Repeated warning pop-up for doubleverify

I have been getting this same message on several of out computers for several days.  How can I stop this?  The message is the same for everyone.  I am the AVG adminstrator, so I get everyone's threat messages.

I keep getting a pop-up every few seconds that reads "We've blocked the threat URL:Mal on https://vast.doubleverify.com/v3/vast"? It's really annoying, and I'm not certain that what it's warning me about is an actual threat. Does anyone have any information on this?
