Hi...
There are a growing number of other 'file sizes' that are definite giveaways as being total dangerous crap.
Only a few years ago there were only two or three of them and they were almost always 'dialers'.
The other good ones, LOL, are the 'torrent' files that are like 3,486 (or whatever) Kb... That's one mother of a torrent file size, eh ?
Best way to find them is to do a search for anything nonsensical... your name spelled backwards works a treat !
britney pastrami rye has also been most effective !
Give it some time and 'push' the search a few times...
Bingo... Crap file sizes galore !
Write them down... Hey, scratch them into your monitor and never D/L anything of the same size... Even if there are 983 Sources !
