Installing from source

• Uninstall any old version: see UninstallClamAV (Note: this isn't essential, but removes sources of problems).
• wget the source gzip file: see WhichVersion
• untar the source to an appropriate location. Note that most modern versions of tar will automatically ungzip for you.
• ensure you have a user clamav and group clamav.
  • If you're using a different group/user you must specify that using the --with-user and/or --with-group option when you run configure
• Configure the build:
  • for clamav-milter support ./configure --enable-milter
  • to support new features ./configure --enable-experimental
  • otherwise ./configure
• run "make"
• if you did not uninstall the previous version, stop any running services.
• as root, run "make install" to install the binaries
• it is recommended that you run ldconfig as root after installing
• restart any relevant services.
• Run freshclam manually, to ensure your AV definitions are up to date.
