Having All kinds of problems with IE 11

I am not sure when it happened and I have found no way to fix IE 11.

I have www.yahoo.com set as my home page, but when I try to open IE, it goes to a page with no address and I have to type in yahoo to get that to open.

Also each time I change a page, this popup occurs causing the page to lock up until I close the popup:

Dang it will NOT even let me upload the image now, but it a search screen and it locks the page until I close it. When I do close it, usually another website open (usually a porn site).

Other than that my PC is running fine. I really do NOT want to have to reinstall Windows to fix this problem. Any help would be greatly appreciated.

I am having all kinds of issues with IE.

I believe some are caused by Java. On some sites it indicates that Java is blocking some things on that particular site.

I am also getting this popup when I open IE.



How do I stop this from happening?

When I select Allow or Do not Allow I get a blank page and have to either type in the site I want or use my Favorites to go the the site I want. This is a real bitch.

I really need to fix this, but HOW?

If I can get these two problems fixed, it would be a great help. Thank you.
