3. How OfficeScan protect my system from security risks?

Real-time Scan
OfficeScan scans files in real time. If OfficeScan detects no security risk, users can proceed to open or save the file. If OfficeScan detects a security risk, it displays a notification message, showing the name of the file and the specific security risk.

Manual Scan
Manual Scan for virus/malware starts immediately after a user launches it in the client console. The length of the scan depends on the number of files to scan and the client computer’s hardware resources.

The scan time and coverage for spyware/grayware depends on the scan method you or the administrator has set. You can configure scan method if the administrator grants you this privilege.

Scheduled Scan
Scheduled Scan has similar scan behavior as Manual Scan. The only difference is that Scheduled Scan runs automatically on the scheduled date and time. Use Scheduled Scan to automate routine scans on the client and improve scan management efficiency.
