On-Demand scan and its views
An on-demand scanner is a security scanner that you start manually at convenient times or regular intervals. It allows you to set various configurations and scan specific mails or mailboxes.
MSME enables you to create scheduled on-demand scans. You can create multiple schedules, each running automatically at predetermined intervals or times.
This feature is available only on an Exchange server that has Mailbox role. You cannot schedule an on-demand scan on an Exchange server that has only Edge Transport or Hub Transport role. |
When should you perform an on-demand scan
An on-demand scan is highly recommended if there is an outage in your organization due to malicious activity. This will make sure that the Microsoft Exchange databases are clean and are not infected during the outage.
McAfee recommends that you perform an on-demand scan task during non-business hours. When an on-demand scan task is scheduled during a non-business hour and it continues during peak work hours, you must reconsider the databases being scanned and create with alternate schedules by altering the data being scanned.
You can schedule an on-demand scan during the weekends to make sure that the Exchange Databases are clean and older emails are also scanned by the latest Anti-Virus signatures. Administrators must schedule an on-demand scan keeping in mind the number of Exchange servers, databases, and mail flow. Your goal must be to complete this task before business hours.
Why perform an on-demand scan?
You might want to perform an on-demand scan for a number of reasons. For example:
• | To check a specific file or files that has been uploaded or published. |
• | To check that the messages within your Microsoft Exchange server are virus-free, possibly following DAT update, so that new viruses can be detected. |
• | If you have detected and cleaned a virus and want to check that your computer is completely clean. |
