I have a link to a free program called "Ccleaner" below. you can set it up to delete cookies / history / temp files / recent typed urls / memory dumps , a bunch of shit. i`v bin using it for almost a year now with only good things to say about it. do your homework and read up on it. its free / fast and worth looking into.
