Configure the Security Server to regularly check its update source and automatically download any available updates. Using scheduled update is an easy and effective way of ensuring that protection against threats is always current.
During times of virus/malware outbreaks, Trend Micro responds quickly to update virus pattern files (updates can be issued more than once each week). The scan engine and other components are also updated regularly. Trend Micro recommends updating your components daily, or even more frequently in times of virus/malware outbreaks, to help ensure the agent has the most up-to-date components.
Important:
Avoid scheduling a scan and an update to run at the same time. This may cause the Scheduled Scan to stop unexpectedly.
