Looking for an AV solution to use in a mixed environment.

Hi everyone

I was hoping a few of you have been in a similar situation and could make some suggestions.

I have a mixed workstation environment with Ubuntu and Windows 7. At the moment only the Windows 7 machines have AV on them, controlled by a management station.

Can anyone recommend a solution that will allow an AV management server (preferably running on Linux) to manage AV on both Windows and Ubuntu.

[and before anyone says, yes we do need AV on the linux workstations :) We need to make sure that we do not end up passing on potentially infected documents to others]
