All in all, Intego offers excellent free software. You can combine it with some of the best Mac password managers for maximum results.

However, you need to remember that the free version of Intego antivirus does come with certain limitations. For instance, its free plan doesn’t cover real-time protection. Hence, your Mac device might be vulnerable to freshly created viruses.

Because of that, it’s worth checking the Intego Personal plan. It covers daily scans against all known viruses, malware, and ransomware. The price for an annual subscription is only $39.99, which is relatively little considering this antivirus hits 99.2% detection rates on AV-Tests against Trojans and worms.

Norton is one of the best spyware removal tools and has been around since 1990. It stands out with an impeccable 100% malware detection and removal success rate.

First of all, it’s important to stress that Norton doesn’t offer a traditional free virus protection tool. Instead, the company has decided to make the free trial and money-back guarantee its main competitive advantages.

Are Free Antivirus Software Solutions Enough?

Free antivirus software solutions can provide enough functionality to cover the most basic user needs. Free antivirus products will generally scan your device for malware and detect and delete harmful software on your device.

Best Free Antivirus Computer Scan

ESET NOD32 Antivirus computer scan optionsThis may be sufficient for an average user with limited needs – for example, if you want a basic level of protection while browsing the internet. However, some free security products only include performance optimization tools or data breach monitors and not the core scanning functionality.

Other free plans require you to engage with advertising or will persistently try to upsell you. If you want robust, multi-layered security, including virus scans, a firewall, and features to combat ransomware and phishing, you’ll get a much better package with even the cheapest paid plan.

Given this, if you run a startup or small business or simply need robust security for your own use then it will be very challenging to keep your network safe with a free plan.

You can also see our guide to the best free VPNs, which explores why cheap alternatives may be better than free solutions.

What Features Can I Expect From a Free Antivirus Program?

You can’t expect the same level of protection from free and paid versions of an antivirus. Getting a premium version, though, will generally protect you from known and unknown threats with 99% accuracy or higher.

The most common security features you can expect to find in a free antivirus are:

  • Anti-malware scanner For protection from known malware and PUAs on your system.
  • Anti-phishing protection Scans your email inbox to block phishing emails that may contain malicious content.
  • Low battery impact – Some free antiviruses are equipped with a low battery impact feature to reduce the device’s battery consumption.
  • Download scanning – Protect devices from online threats in real-time while downloading files.
  • Performance scan – The best free antivirus will provide you with tips on how to remove unnecessary files to optimize your system’s performance.
  • Home network scan – Looks for potential risks and protects devices that connect to your home WiFi.

Ideally, the best free antivirus protection will offer all the features mentioned above, with scanning being the most fundamental.

How to Choose the Best Free Antivirus for PC or Mobile

Here are the essential factors to consider when choosing the best free antivirus solution for personal or business needs.

Type of ProtectionPerformance ImpactCompatibilityPrice of the Paid PlansCustomer Service

Type of Protection

Before even considering getting free internet security software, you should think about the type of protection you really need. The most common free antivirus uses are:

  • Virus scan and prevention
  • Malware, ransomware, spyware and worms removal
  • Blocks spam and ads through browser extensions
  • Firewall protection against phishing attacks
  • Protection against zero-day malware
  • Home network security
  • Removable device scan
  • Identity theft prevention

For example, if you’re using a home network, getting the best free antivirus software can protect you from hacker attacks. Hackers can easily access your personal, business, or bank information through cracks in your home network protection.

Getting the best WiFi router isn’t enough. The best antivirus software free tools are a great addition to your home WiFi security system. It adds an extra layer of protection and prevents hackers from gaining control over your home devices. As a result, you should look for a free antivirus with a WiFi scan feature.

On the other hand, if you intensively browse the web, it would be a good idea to look for antivirus programs that offer automatic and on-demand free virus scans and protection against phishing sites.

The benefits of having free antivirus protection are many. It’s up to you to choose the one that suits your needs the best.

Performance Impact

Each antivirus solution comes with different features. Because of that, the antivirus software impact on your machine will be different as well.

For instance, an antivirus solution offering real-time protection will consume more energy from your device than the one with webcam protection only. Having a cost-free antivirus installed may result in:

  • Slowing down your device while launching websites
  • Lowering the download speed and installation of frequently used apps
  • Sluggish app launch
  • Slower file copying

You’ll find many variations here. For example, Intego has a 0% influence on your computer speed while downloading. However, it may slow down the installation of some popular apps by 82%.

Best Free Antivirus Reports
Antivirus reports

On the other hand, AVG will slow down your download by 1%. But, the app installation will be only 12% slower.

Naturally, your antivirus’s impact on your device will also depend on the machine’s configuration, age, operating system you use, and other factors.


Make sure to pick an antivirus that works well with your device and its operating system. Some free antiviruses may cover multiple platforms and are compatible with different devices. However, some antivirus solutions focus more on one platform or device type.

Many users rate TotalAV and Avast as contenders for the best free anti-virus for Windows and Android.

On the other hand, Avast is a popular solution for iOS devices, while Intego keeps Macintosh computers safe against online threats.

Price of Paid Plans

Any free antivirus comparison should consider the cost of upgrading. Make sure to check the selected antivirus pricing before you download the software.

Pick an antivirus that offers multiple pricing plans. This way, you’ll be able to keep enhancing the level of protection as your security needs increase.

