You need anti-virus/anti-spyware mainly for people with whom you share files who run that Redmond OS, not RHEL. There is no anti-virus set up to catch Linux malware, because there hasn't been any need in the past or in the present. Most malware for Linux still requires user intervention to infect the Linux machine, or it only infects one user, not root.
