why delete it? Just disable it and then you wont have to worry if it will break plesk

I trying to disable with /sbin/chkconfig drweb --level 345 off
when check the start status process with chkconfig --list | grep drweb is disabled to all modes, but when i make
/sbin/service psa start drweb is load again
Excuse my broken English
