The CPU Usage sensor has detected that the Central Processing Unit (CPU) usage is high. This can indicate an inefficient use of computer resources or too many applications running simultaneously, and can degrade system performance.
Close any non-essential applications.
If this problem occurs often, your system is probably underpowered for the work you normally do. Consider upgrading your system to a higher-performance CPU.
The trigger level for this sensor's alarm determines what Norton System Doctor considers "high" CPU usage. To change the trigger level, click Change Alarm Settings.
