For those of you who have installed Clamav, you may have noticed that there was a warning about a bug in bzip which mean that clamav couldn’t use it while scanning. With the 10.6.7 update the bug in bzip is no longer present. Apple in their wisdom did not update to the latest version of bzip, they instead fixed the bug in the currently installed version of bzip (1.0.5).

Now that the bug is fixed, clamav is able to use bzip. Unfortunately, for those of us who compiled and installed clamav before the 10.6.7 update, clamav needs to be recompiled and installed to do so.

Simply follow the updating instructions as though clamav 0.97 were an update and not a simply a rebuild.
Upgrading ClamAV.

There is no need to reconfigure anything.
