Command to display freshclam
manual in Linux: $ man 5 freshclam
The service is called clamav-daemon.service.Start it and enable it to start at boot. Testing the software. In order to make sure ClamAV and the definitions are installed correctly, scan the EICAR test file (a harmless signature with no virus code) with clamscan. Since there is no native MacOS build for ClamAV, we need to first install a mechanism to package ClamAV for installation onto MacOS. We will use MacPorts for this procedure. Install MacPorts and PreRequisites. Install Xcode from the Mac App Store: Launch the Mac App Store by clicking the 'App Store' menu item from the Apple menu. I think it's a mistake to not create at leat man page for clamav, wich is the name of the package. – m3nda Jun 23 '15 at 3:06 7 If you want to check all files of the system, then you should use clamscan -r -bell -i -exclude-dir='^/sys' / because in /sys/ are no real files and not excluing it would cause reading errors.
NAME
freshclam.conf - Configuration file for Clam AntiVirus database update tool
DESCRIPTION
The file freshclam.conf configures the Clam AntiVirus Database Updater, freshclam(1).
FILE FORMAT
The file consists of comments and options with arguments. Each line which starts with a hash (#) symbol is ignored by the parser. Options and arguments are case sensitive and of the form Option Argument. The arguments are of the following types:- NUMBER
- Unsigned integer.
DIRECTIVES

When an option is not used (hashed or doesn't exist in the configuration file) freshclam takes a default action.
- Default: LOG_LOCAL6
- PidFile STRING
- This option allows you to save the process identifier of the daemon to a file specified in the argument.
Default: disabled - LogVerbose BOOL
- Enable verbose logging.
Default: disabled - DNSDatabaseInfo STRING
- This directive enables database and software version checks through DNS TXT records.
Default: enabled, pointing to current.cvd.clamav.net - DatabaseMirror STRING
- Server name where database updates are downloaded from. In order to download the database from the closest mirror you should configure freshclam to use db.xy.clamav.net where xy represents your country code. If this option is given multiple times, freshclam(1) tries them in the order given. It's strongly recommended that you use db.xy.clamav.net as the first mirror and database.clamav.net as the second.
Default: database.clamav.net - MaxAttempts NUMBER
- How many attempts (per mirror) to make before giving up.
Default: 3 (per mirror) - ScriptedUpdates BOOL
- With this option you can control scripted updates. It's highly recommended to keep it enabled.
Default: enabled - CompressLocalDatabase BOOL
- By default freshclam will keep the local databases (.cld) uncompressed to make their handling faster. With this option you can enable the compression; the change will take effect with the next database update.
Default: no - HTTPProxyServer STR, HTTPProxyPort NUMBER
- Use given proxy server and TCP port for database downloads.
- HTTPProxyUsername STR,HTTPProxyPassword STRING
- Proxy usage is authenticated through given username and password.
Default: no proxy authentication - HTTPUserAgent STRING
- If your servers are behind a firewall/proxy which applies User-Agent filtering, you can use this option to force the use of a different User-Agent header.
Default: clamav/version_number - LocalIPAddress IP
- Use IP as client address for downloading databases. Useful for multi homed systems.
Default: Use OS'es default outgoing IP address. - NotifyClamd STRING
- Notify a running clamd(8) to reload its database after a download has occurred. The path for clamd.conf file must be provided.
Default: The default is to not notify clamd. See clamd.conf(5)'s option SelfCheck for how clamd(8) handles database updates in this case. - OnUpdateExecute STRING
- Execute this command after the database has been successfully updated.
Default: disabled - OnOutdatedExecute STRING
- Execute this command when freshclam reports outdated version. In the command string %v will be replaced by the new version number.
Default: disabled - OnErrorExecute STRING
- Execute this command after a database update has failed.
Default: disabled - ConnectTimeout NUMBER
- Timeout in seconds when connecting to database server.
Default: 10 - ReceiveTimeout NUMBER
- Timeout in seconds when reading from database server.
Default: 30 - SubmitDetectionStats STRING
- When enabled freshclam will submit statistics to the ClamAV Project about the latest virus detections in your environment. The ClamAV maintainers will then use this data to determine what types of malware are the most detected in the field and in what geographic area they are. This feature requires LogTime and LogFile to be enabled in clamd.conf. The path for clamd.conf file must be provided.
Default: disabled - DetectionStatsCountry STRING
- Country of origin of malware/detection statistics (for statistical purposes only). The statistics collector at ClamAV.net will look up your IP address to determine the geographical origin of the malware reported by your installation. If this installation is mainly used to scan data which comes from a different location, please enable this option and enter a two-letter code (see http://www.iana.org/domains/root/db/) of the country of origin.
Default: disabled

How Good Is Clamav
The current version works in a passive mode only - ClamAV will log the detection but won't block access to the infected file. However, it's possible to perform special actions (eg. quarantine files) with the VirusEvent directive of clamd.
Usage
-----
1. Run ClamAuth_load to load the kernel extension (you can edit the script to change or add more paths that will be monitored).
2. Add 'ClamAuth yes' to your clamd.conf (ClamAV 0.97.4) or 'ScanOnAccess yes' (ClamAV-devel)
3. Start clamd with root privileges ('sudo /usr/local/sbin/clamd')
If clamd properly connects to the driver, you should see a line like this in the log file:
ClamAuth: Driver version: 0.3, protocol version: 2

ClamAV is now monitoring the paths specified in ClamAuth_load.
