If you see the warning WARNING: Your ClamAV installation is OUTDATED! - this sounds more dramatic than it actually is, and it is usually not necessary to take any action. This just means that a newer ClamAV version is available than the one that is installed - your current version is still ok. It does not mean that the virus signature database is not up to date - it actually is, and protection is still guaranteed.
