optimization does not affect the performance of your
computer.
Optimization rearranges file fragments into adjacent
or contiguous clusters in the hard disk. It improves the
computer performance by reading the files into the
memory faster. Optimization also maximizes the usable
free space on a disk by grouping most frequently used
files and infrequently used files. In addition, it
consolidates free space to avoid fragmenting newly
added files.
You can use the IdleTimeOptimizer option to optimize
the boot volume during the idle time. To access the
Idle Time Optimizer option, go to the Norton Internet
Security main window, and then click Settings >
General > Norton Tasks > Idle Time Optimizer.
