In every browser I use--Chrome, Firefox, and Internet Explorer--the same problem presents: I start typing and 2-3 characters in I automatically type in the search box. Additionally, my Windows search folder will periodically open on it's own and for the next minute or so rapidly flash as if I was re-opening it (won't allow me to close the folder at this point). This problem has been going on for months, but the browser search started before the windows search folder.
I've tried rebooting my computer, running virus checks, system registry checks...nothing seems to fix the problem. I'm hoping someone on here knows what's wrong before I do a last resort of a factory reset and/or zeroing out the hard drive.
