You Don’t Need to Buy Antivirus Software

We aimed to create a comprehensive Wire cutter guide on the top antivirus apps. We spent months researching various software options, analyzing Independent testing labs, institutions, and consulting reports that have been reviewed with experts on safe computing. Ultimately, we discovered that most individuals do not need to purchase a traditional antivirus suite like McAfee, Norton, or Kaspersky, nor should they rely on free programs like Avira, Avast, or AVG. The best option for most people is to use nothing at all. Microsoft’s built-in tool, Windows Defender, is sufficient for most users’ needs.

We dedicated countless hours to researching and analyzing data from reputable sources such as AV-Test and AV-Comparatives and publications like Ars Technica and PCMag. We also studied various reports and releases from organizations such as Usenix and Google’s Project Zero to gain insight into the latest viruses, ransomware, spyware, and other malware that commonly target computer users today.

Throughout the years, we have engaged in conversations with security experts, IT professionals, and the information security team of The New York Times (the parent company of Wire cutter) to sift through the constant back and forth regarding antivirus software. The typical headlines of “antivirus is useless” or “antivirus is unnecessary” can be overwhelming and confusing. Still, with their input, we have provided clearer and more informed recommendations.

While we test all products in most categories, we rely on independent test labs for antivirus suite performance.

It is unwise to rely solely on one antivirus app to safeguard your system, data, and privacy since even the most trusted antivirus programs have shown vulnerabilities. No antivirus can detect every malicious software that enters your device, whether paid or free. In addition to antivirus protection, you must use secure passwords, enable two-factor authentication, encrypt your data, regularly back up your system, keep your software updated, and use privacy tools in your browser. It is advisable to only download software from official sources, such as Microsoft App Store and Apple Mac App Store. Be cautious when downloading email attachments.

We do not recommend using a traditional antivirus suite.

A security app cannot simply protect against known “viruses.” Malware comes in various encrypted forms, disguised as trustworthy programs, and can wreak havoc once opened. Antivirus companies try to outsmart these encryption services by constantly updating their detection systems. Still, they cannot keep up with the ever-evolving tactics of malware creators who are determined to break through.

Here’s a quick explanation of some important terms: “Malware” refers to any software that causes harm or unintended effects when it runs on your computer. On the other hand, “antivirus” is an older term that software makers still use, even though viruses, Trojan horses, and worms were the big threats in the 1990s and early 2000s. While technically all viruses are a type of malware, not all malware is a virus.

There are several reasons why you should not install a full antivirus suite from a well-known brand just to be safe.

• Vulnerabilities: The way antivirus apps provide protection can be problematic due to their need for high access privileges. This means that when the app is insecure or malfunctioning, it can become a liability as it has significant control over the system. Even major antivirus vendors like Symantec Norton and Kaspersky have experienced critical vulnerabilities.

• Performance: Antivirus software is known for its negative impact on computer performance. It can slow down the computer, interfere with other apps like Firefox and Chrome browsers, and cause distractions with frequent reminders and subscription or update offers. Additionally, it may install insecure browser extensions without clear permission from the user.

• Privacy: Regarding antivirus software, free options often come with privacy concerns. These apps may collect data about your computer usage and sell your private browsing information. Additionally, they may install browser extensions that compromise your security and add unwanted advertisements to your email signature. Investing in good, paid security software is important to avoid these issues.

Most people don’t need traditional antivirus software due to these reasons.

 

Windows Defender is mostly good enough.

If you’re using Windows 10, you don’t need to install an antivirus or anti-malware software because Windows Defender is already installed and enabled by default. In December 2019, Windows Defender received a recommendation from the AV-Test Institute’s independent testing and was rated almost perfect in performance.

Windows Defender is pre-installed on Windows 10 and created by the company that developed the operating system. As a result, it doesn’t try to sell you subscriptions or use certificate trickery to provide comprehensive protection for your system. It won’t install browser extensions or plug-ins for other apps without your permission. However, malware makers often target Windows Defender first, so it’s important to take extra precautions, such as using official app stores and avoiding downloading questionable free versions of paid software. Following these tips can protect you from the most harmful Defender-defeating malware.

In September 2019, Windows Defender was criticized by AV-Test for its inability to detect certain zero-day malware attacks. However, in December of the same year, Windows Defender regained its reputation by resolving real-world testing issues and successfully detecting 100% of the attacks. Windows Defender consistently performs as well as any paid third-party antivirus software in lab tests. In May 2017, when a significant vulnerability was identified in Windows Defender, Microsoft took swift action by releasing a patch on Monday evening following a Friday night disclosure.

 

No antivirus software can achieve perfect scores from every test lab every month. Still, Windows Defender typically performs as well as, if not better than, its competitors. Plus, it’s free and enabled by default.
