I like the idea of ClamWin, but unfortunately I cannot recommend it. I work with a lot of different malware, both new and old. In my experience, ClamWin has been one of the worst for detection.

If you want to check it for yourself, upload different malware to www.virustotal.com where they compare many different engines on the sample you provide.
