# The default virus scanner for Hydra::Works
# If ClamAV is present, it will be used to check for the presence of a virus. If ClamAV is not
# installed or otherwise not available to your application, Hydra::Works does no virus checking
# add assumes files have no viruses.
#
# To use a virus checker other than ClamAV:
# class MyScanner < Hydra::Works::VirusScanner
# def infected?
# my_result = Scanner.check_for_viruses(file)
# [return true or false]
# end
# end
#
# Then set Hydra::Works to use your scanner either in a config file or initializer:
# Hydra::Works.default_system_virus_scanner = MyScanner
module Hydra::Works
class VirusScanner
attr_reader :file
# @api public
# @param file [String]
def self.infected?(file)
new(file).infected?
end
def initialize(file)
@file = file
end
# Override this method to use your own virus checking software
# @return [Boolean]
def infected?
defined?(ClamAV) ? clam_av_scanner : null_scanner
end
def clam_av_scanner
scan_result = ClamAV.instance.method(:scanfile).call(file)
return false if scan_result == 0
warning "A virus was found in #{file}: #{scan_result}"
true
end
# Always return zero if there's nothing available to check for viruses. This means that
# we assume all files have no viruses because we can't conclusively say if they have or not.
