- While there are some types of security software that offer blanket protection from a variety of potential threats, most security software is designed to guard against a specific security risk. Antivirus software, firewall software, encryption software and spyware removal software are just a few of the specialized programs available. Antivirus and spyware removal software are the versions most often used to protect personal computers, since the risks posed to said computers by viruses and spyware is so high.
- Any computer program that can download and run without your knowledge or permission is considered a virus. Such programs are often self-replicating and can easily slow down or damage the computers supporting them. Antivirus software is a type of security software designed to remove viruses from a computer's hard drive. Because new viruses are constantly being developed, most antivirus software can be updated to recognize the most recent viruses using downloadable program profiles.
- Unlike antivirus software, which is used to protect computers from hostile programs, firewall software is used to protect private networks from unauthorized user access. Hardware systems can also be used to create firewalls, as well as a combination of hardware and software programs. When a firewall is in place, messages and other data must pass through it to enter or exit the network. This allows any unauthorized or potentially damaging data to be detected and its movement halted automatically.
- Spyware is a term used for any computer program that uses your Internet connection to collect personal information without your permission or knowledge. Such programs are often used by advertisers to monitor your Internet activity and help them determine what ads are most likely to appeal to you. The purpose of spyware removal software is to safeguard your Internet privacy by scanning for active spyware programs and removing any that are detected.
