Hi Bonno,
Don't know if there was a howto, now there is one :-)
there are two compilations of Clam on Windows, ClamWin and SOSDG ClamAV.
(http://www.sosdg.org/clamav-win32)
I think both are running stable at the moment, but I'm not sure (ClamAV was not
really stable about a year or two ago)
I've been using the SOSDG version of ClamAV (http://www.sosdg.org/clamav-win32)
with no problem. The is the same version/port of ClamAV that SmarterMail ships
with their product.
The trick is setting it up to run as a service with runclamscan and runclamd.
These are included with ClamAV in
