You don't need any antivirus if you don't have any virus.
If you want one anyway, use clamav.
yum install clamav
When virii are there, it's already too late.
You should use a pro-active aproach instead: don't use the internet as root, update your system with security updates often, don't open suspect emails and generaly don't do stupid things like giving your password on irc or posting your ip on a cracker forum and you should not need any antivirus.
Actually very few people use any antivirus on Fedora.
