Protect your Windows computers from security risks by installing the OfficeScan client on each computer. The client provides three methods of scanning: Real-time Scan, Scheduled Scan, and Manual Scan.
The client reports its status and events to the parent server in real time. Examples of events are security risk detection, client startup, client shutdown, start of a scan, or completion of an update.
There are two types of OfficeScan clients:
Normal clients maintain a continuous connection with the OfficeScan server.
Roaming clients are isolated from, and therefore cannot communicate with, the OfficeScan server. Users with roaming privilege may enable roaming mode when OfficeScan server intervention (such as server-initiated scanning) prevents them from fulfilling a task, such as when doing a presentation. Although communication with the server is lost, roaming clients with Internet connection can still update components if configured to get updates from an Update Agent or the Trend Micro ActiveUpdate server.
You should assign roaming privileges to clients that lose connection with the OfficeScan server for an extended period of time. Updates to roaming clients appear only on the following occasions:
When the client user performs manual update
When you configure automatic update deployment and include roaming clients to the clients that will update
When you grant clients the privilege to enable scheduled update
