If Your Internet Browser open Without Your Clicking

If your PC or Laptop problem like this :

"The other day my browsers started opening two browser windows without my clicking for it too and when I close one of the browser windows, it closes both of them.
I've ran my virus security. Cleaned up the registry files. Updated windows and my browser. Updated my active-x. Reset my mouse settings for a slower speed and yet nothing seems to help... it appears to be getting worse.

I cannot figure this out.

I was wondering, if any of you all could suggest something that would be causing my pc issues.

I would greatly welcome any thoughts you may have on what this issue is and how I may can fix it. "
