Notes 6. Avoid and Remove Spyware: Spyware is a type of malicious program that runs invisibly

on your computer that can detect and delete spyware. This software can be part of antivirus
software or purchased separately.

program. Programs can contain viruses that will infect a computer.

cannot be attacked when it is off or not connected to the Internet. Rebooting is a good idea
for maintenance reasons as well.
