Windows virus scanner for Samba shares?

[Jeremy C. Reed]

Any of you run a Windows virus scanner on your Linux box to scan Samba 
shares?

If so, what do you use? Do you have commercial updates and costs?

I see clamav, F-Prot Antivirus, commercial uvscan. And I am currently 
doing research. I have worked with some antivirus solutions for email 
filtering. But in this case, I need to scan directories of files, which 
will also probably involve extracting archives.

In addition to running anti-virus on the Linux file server, now an 
off-topic/Windows question: any suggestions for anti-virus software to 
install on the Windows Xp and 2000 machines themselves? My customer is 
using some version of Symantec Norton antivirus.

I'd like to be able to setup the Windows boxes to share the same 
downloaded signature (keep on the Linux samba server). What small office 
solutions do you use?
