Symantec seems to have a product:

Quote:
Symantec AntiVirus Command Line Scanner™ 1.0 provides advanced, high-performance virus scanning and repair services for Linux, Solaris and Windows based clients and servers. Symantec AntiVirus Command Line Scanner utilizes Symantec's CarrierScan Server™, which is based on Symantec's award-winning anti-virus technologies to detect malicious viruses, worms, and Trojan horses in all major file types, including mobile code and compressed file formats.
You've gotta be careful of the terminology. Very strictly speaking a virus is a piece of machine language code that is added into the free space at the end of the last page of an executable. It must be very tiny since free space is tight. Unix users rarely if ever download executables and there are many different machine languages, each with multiple executable formats. This makes unix based viruses very unprofitable.

But put some machine language in a gif file and you have a different situation. Unix users will download a gif file. Strictly speaking this is a trojan horse. But loosely, some folks will call this a virus. Or they talk about a gif file having a "viral content".

So a virus scanner on unix can make some sense provided that it doesn't take a real strict view of what constitutes a virus.

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
