Following our previous report on problems with ClamXav and Snow Leopard, it appears the developer has released a new version addresses these issues. Version 2.0.2 brings back contextual menu support, custom folder analysis, and application hangs.
The update is available from the ClamXav website and in addition to bug fixes, adds support for the new Snow Leopard "Services" menu. If you are a ClamXav user and have updated to Snow Leopard, we highly recommend you apply this latest update.
