viruses per se, don't really apply to unix (there are trojan horses, etc, that can do a great deal of damage though).

here is some snippet from a pdf found on the above site:

" The UNIX operating system is a secure environment, relatively unaffected by computer viruses. The DOS and Windows environment, however, is different. DOS computers have no security and are very susceptible to virus infections. Because DOS system viruses don't affect UNIX systems, you might ask: “Why
should I be concerned?”

One reason for concern is that DOS- and Windows-based computers are rapidly appearing on the Internet-and most of these computers use the Internet for file transfer. A UNIX server might still harbor DOS system viruses and, while not itself affected, can pass them on to numerous DOS- and Windows-based clients. Rather than trying to block viruses at each DOS- and Windows-based computer connected to a UNIX system, you can install the VirusScan for UNIX software and use it as an efficient centralized solution. "

Cheers!
Vishnu.

NAME
clamdscan - scan files and directories for viruses using Clam AntiVirus Daemon SYNOPSIS
clamdscan [options] [file/directory] DESCRIPTION
clamdscan is a 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. OPTIONS
-h, --help Display help information and exit. -V, --version Print version number and exit. -v, --verbose Be verbose. --quiet Be quiet - only output error messages. --stdout Write all messages (except for libclamav output) to the standard output (stdout). --config-file=FILE Read clamd settings from FILE. -l FILE, --log=FILE Save the scan report to FILE. -f FILE, --file-list=FILE Scan files listed line by line in FILE. -m, --multiscan In the multiscan mode clamd will attempt to scan the directory contents in parallel using available threads. This option is espe- cially useful on multiprocessor and multi-core systems. If you pass more than one file or directory in the command line, they are put in a queue and sent to clamd individually. This means, that single files are always scanned by a single thread. Similarly, clamdscan will wait for clamd to finish a directory scan (performed in multiscan mode) before sending request to scan another direc- tory. This option can be combined with --fdpass (see below). --remove Remove infected files. Be careful. --move=DIRECTORY Move infected files into DIRECTORY. --no-summary Do not display summary at the end of scanning. --reload Request clamd to reload virus database. --fdpass Pass the file descriptor permissions to clamd. This is useful if clamd is running as a different user as it is faster than streaming the file to clamd. Only available if connected to clamd via local(unix) socket. --stream Forces file streaming to clamd. This is generally not needed as clamdscan detects automatically if streaming is required. This option only exists for debugging and testing purposes, in all other cases --fdpass is preferred. EXAMPLES
(0) To scan a one file: clamdscan file (1) To scan a current working directory: clamdscan (2) To scan all files in /home: clamdscan /home (3) To scan a file when clamd is running as a different user: clamdscan --fdpass ~/downloads (4) To scan from standard input: clamdscan - <file_to_scan cat file_to_scan | clamdscan - RETURN CODES
0 : No virus found. 1 : Virus(es) found. 2 : An error occured. CREDITS
