I am currently running SME 6.5, which I know is outdated and no longer supported. But I cannot upgrade until school lets out; many staff members depend on e-mail server right now. My ClamAV is outdated and can no longer get new virus defs, so I need to upgrade the engine. Can't do it by YUM, since 6.5 is no longer supported. I need step-by-step instructions on how to upgrade my ClamAV engine and then update the defs. Thanks in advance.
