This is, in fact, the main reason that antivirus software for Linux
exists. It is used mainly (but not excluseively) to scan for Windows
viruses.

The reason is quite simple - as Linux is still viewed by many as
exclusively server OS, something that will route your e-mail or store
your files on a network share, the data that is kept there or routed
trough is used primarily on Windows machines; therefore, an e-mail virus
scanner or a disk scanner that could scan Samba shares for files
infected with viruses that can't hurt Linux but can hurt Windows clients
isn't such a bad idea.

Another point is that Mac user can receive and send a file infected with
Windows virus without ever realizing that something isn't right. Not
that you should care if some Windows user send you infected document,
but you should take steps to ensure that it isn't you who is spreading
it further.
