SMART SCAN
• The smart scan client performs
scanning on the local computer.
• If the client cannot determine the
risk of the file during the scan, the
client verifies the risk by sending a
scan query to a smart protection
source.
• The client "caches" the scan query
result to improve the scan
performance.

Default Scan Method
In this OfficeScan version, the default scan method for fresh installations is smart scan.
This means that if you perform OfficeScan server fresh installation and did not change
the scan method on the web console, all clients that the server manages will use smart
scan.
If you upgrade the OfficeScan server from an earlier version and automatic client
upgrade is enabled, all clients managed by the server will still use the scan method
configured before the upgrade. For example, upgrading from OfficeScan 8.x, which only
supports conventional scan, means that all clients will still use conventional scan upon
upgrade. If you upgrade from OfficeScan 10, which supports smart scan and
conventional scan, all upgraded clients that use smart scan will continue to use smart
scan and all clients using conventional scan will continue to use conventional scan.
