Description
Antivirus software should be installed as soon after OS installation as possible and then updated with the latest signatures and antivirus software patches (to eliminate any known vulnerabilities in the antivirus software itself). The antivirus software should then perform a complete scan of the host to identify any potential infections. To support the security of the host, the antivirus software should be configured and maintained properly so it continues to be effective at detecting and stopping malware. Antivirus software is most effective when its signatures are fully up-to-date. Accordingly, antivirus software should be kept current with the latest signature and software updates to improve malware detection. The scan cache retains files previously scanned and determined to be clean. Since a cache scan result is not invalidated when a new antivirus signature (DAT) is received, and a cached file will only be re-scanned after the cached result expires, caching files past a 24 hour period allows for newly discovered malware to go undetected in those cached files. Cached files should expire after no more than 24 hours in order to be scanned with new antivirus signatures every day.
