Maintenance Tasks (Enhance
Performance and Ensure Security)
Performing Maintenance Tasks to Increase
Computer Speed and Ensure Security
Your computer may begin to run slower over time. Slower performance can be
caused by:
• Disorganized files
• Unnecessary software
• Unused network drives
• Too many programs that run automatically at startup
In addition, viruses can cause serious damage and dramatically slow your
computer's performance.
You can protect your computer, increase its operational life, and enhance its
performance, if you perform standard maintenance tasks, such as:
• Cleaning the computer and its components
• Disk defragmenting
• Scanning for virus and spyware
