Jesuis, for your poor kazaa performance due to a low file count,
just make a blank notepad/text file, and duplicate it, then duplicate the two of them, then duplicate the four, then duplicate the eight...etc.
It's a slow process to begin with, but gets quicker and quicker, with more and more files being created.

Now when you have around 4000 of these empty files (I only reccomend blank notepad files, as they are the smallest kind I know how to make, so they don't actually take up much space.)

Put these duplicated files into your "shared" folder, and there you go, it fools kazaa into thinking you have that many files shared, and you get more searches, more results, and HEAPS faster d/ls.
Just a little trick I figured might work, and hey, it did...

I'd reccomend anti-spyware programs to be run after every use (kazaa) though, as vamp said, spyware s&d is a pretty good one.
