Update malicious code protection mechanisms when new releases are available.

Malware changes on an hourly or daily basis, and it is important to update detection and protection mechanisms frequently to maintain the effectiveness of the protection. In general, anti-malware software compares a file against a signature database to decide if the file is malicious. For anti-malware software to be effective the signature database must remain updated. If the signature database is outdated then it can not detect new malware.

Configure your anti-malware software to update its malware signature database. The updates should be periodic (e.g., every day at 8:00 AM) or automatic when a new update is availble.
