Just delete it then. Like Leigh said, it's just crap to scare Windows users into buying more crap.
If you're really worried about it then install clamav and a front end if you like (clamgtk, gnome or klamav, kde):
yum install clamav clamgtk
Besure to edit freshclam.conf and update the virus definitions:
Both clamgtk & klamav will then give you a pretty little gui. But it's primarily to protect your windows friends.
