The ClamAV developers have announced that the 15th of April 2010 will be the end-of-life (EOL) date for all versions up to 0.94.x of their free open source anti-virus program. The reason for the change is that releases older than 0.95 are affected by a bug in freshclam, the ClamAV utility used to download new virus definitions. The bug prevents incremental updates from working with signatures that are longer than 980 bytes. The developers note that they haven't yet released any signatures that exceed the limit.
