DESCRIPTION

This class provides a common API for scanning files or directories with one or more third party virus scanners.

Virus scanners are supported via pluggable engines under the File::VirusScan::Engine namespace. At the time of this release, the following plugins are shipped with File::VirusScan:

Clam Antivirus

Scanning daemon via File::VirusScan::Engine::Daemon::ClamAV::Clamd, and commandline scanner via File::VirusScan::Engine::Command::ClamAV::Clamscan

NAI UVScan

File::VirusScan::Engine::Command::NAI::Uvscan

F-Secure FSAV

File::VirusScan::Engine::Command::FSecure::FSAV

Trend Micro

Scanning daemon via File::VirusScan::Engine::Daemon::Trend::Trophie, commandline scanning via File::VirusScan::Engine::Command::Trend::Vscan

BitDefender BDC

File::VirusScan::Engine::Command::BitDefender::BDC

Command Antivirus

File::VirusScan::Engine::Command::Authentium::CommandAntivirus

Norman Antivirus

File::VirusScan::Engine::Command::Norman::NVCC

ESET

Scanning via esets_cli with File::VirusScan::Engine::Command::ESET::NOD32

Symantec

Scanning via Carrier Scan server with File::VirusScan::Engine::Daemon::Symantec::CSS

F-PROT

Scanning daemon via File::VirusScan::Engine::Daemon::FPROT::V4 and File::VirusScan::Engine::Daemon::FPROT::V6, as well as the commandline scanners via File::VirusScan::Engine::Command::FPROT::FPROT and File::VirusScan::Engine::Command::FPROT::Fpscan

Central Command Vexira

File::VirusScan::Engine::Command::CentralCommand::Vexira

Sophos

Daemonized scanning using the Sophie daemon with File::VirusScan::Engine::Daemon::Sophos::Sophie. Commandline scanning with File::VirusScan::Engine::Command::Sophos::Sweep or File::VirusScan::Engine::Command::Sophos::Savscan

Kaspersky

Scanning with aveserver using File::VirusScan::Engine::Command::Kaspersky::AVP5, or with kavscanner using File::VirusScan::Engine::Command::Kaspersky::Kavscanner

METHODS

new ( { config data } )

Creates a new File::VirusScan object, using configuration data in the provided hashref.

Required configuration options are:

engines

Reference to hash of backend virus scan engines to be used, and their specific configurations.

Keys must refer to a class that implements the File::VirusScan::Engine interface, and may be specified as either:

1. A fully-qualified class name.

2. A name beginning with '-', in which case the '-' is removed and replaced with the File::VirusScan::Engine:: prefix.

Values should be another hash reference containing engine-specific configuration. This will vary by backend, but generally requires at minimum some way of locating (socket path, host/port) or executing (path to executable) the scanner.

Optional configuration options are:

order

List reference containing keys provided to engines above, in the order in which they should be called.

If omitted, backends will be invoked in hash key order.

always_scan

By default, File::VirusScan will stop scanning a message after one backend finds a virus. If you wish to run all backends anyway, set this option to a true value.

scan ( $path )

Invokes the configured scan backends on the path. The path may be either a single file, or a directory.

Returns an File::VirusScan::ResultSet object, which can be queried for status.

get_backends ( )

Returns a reference to the internal array of configured backend instances.

DEPENDENCIES

File::VirusScan::Engine, File::VirusScan::Result
