3 different computers with the same "blocked by PUA blacklist" warning

[mtellefson 0]

I have 3 different computers that have web protection warnings because Chrome is trying to access my.rtmark.net.  One computer had 4 occurrences over 6 days and the other 2 each had two occurrences within the same day.  How likely is it that they all clicked the same/similar bad links or fell for a link in an email?  Should I be looking for some malware acting behind the scenes?

The domain is ad-related so I assume the users merely went to a website that loaded ads from the blocked one. It should be safe to ignore it.

That makes sense.  Thanks Marcos.
