably not connections/sessions, but just DNS requests.

Also this can be caused by component Fake website shield - more info for understanding here https://support.avg.com/SupportArticleView?l=en&urlname=Fake-Website-Shield-FAQs

Please provide us with more details, IP addresses, screenshots of the page where it shows that they are from AVG servers to investigate further.

My intrusion protection system has identified that something on my network is constantly (approximately 20 x per day) trying to contact various DNS servers on UDP Port 53. A quick Reverse DNS check shows they are all Avast servers. This lead me to AVG Internet Security being the culprit.

Two questions: -

1. Why is this occurring?
2. How do I stop it (other than constantly blocking IP Addresses and Ports using my IPS)?
