If you installed from packages

• Find new packages and install them. See ClamPackages
• If there are no new packages, you have three options:
  • Wait
  • BuildClamPackage
  • InstallFromSource

If you installed from sources

• Uninstall the old version
• Compile and install the new one: see InstallFromSource

Note: Depending on your installation method, you might want to backup configuration (located in /usr/local/etc by default) and signature database (located in /usr/local/share/clamav by default). Don't forget to restore backups before starting up updated ClamAV.

Note: Backup your database signature (located in /usr/local/share/clamav by default) before upgrading to newer ClamAV version. Restore the backed up database signature before running the updated version. This is to avoid getting /usr/local/share/clamav not locked error message when doing freshclam.
