URL:Blacklist

I am consistently getting a pop-up from my Avast software with the following threat, but I am completely unable to resolve it. It seems like a router issue since I am having the same thing occur on both my desktop and laptop, so I have rebooted the router (Linksys EA9500E) repeatedly to no avail.

If you look at the bottom of your screenshot

URL = The blocked URL (seems like a windows update URL … or is it fake?)

Process = Who is trying to connect to that URL

Report a false positive (select file or website)

Thanks for the information. How do I go about addressing it?

I gave you a link ... report it to avast lab and they will (should) give you a reply

Got it. Thanks!
