My Windows 10 PCs on my Deco network are having trouble getting updates, including the definition updates for defender. When I try to download the updates manually I get a parental controls restriction that says the site is classified as "Microsoft Windows Update, Pay to Surf" [emphasis mine]
If I look at Trend Micro Site Safety Center (where the Deco database is from) the URL is classified as "Computers / Internet" so it seems there is somthing wrong with the Deco...
I know I can work around the problem by changing the parental controls settings (and I will, to get things going) But I'd like to know what is going wrong with the Deco such that it is getting false positives like this! Of course I worry more about false negatives, but one bug could do both!
The URL I'm using as an example here is: http://definitionupdates.microsoft.com/download/DefinitionUpdates/VersionedSignatures/AM/1.305.1426.0/amd64/mpam-fe.exe
(also available as https, but you can't see the block reason when TLS is involved...)
