By default, virus and spyware scans to minimize the effect on your client computers' resources. You can change some scan settings to optimize the performance even more. Many of the tasks that are suggested here are useful in the environments that run Symantec Endpoint Protection in guest operating systems on virtual machines (VMs).
The settings that are available are different for Windows computers and Mac computers.

Task | Description | ||
|---|---|---|---|
Modify tuning and compressed files options for scheduled and on-demand scans | You can adjust the following options for scheduled and on-demand scans:
See Customizing administrator-defined scans for clients that run on Windows computers. | ||
Use resumable scans | For computers in your network that have large volumes, scheduled scans can be configured as resumable scans. A scan duration option provides a specified period to run a scan. If the scan does not complete by the end of the specified duration, it resumes when the next scheduled scan period occurs. The scan resumes at the place where it stopped until the entire volume is scanned. Typically you use the scan duration option on servers.
See Setting up scheduled scans that run on Windows computers. | ||
Adjust Auto-Protect settings | You can adjust some settings for Auto-Protect scans of the file system that might improve your client computers' performance. You can set the following options:
| ||
Allow all scans to skip trusted files | Virus and spyware scans include an option called Insight that skips trusted files. By default Insight is enabled. You can change the level of trust for the types of files that scans skip:
| ||
Randomize scheduled scans | In virtualized environments, where multiple virtual machines (VMs) are deployed, simultaneous scans create resource problems. For example, a single server might run 100 or more VMs. Simultaneous scans on those VMs drain resources on the server. You can randomize scans to limit the impact on your server. See Randomizing scans to improve computer performance in virtualized environments. | ||
Use Shared Insight Cache in virtualized environments | Shared Insight Cache eliminates the need to rescan the files that Symantec Endpoint Protection has determined are clean. You can used Shared Insight Cache for scheduled and manual scans on your clients computers. Shared Insight Cache is a separate application that you install on a server or in a virtual environment. See Configuring your clients to communicate with Shared Insight Cache |
Table: Adjusting scans to improve performance on Mac computers
Task | Description |
|---|---|
Adjust scan priority | Applies to scheduled scans on clients that run on Mac computers. Scan priority on Mac computers is equivalent to tuning or performance adjustment on Windows computers. High priority means that the scan runs as fast as possible, but other applications may run more slowly during the scan. Low priority means that other applications run as fast as possible, but the scan may run more slowly. Medium priority balances the speed at which applications and scans run. See Customizing administrator-defined scans for clients that run on Mac computers. |
Modify compressed files setting | Applies to Auto-Protect and on-demand scans. You can enable or disable the option, but you cannot specify the level of compressed files to scan. |
