We recommend that you regularly download updates from the Trend Micro update server to ensure continued
protection. Trend Micro releases new virus pattern
files several times each week. The scan engine files, on the other hand, are updated
less
frequently.
After downloading updates from the Trend Micro
update server, you can designate a network drive to act as a download source (mirror)
for other
Information Servers on your network. This will avoid redundant downloads.
Downloading updates from a network drive is ideal for large networks (such as Intranets)
with
multiple Information Servers. Before attempting to download update files from another
server, you
must make sure the source server has the updated files.
