If you want a computer to be perfectly secure, you could fill it with concrete and dump it in the ocean. This would protect any information on the computer from inappropriate use. Unfortunately, the computer would be completely unusable, so you probably don't want to do that! Since you want to both use your computer and keep it safe, you should practice good computer security. Computer security allows you to use the computer while keeping it safe from threats.
Computer security can be defined as controls that are put in place to provide confidentiality, integrity, and availability of all components of computer systems. These components include data, software, hardware, and firmware.
Security software is a general phrase used to describe any software that provides security for a computer or network. There are many types of security software including antivirus software, encryption software, firewall software and spyware removal software. Additionally, many operating systems also come preloaded with security software and tools.
The two most common types of security software used for personal computer security are antivirus software (virus protection software) and antispyware software (spyware removal software).
