I use IE 10, Firefox, and Chrome. They all have pluses and minuses. They all have been 'exploited' (indeed any useful system will get parasitized, sooner or later) for nefarious purposes. My own experience with IE 10 is that web sites that are good with HTML 5 and related standards works just fine under IE 10, unless they have lots of specialized, hmm, er, hacks needed to be viewed in older IE versions or deal with some kinds of 'active' content that costs too much to be redone to current HTML5 and related standards.
