does NOD32 3.0 work on Linux OS?

I have client who currently has NOD32 3.0 installed. The client is fed up with Windows and was going to switch to a Linux OS, he was wondering if NOD32 will work on Linux. I know there is NOD32 for the Linux Server, but wasn't sure on a Linux OS. I already contacted ESET but havent yet heard a reply back, and given that I don't want to have to make the client wait around, I figured I would ask here, I'm sure someone knows/has tried already.

 

I guess your client needs ESET File Security:

But have no idea if he can purchase license for 1 machine only
