Clamuko

Clamuko is a special thread in clamd that performs on-access scanning under Linux and FreeBSD and shares internal virus database with the daemon. You must follow some important rules when using it:

• Always stop the daemon cleanly - using the SHUTDOWN command or the
  SIGTERM signal. In other case you can lose an access to protected files until the system is restarted.
• Never protect a directory your mail-scanner software uses for attachment unpacking. Access to all infected files will be automatically blocked and the scanner (even clamd) won't be able to detect any virus. In the result all infected mails will be delivered.

For example, to protect a whole system add the following lines to clamd.conf:

	ClamukoScanOnAccess
	ClamukoIncludePath /
	ClamukoExcludePath /proc
	ClamukoExcludePath /temporary/dir/of/your/mail/scanning/software

You can also use clamuko to protect files on Samba/Netatalk but far more better and safe idea is to use the samba-vscan module (see 8.14). NFS is not supported because Dazuko doesn't intercept NFS access calls.
