IANAWU, but what about the team of ClamWin and Winpooch? ([1]_, [2]_)
ClamWin is the Windows GUI to ClamAntivirus, and Winpooch is the
real-time file monitor that enables clamwin to scan files as they are
accessed, modified, or created.

Add in Spybot-S&D[3]_, and you should have a killer team against SPAM,
viruses, trojans and spyware!
