Virus protection for MJ lists?

[David Gibbs <david @ midrange . com>]

Hi!

Can anyone recommend a good virus protection product for use with
MJ lists under Linux (2.0.36 kernel)?

A number of my subscribers have taken to attaching ms word docs
to mailing lists ... and some of them are turning up with viruses.

I'd like to protect the rest of my subscribers from the mistakes of
others.

Thanks!
