uncatergoized site pop up
when using the internet on my dughters account only (not mine!) I( keep getting a notification from norton that the computer is trying to connect to an uncatergorized site, even when I'm not clicking on anyting. THe site is ak.apnstatic.com
I vannot find what this site is anywhere, or why my computer is trying to access it. I've done a full scan and no viruses or threats are found.
Any ideas please?
