clamav update advice

[Rodney Green]

Hello,
I'm looking at upgrading ClamAV to version 0.90.1; I'm currently
running version 0.88.4 which was installed using Julian's install
package.
The instructions for 0.90.1 says that I have to uninstall the previous
version. I've attempted to run "make uninstall" from the source
directory for 0.88.4, but I'm getting a "No rule to make target
'uninstall'" error. How can I uninstall the previous version? Any
advice is welcome. :-)

Thanks,
Rod
