It is a program for locating files quickly and easily.  That
slocate.cron was probably in something like /etc/cron.daily, in which it
gets run sometime during the night and builds the database of all the
files on your system.  Then when you need to find something, just run
"locate passwd" and in mere seconds you have your answer.

But it shouldn't be running every time you log on, unless you mean when
you boot into Linux.  There may be some code in the startup scripts to
run once on bootup, but then you'd have to hunt down in /etc/rc.d for
the file that calls it...
