Is Antivirus Software Necessary?

You may ask yourself why you need antivirus software when your computer comes with, or makes readily available, free antivirus software found in Windows Defender and Microsoft Security Essentials. Windows Defender has been available since the Windows Vista days as an antispyware program, designed to monitor and detect programs that try to gather information about you without your knowledge. With the release of Windows 8, Windows Defender was upgraded to offer additional antivirus protection features. Windows 10 comes with Windows Defender built in to the operating system itself. Microsoft Security Essentials offers antivirus protection against viruses, spyware, Trojans and rootkits, and it is available on Windows XP, Vista and 7 but not on Windows 8.

With these protections in place, why would you ever need to download a third-party antivirus program? The answer is performance.

Although Windows Defender and Microsoft Security Essentials offer built-in support and Microsoft continues to improve upon these systems, they don’t generate high scores in the tests conducted by AV-Test, the respected independent antivirus software test lab. This is expected to a point, as these programs were designed as a baseline of protection for users who don’t plan on purchasing commercial antivirus protection. However, AV-Test regularly publishes its test results comparing both Windows Defender and Microsoft Security Essentials to the top third-party antivirus programs. The third-party systems score higher every single time.

So, is antivirus software necessary when Windows already has built-in protection against virus? Although baseline virus protection can give you some sense of security, you want the top-performing antivirus programs to make sure you are always protected. AV-Test tests two separate categories of malware or virus interception: the detection of widespread and prevalent viruses and the detection of zero-day, or brand-new, malware attacks. In both categories of tests, Windows Defender and Microsoft Security Essentials performed poorer than the industry standard, regardless of which Windows operating system was used during the tests. This means that third-party antivirus programs are more capable of protecting your computer, and you, against malicious virus attacks.
