Might have deleted javascript and adobe flash player
I tried to delete unnecessary files in my drive c so that I can have more space in my hardisk because it's getting slow.I didn't quiet notice that in the deletion that I did,I might have affected the javascript and the adobe flash player.coz every time I visited site that offer videos,the site would either say " that i might have turned off my javascript "or "i have to install my adobe flash player".I really don't know what to do.I have already successfully downloaded adobe flash player myself few times but it still don't work .
