If you want to check files or directories for a Windows virus before passing it on to a Windows user you can do it online with the Java app at Trend Micro HouseCall.
I can also recommend Virus Total http://www.virustotal.com/en/indexf.html, which scans an executable through a dozen different vendor AV products.
