For many people, antivirus software is a thing of the past – a relic from the dial-up era where Norton and McAfee controlled 90% of the market. Furthermore, the incredible rise of virus-resistant Mac computers and devices in the ‘00s and ‘10s dictated a further drop in antivirus software adoption and usage.

Ironically, despite the average person’s disinterest in antivirus software, the cost of viral attacks is greater than it’s ever been. As of 2021, the cost of cyberattacks has reached over $5 billion – a number that is only projected to climb as our world becomes more digitized by the day.

With the impacts of viral attacks only growing in significance and frequency, having a robust antivirus is critical – for both your business and your own personal protection. Here’s some of the antivirus systems that are most trusted by industry professionals.

In addition, these recommendations are aimed at Microsoft users – the operating system of choice for 80% of businesses.

The Best Antivirus Services in 2023

1. Bitdefender Antivirus Plus

  • Overview: Bitdefender Antivirus Plus is a highly respected, extremely robust antivirus service. The big positive to Bitdefender is its fully 360° nature. It’s a comprehensive security suite designed to offer holistic, bulletproof protection against various cyber threats.
  • Features:
    • Ransomware Protection: Provides a dedicated defense mechanism against ransomware attacks – a type of viral attack that can be extremely difficult to detect.
    • Hardened Browser: Bitdefender has its own “hardened browser” that ensures safe online financial transactions, protecting against phishing and malicious websites. It basically makes sure you’re not getting faked out by duplicitous websites.
    • VPN Protection: A VPN is a must in 2023, and Bitdefender has it. A VPN protects your location data by “scrambling” your location – giving false information to would-be online ne’er-do-wells.
    • Ad Tracker Blocker: Nobody wants to be tracked. Ad tracking blockers prevent advertisers from tracking your online activities, enhancing privacy.
    • Security Patch Detector: Identifies and alerts users about missing security patches in their software, ensuring up-to-date protection.

  • Price: Varies, but typically around $30/year for one device.

2. McAfee AntiVirus Total Protection

  • Overview: One of the original antivirus pioneers, McAfee is still going strong as a comprehensive antivirus platform that prides itself on broad protection across devices.

  • Cons: Some features are limited to specific platforms, and can be resource-intensive.
  • Price: Varies, often around $60/year for multiple devices.

  • Features:
    • Malware Expertise: People love Malwarebytes for its incredible ability to find specific, unique, and new malware that other programs would struggle to find or define.
    • Behavior-based Detection: Instead of just relying on virus definitions, it monitors software behavior to detect malicious activities, ensuring protection against zero-day threats.
    • Ransomware Activity Detection: Like its behavior-based approach to viruses, Malware actively monitors for patterns consistent with ransomware activities. Once it’s identified patterns that appear as malware, it immediately takes preventive actions before the ransomware can encrypt your data.
  • Pros: Fast performance, real-time protection, effective against zero-day threats.
  • Cons: Limited features in the free version, might flag some legitimate programs.
  • Price: $38/year for one device, $100/year for five devices.

So What’s The Right Antivirus For Me?

If you’re a small business or a sole proprietor, you’re probably fine with a simple antivirus like Malwarebytes or Bitdefender. Even their free versions offer some robust security features – but don’t forget the massive risk you’re taking in leaving your system open.

If you’re a larger business (+10 employees), you definitely need an enterprise-level antivirus. In many cases, you may already have one in the form of something like Microsoft Defender.
At any rate, you’re going to have to do the same thing you do with every business decision – weigh the pros and cons of each and apply them to your unique situation. The main things to pay attention to when picking an antivirus are:

  • The cost of the product
  • The security needs your organization has
  • The compatibility of the antivirus with your existing systems
  • The usability of the antivirus software for the end user

Consider these things, but always always keep the end user in mind – as most cyberattacks are perpetrated via a human vector.
