For the past week or so, whenever I visit certain pages in IE (IE11), I get an ad that takes up the whole screen. I can't close the ad until a good 5-10 seconds later. Either I can let the ad load up and then close it, or click anywhere in the page and I will get an "Internet Explorer has stopped running due to a long-running script." I can click "Stop Script", which immediately loads up the ad and then I can close it.
I tried wiping out my internet history, cache, and cookies, to make sure nothing bad was in there, I did a full MBAM scan, and I even re-installed Adobe Flash.
Here is what the "ad" looks like while it is loading up. I can't close out of it during this process.
I also only get this on my laptop and not my desktop, both of which are running Windows 7 64-bit.
