Scan Methods

OfficeScan can use either conventional scan or smart scan when scanning for viruses/malware.

Conventional Scan

Conventional scan is the scan method used in all earlier OfficeScan versions. A conventional scan client stores all OfficeScan components on the client computer and scans all files locally.

Smart Scan

Smart scan is a next-generation, in-the-cloud based endpoint protection solution. At the core of this solution is an advanced scanning architecture that leverages threat signatures that are stored in-the-cloud.

Scanning behavior

The conventional scan client performs scanning on the local computer.

  • 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.
