Edit crontab file

[Negahrev]

Hi,

I'm receiving a lot of emails from my cron.hourly proces that an file cannot be found.
In my crontab file there are the following lines at the bottom:

#
*/3 * * * * root /etc/cron.hourly/gcc.sh

gcc.sh is very likely a virus.

But when i do 'crontab -e' the record is not visible,
I cant edit the crontab file itself.

How do I get rid of this record?

Thanks in advance.
