A subcategory of a security policy that pertains to computer viruses.

Software and technology that is used to detect malicious computer applications, prevent them from infecting a system, and clean files or applications that are infected with computer viruses. The Symantec Agent software works together with antivirus software. An Enforcer can check whether an Agent is running antivirus software, whether it is the correct version, and whether the current virus definitions (.dat files) are up-to-date. If the program or the .dat files are not current, an Enforcer can install the program, update the .dat files, and start it up. See also virus.
