Antivirus software is a critical tool for both individuals and businesses. Mobile or stationary electronic devices which do not have up-to-date antivirus software can become infected within minutes of connecting to the internet. The threat of bombardment is constant, and viruses change on a daily basis. Companies that provide antivirus software have to continuously update their detection tools to protect against the approximately 60,000 new pieces of malicious software that are created on a daily basis.

Companies that provide antivirus software, including McAfee, Norton, Symantec, AVG, and Trend Micro, among others, all perform similar basic functions for users. These include:

  • Scanning files or directories to detect malware and malicious patterns.
  • Allowing the user to schedule scans or run them automatically.
  • Allowing the user to initiate the scanning of a particular file or document and any external storage devices.
  • Removing malware detected on the computer—the user may be notified when an infection is detected and asked how to proceed. Some programs complete this step automatically.
  • Showing you the health status of your computer or device.
