Why Trust Techopedia

How to choose antivirus software is a question plenty of people are asking today – protecting your devices from malware, spyware, and other digital threats is critical, after all.

In this guide to how to choose antivirus software, we’ll dig into what makes a good antivirus product and the factors you should look into before making a purchase.

How to Choose Antivirus Software That’s Right For You

The best antivirus software will scan your system for threats and protect you from being exposed to viruses online. Choosing the right antivirus software can be a challenge, though, given the sheer number of options available on the market.

Here are seven factors you shouldn’t miss when picking the best antivirus software for your device.

Detection Rates

This is the number of threats detected by an antivirus compared to the total number of threats on a device.

For maximum security, look for antivirus solutions that clock very high detection rates under testing. Modern antiviruses often boast rates ranging from 97% to 99% or more – the higher, the better.

Equally, pay attention to the rate of false positives that antiviruses flag – when the software identifies something as a virus when it’s not a threat. The lower the false positive rate, the better. An antivirus with a high detection rate and a high false positive rate isn’t ideal.

There are several third-party platforms, like AV-Test and AV-Comparatives, which undertake forensic independent testing to rate antivirus solutions on their detection rates and performance, and we use their scores as benchmarks.

Real-Time Protection

Modern antivirus solutions should be able to scan your devices in real time and prevent threats from accessing your system.

Make sure the provider you pick can scan downloads in real time and remove threats immediately, ideally even responding to zero-day attacks.

Robust web protection is also important to stop you from being targeted by malicious websites. After all, unsolicited downloads and sketchy websites are the top sources of modern viruses.

Ease of Use

A good antivirus should be easy to use. Make sure your chosen solution has a simple interface and several scan options.

You can ensure you’re happy with a product by taking advantage of the free trials offered by providers. Also, pay attention to the scan options provided, such as quick scans and folder scans, to make sure you can find everything you need.


Although protection against viruses is important, it should come at a reasonable cost. Look into the pricing plans for antivirus solutions before finalizing your pick.

Providers often offer significant introductory discounts but then have hefty renewal fees. Pay attention to the long-term costs of using a particular antivirus solution so you’re able to get the maximum possible value out of the deal.

Additional Features

Alongside their core functionality – scanning and removing viruses – many antivirus platforms offer additional features, including VPNs and password managers. These are also part of the cybersecurity toolkit and help to keep you safe from malicious actors.

A VPN masks your IP address so hackers and marketers can’t track you. Password managers, meanwhile, help you access and maintain strong, unique passwords for all your online accounts, minimizing your vulnerabilities.

Cybersecurity providers often bundle these tools with their antivirus solution. If you’re getting additional protection for only a marginal increase in price, you should definitely consider it as a bonus.

Most leading antiviruses include a firewall today, but our firewall vs antivirus guide covers the key differences between the two.

The Provider’s Reputation

Antivirus software has access to all your system files, so it’s important to ensure you only purchase products from reputable providers. After all, you don’t want to fall prey to data breaches or to inadvertently purchase a fake antivirus.

Reputable providers like TotalAV, Norton, TrendMicro, ESET, and Avast have been in business for years and have made a name for themselves in the cybersecurity space. If you want to go with a less well-known provider, read their security and privacy statements and ensure they have proper governance.

Free Plan and Money-Back Guarantees

It can be wise to opt for platforms that offer free plans and money-back guarantees.

Free plans come in handy for testing products before you put money down, while money-back guarantees underline the provider’s confidence in their software.

Can I Get Free Antivirus Software?

There are plenty of free antivirus solutions that can help you protect your devices without incurring any costs. For example, Microsoft provides a proprietary antivirus tool called Microsoft Defender Antivirus, which comes pre-installed with the operating system and offers real-time protection.

Here are some pros and cons of using free antivirus software.


  • 100% free – You get protection without spending a penny
  • Basic protection – Free solutions are good if you’re on a budget and want basic protection


  • Lack of advanced features – Free software is often basic and lacks advanced features
  • Lack of support – You’ll often have to rely on forums and community support
  • Security concerns – Free antiviruses don’t guarantee total security and some are even fake antivirus scams

A number of providers offer free antivirus products. Avast is among the best with a free-forever plan, while Malwarebytes has a free antivirus for Windows. TrendMicro, on the other hand, has a range of targeted tools, including software to fight ransomware, phishing and web threats, and already installed viruses.

What Mistakes Do People Make When Buying Antivirus Software?

Picking the right antivirus software comes with its own challenges, and it’s only natural that people make mistakes. Here are some mistakes you should avoid.

Ignoring renewal prices – Many buyers only look at the initial pricing when choosing an antivirus, but renewal prices are often higher. See our Malwarebytes vs Norton guide, which compares a product with a free plan to one with a higher renewal rate.

Not reading reviews – It’s always a good idea to read reviews before you buy an antivirus, such as the ones you’ll find in our antivirus guides, which cover pros and cons and the issues that users face.

System slowdowns – It’s important to have an antivirus, but they can have an impact on your system’s performance, so make sure your machine can handle the software and that your pick isn’t detrimental to normal use.

Regular updates – After purchasing an antivirus solution, it’s important to update it regularly. New malware and security threats are emerging every day, so it’s important to get the latest updates from your antivirus provider.
