The site im curently on is aD ofcourse and the site advisor is green meaning that the site is safe. ok now say if a newbie search's for the unmentionable "cracks" or "keygens" (which you should never ever do, unless your a idiot this is what the site advisor will tell you. this is what youll get. you can click the site advisor icon and select "veiw site details" for more info. and youll be taken to a page containg the sites analysis,heres what i got from google. i think this is a great add on, if anyone else knows any good ones then post them here. the link for this again is: http://www.download.com/SiteAdvisor-for-Firefox/3000-2378_4-10493670.html?tag=fmr_title
