I defined what the IP address is in my thread…

The IP address in my screenshot is:
http://208.91.196.4/?dn=enhancedprivacy.eu&pid=7PO84Q7C6

If you go into the Privacy list addons in IE > Get more tracking lists > click on Enhanced Privacy List, this particular privacy list’s URL is (as listed on Microsoft):
http://www.searchremagnified.com/?dn=enhancedprivacy.eu&pid=7PO84Q7C6

Per http://netiplist.com/domain/searchremagnified.com
searchremagnified = 208.91.196.4 in the British Virgin Islands

The Avast pop ups can be stopped by going into IE11 > manage add ons > tracking protection > and removing the enhanced eu item (wont work if you just disable it you have to remove it).

The only real question on this is… is it normal for tracking lists to call home while surfing (which it would have to be because they need to update) and/or did something occur with the website to cause this… As far as I can tell since it’s a tracking list trusted by Microsoft my first inclination is that is a FP by Avast.

Either way it’s not a virus on the OP’s, or my, computers. It’s an Avast / Enhanced EU Website issue.
