I think no closed source software supports OpenMandriva (neither any distribution out of classical Red Hat/Centos, Debian/Ubuntu, sometimes SUSE). Generally they provide deb and rpm and sometimes a jar, a binary… See for example Kaspersky Endpoint Security for Linux
Only way to know is to buy (or download trial version) and test. There is an interesting document, about solutions on Linux, even if it maybe a little outdated (2015).
As I remember in the past I used Bitdefender Antivirus Scanner for Unices. I installed it on OMA 2014.1
But GUI crashed. CLI Worked. I contacted them. later they fixed it. I have done some tests for them on it too.
Bitdefender Antivirus Scanner for Unices does not work on OM Lx 3.0. Better contact them or you try it. I think they will provide a feedback
I think OMA should contact Antivirus companies (Paid and Free) and coordinate with them to provide a Good AV Certified to OpenMandriva Lx. As I remember In the Past Mandriva Promoted Kaspersky and Bitdefender.
Why promote binary only snake oil that likely contains more rootkits and security bugs than it fixes?
chkrootkit, rkhunter and clamav do their job and we can verify they actually do what they say they do and nothing else.
FI guess all depends of environment: in a small family with Linux only, clamav does its job. But in professional environment, sharing many files with Windows computers, a more efficient antivirus should be useful, at least to stop virus propagation.
