No, clamd does not give to transparent backgroup protection, like the Windows antivirus tools to. It is a daemonized version of clamscan, which means that it preloads the signature databases to memory, and scans the viruses in rapid manner when requested, as it does not need to reload the database again and again everyting like clamscan has to. Its purpose is speed up the scanning process. If you are familiar with SpamAssassin, clamd works like spamd in SpamAssassin. clamd sits resident in memory, and the client, clamdscan works as its client, passing the material to clamd to process. This is fast and efficient compared to plain clamscan. Saves resources and time needed to scan. _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://www.clamav.net/support/ml
