Setting up scheduled scans that run on Windows computers
You configure scheduled scans as part of a Virus and Spyware Protection policy.
Consider the following important points when you set up a scheduled scan for the Windows computers in your security network:
Multiple simultaneous scans run serially
If you schedule multiple scans to occur on the same computer and the scans start at the same time, the scans run serially. After one scan finishes, another scan starts. For example, you might schedule three separate scans on your computer to occur at 1:00 P.M. Each scan scans a different drive. One scan scans drive C. Another scan scans drive D. Another scan scans drive E. In this example, a better solution is to create one scheduled scan that scans drives C, D, and E.
Missed scheduled scans might not run
If your computer misses a scheduled scan for some reason, by default
Symantec Endpoint Protectiontries to perform the scan until it starts or until a specific time interval expires. If
Symantec Endpoint Protectioncannot start the missed scan within the retry interval, it does not run the scan.
Scheduled scan time might drift
Symantec Endpoint Protectionmight not use the scheduled time if the last run of the scan occurred at a different time because of the scan duration or missed scheduled scan settings. For example, you might configure a weekly scan to run every Sunday at midnight and a retry interval of one day. If the computer misses the scan and starts up on Monday at 6 A.M., the scan runs at 6 A.M. The next scan is performed one week from Monday at 6 A.M. rather than the next Sunday at midnight.
If you did not restart your computer until Tuesday at 6 A.M., which is two days late and exceeds the retry interval,
Symantec Endpoint Protectiondoes not retry the scan. It waits until the next Sunday at midnight to try to run the scan.
In either case, if you randomize the scan start time you might change the last run time of the scan.
Windows settings include some options that are not available for clients that run on other operating systems.
