im not a pro, but what i know is, Dont download mov files, dont download those files with a "NO ICON"-icon. And that is less then 10-60 kb, And becareful with porn downloads, is normally spam. I hate when it spams with some stupid antivirus,, just scan every file before opening it, thought i dont know if in some cases it can be to late, that it self-open,, dunno ,, gg
