A scheduled scan on the Symantec Endpoint Protection client is an important component of threat and security risk protection. You should schedule a scan to run at least one time each week to ensure that your computer remains free of viruses and security risks. When you create a new scan, the scan appears in the scan list in the Scan for threats pane.
If your administrator has created a scheduled scan for you, it appears in the scan list in the Scan for threats pane.
Your computer must be turned on and Symantec Endpoint Protection Services must be loaded when the scan is scheduled to take place. By default, Symantec Endpoint Protection Services are loaded when you start your computer.
For managed clients, the administrator may override these settings.
Consider the following important points when you set up a scheduled scan:
User-defined scans do not require the user to be logged in
If the user who defined a scan is not logged in, Symantec Endpoint Protection runs the scan anyway. You can specify that the client does not run the scan if the user is logged off.
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 Protection tries to perform the scan until it starts or until a specific time interval expires. If Symantec Endpoint Protection cannot start the missed scan within the retry interval, it does not run the scan.
Scheduled scan time might drift
Symantec Endpoint Protection might 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 6am, the scan runs at 6am. The next scan is performed one week from Monday at 6am rather than the next Sunday at midnight.
If you did not restart your computer until Tuesday at 6am, which is two days late and exceeds the retry interval, Symantec Endpoint Protection does 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.
You can also create an on-demand or startup scan.
To schedule a user-defined scan
In the client, in the sidebar, click Scan for threats.
Click Create a New Scan.
In the Create New Scan - What To Scan dialog box, select one of the following types of scans to schedule:
Scans the areas of the computer that viruses and security risks most commonly infect.
You should run an active scan every day.
Scans the entire computer for viruses and security risks.
You might want to run a full scan once a week or once a month. Full scans might affect your computer performance.
Scans the selected areas of the computer for viruses and security risks.
If you selected Custom Scan, check the appropriate check boxes to specify where to scan, and then click Next.
The symbols have the following descriptions:
The file, drive, or folder is not selected. If the item is a drive or folder, the folders and files in it are also not selected.
The individual file or folder is selected.
The individual folder or drive is selected. All items within the folder or drive are also selected.
The individual folder or drive is not selected, but one or more items within the folder or drive are selected.
In the Create New Scan - Scan Options dialog box, you can modify any of the following options:
Change which file extensions the client scans. The default setting is to scan all files.
Change first and second actions to take when viruses and security risks are found.
Construct a message to display when a virus or security risk is found. You can also configure whether or not you want to be notified before remediation actions occur.
Change additional scan features, such as displaying the scan results dialog box.
Change which computer components the client scans. The options that are available depend on what you selected in step 3.
In the Create New Scan - When To Scan dialog box, click At specified times, and then click Next.
In the Create New Scan - Schedule dialog box, under Scan Schedule, specify the frequency and when to scan, and then click Next.
Under Scan Duration, you can specify a length of time during which the scan must complete. You can also randomize the scan start time.
Under Missed Scheduled Scans, you can specify an interval during which a scan can be retried.
In the Create New Scan - Scan Name dialog box, type a name and description for the scan.
For example, call the scan: Friday morning
