Internet Security

Connecting to the internet, whether via e-mail or the web, exposes computer users to a whole host of threats, including viruses that can alter, corrupt and delete files, freeze your computer or otherwise interfere with computer operation.

Internet security software is a computer program which, like antivirus software, detects and takes action against viruses and worms. However, it has other security features that are important if you surf the Net:

  • It blocks unwanted content such as spam or pop-up windows
  • It includes family protection features (parental controls)
  • It protects your digital identity
  • It prevents damage to your computer while you surf the web
Internet security software should work quietly in the background while you are online or using your computer.

Internet security relies on specific resources and standards for protecting data that gets sent through the Internet. This includes various kinds of encryption such as Pretty Good Privacy (PGP). Other aspects of a secure Web setup includes firewalls, which block unwanted traffic, and anti-malware, anti-spyware and anti-virus programs that work from specific networks or devices to monitor Internet traffic for dangerous attachments.
