Clamscan is a command line anti-virus scanner which scan files and directories for viruses. clamdscan is a Clam AntiVirus Daemon which also scan files and directories for viruses using same database and definition. It is a simple clamd client which may be used as a clamscan replacement. It accepts all the options implemented in clamscan but most of them will be ignored because its scanning abilities only depend on clamd. The clamd daemon listens for incoming connections on Unix and/or TCP socket and scans files or directories on demand. It reads the configuration from /etc/clamd.conf
