Sounds like skinner sold out to the advertisers. Only the worst of sites automatically pop up the ad-store.
I'm glad you clarified. I've used this laptop since 2010, and a Nook tablet and a Galaxy Tab (both use versions of Android) and have never seen anything like what she described. I was almost wondering if it was some sort of security hole in iOS, but Mrs. SVPete and one of my daughters have iPads, and they've never complained of anything similar.
There are a couple of conservative news/commentary sites - PJMedia and Breitbart - whose ads do obnoxious stuff, but, again, not anything like what she described. I guess going to "right" websites isn't going to the right websites.
That assumes she is describing her "issue" accurately.
