The Virtual Memory sensor has detected a low amount of disk space available for virtual memory.
Virtual memory enables your computer to run more applications simultaneously than the installed physical memory (RAM) would otherwise allow. Potential virtual memory includes any free disk space plus any space in the swap file not currently used for temporary data storage. When virtual memory gets low, computer performance deteriorates, running applications may not work properly, and you may not be able to start any new applications.
Making more space available on the disk or moving the swap file to another local hard disk with more space will increase the potential virtual memory. Click System Settings, then click the Performance tab, and click Virtual Memory to move the swap file to a different local hard drive
The trigger level for this sensor's alarm determines what Norton System Doctor considers "low" space. To change the trigger level, click Change Alarm Settings.
