When you go to certain web sites ( ABC.com video clips for example ) the ACTIVE X FILTER installed in IE 10 and IE 11 will block the video content. When it does, the web site ( ABC.com ) thinks you don't have Flash Player installed and offers to intall it for you. DO NOT use the TOOLS menu of IE to turn off ACTIVE X FILTERING. That will make you vulnerable to the malicious applets that the filter was disigned to protect you against.
Find the ADDRESS box on the top left of the IE browser page ( where http://forums.adobe.com appears ). On the far right of the box is a clockwise circular arrow that will REFRESH your current page. Immediately to the left of the REFRESH arrow is a small circle with a diagonal line thru it ( the universal symbol for negation as in NO LEFT TURN traffic sign ). Left click on the small circle and then click on the TURN OFF ACTIVE X FILTERING button that appears in the drop down box. I believe that will turn off the filtering for this one web page and for this visit only. That should solve your problem.
You're likely infected with "adware". A maliscious file is trying to persuade you to download a "fake" update containing more malware. (A screenshot of the popup would better help to determine this, though)
Run a thorough virus scan. Also download TDSSKiller from Kaspersky. It'll usually find and remove the offending beast even if your Antivirus won't.
Thanks Mike, I downloaded your suggestion, it did cleanup 10 threats that I had. We will see how it works out, thanks a lot and Happy Thanksgiving to you,
