perl process keeps running after deletion

hi
i installed squirrelmail yesterday to test on a domain through install scripts.
then I removed the script again.

However the: perl /home/izihost.eu/public_html/webmail/config/conf.pl:
is still running and under "top: it takes 28% cpu

Under "files and permissions" it says: Current dir Directory 0 2753185 /home/izihost.eu/public_html/webmail/config (deleted)

How can a deleted script still be running and how can I prevent this from happening?

Also the cpu usage seems a little high. What if 20 users install squirrelmail?

thank you
