He pretty much nailed it ^^ but to add: if youre ever skeptical then right click and pick save target as. If it shows up as an html document its usually a link to some other crap. If it says zip or other file extension just read the save name. Usually it will say the name of the file you are downloading I.e. elite_body.pdo = good.....web_downloader.zip=some stupid browser add on or adware.