Customer Service

Not all antivirus users are tech-savvy. Some find antivirus complex and annoying with all those security pop-ups and notifications. Sometimes, an action demands immediate attention, but you’re not exactly sure what to do. Should you remove the virus, leave it, or send it to quarantine?

Because of this, you should look for a free antivirus that offers the best customer service. That way, you’ll have support every step of the way, from the free antivirus download to the manual virus scan setting.

Free vs. Paid Antivirus – Pros and Cons of Using Free Antivirus Protection

You should choose a free antivirus if you only need basic protection. A free version typically scans the network, looking for online threats. It’ll alert you if your system has been compromised and will generally attempt to isolate and remove the threat.

Some free versions of an antivirus come with a browser extension. This is great for those who want security when browsing the web or when making online purchases. Some free antiviruses feature advertisements, which can be annoying but are a necessary evil as they make such software available for free.

On the other hand, if you need advanced help against hackers or want to obtain multi-level security, you should look for the best paid antivirus software plan. Antiviruses with paid subscription plans offer important features like real-time protection and protection from zero-day malware.

Finally, paid plans typically offer more customer service options. Some of them also come with the best VPN apps attached as well as password managers and parental control options.

You shouldn’t make any compromises when picking the best antivirus for your needs, and there are many affordable options for paid plans. Here are some of the pros and cons of free antivirus apps:


  • Free of charge
  • Some free solutions have great detection rates
  • Free picks often have solid antivirus and firewall features
  • Free antiviruses are generally easy to install and simple to get set up
  • Many products can be upgraded if you want additional features


  • May spam you with ads or share your data with third parties
  • Generally lack extras like password managers, VPNs, or data breach management
  • Free solutions lack ransomware, phishing, and fraud protection
  • Generally can’t provide protection for additional devices
  • Generally won’t include any customer service
  • Not suitable for protecting business networks

Are Built-In Virus Protection Services Enough?

Modern devices, including PCs (Windows 10 and 11), Macs, iPhones, and Android smartphones, have some built-in security protection. But are built-in antiviruses good enough to handle online threats?

In general terms, they do provide a reasonable level of basic protection. For example, the Microsoft Defender Antivirus, built for Windows 10 and 11 devices, recorded 100% detection results when faced with common malware in independent testing. The free Windows antivirus also issued an extremely small number of false reports and had generally minimal system impact.

Best Free Antivirus Scan
Antivirus scan progress

Of course, the Microsoft Defender Antivirus will only protect a single device and it can’t help you with securing Android phones, iPhones, or Macs. It also doesn’t offer additional security features like ransomware protection, password managers, VPNs, or download monitoring – and you need to use Edge for Microsoft to provide browser security.

The bottom line is that while built-in antiviruses may be broadly sufficient to cover basic needs, they don’t provide multi-layered protection. If you want to successfully defend yourself from hackers, identity thieves, and malware with 100% certainty, having the best tools available is smart to ensure you stay safe.

Best Free Antivirus Solutions for Different Device Types 

Antivirus operators provide varying levels of support for different devices, so the best free antimalware software for you will depend on exactly what device you’re using. Here’s a free antivirus comparison by device:


Free Antivirus for Windows

Windows is the most widely supported platform for free antivirus solutions by some margin.

It includes the Microsoft Defender Antivirus, formerly known as Windows Defender, and there are great forever-free antivirus products from Avast, Bitdefender, and AVG, as well as free trials from Norton and McAfee and money-back guarantees from all good providers.

Free Antivirus for Mac

The macOS operating system has a range of built-in security tools, but Macs aren’t immune to viruses by any stretch. Avast and AVG both offer free antiviruses for the platform, and you can enjoy trials and money-back guarantees for a range of antivirus products, as with Windows.

Free Antivirus for Android

Android devices also have built-in security features – but Avast, AVG, and Malwarebytes offer additional free security features. In addition, many products offer free antivirus trials and money-back guarantees so you can manage your security across devices with a single account.

Free Antivirus for iOS

The iPhone includes various security features and limits the access granted to third-party software. Nevertheless, there are several great cybersecurity products you can get for free for the platform, as well as free trials you can use to roadtest other free antivirus services.

Free Antivirus for Chromebook

Relatively few antivirus products are compatible with ChromeOS today, but you can use Malwarebytes and take advantage of other offers from providers, which can work in addition to Chromebook’s security systems.

Free Antivirus for Linux

While there are solutions for Linux network, endpoint, and server security, very few antivirus vendors provide consumer products for Linux today.

That said, there are open-source projects like ClamAV, which provide free security tools for Linux distros such as Debian and Ubuntu. Check out our guide to the best Linux antivirus software for more information.

How We Tested the Best Free Antivirus Software

It’s important to us that we thoroughly test all the products we feature in our guides, as well as researching vendors and their plans to provide a fully rounded view of their offerings. Here are some of the key criteria we used to rate the best free AV software:

  • Malware detection rates – Core antivirus functionality and the ability to detect and remove malware and viruses was a primary factor in our assessment.
  • System impact – Excellent performance is a high price to pay if it slows your system to a crawl, so we also looked at the system impact that each product had, as measured under independent testing.
  • Free status – We’ve included top free antiviruses with free plans, free features, free trials, or money-back guarantees. The more they had to offer at the lowest price possible, the higher we rated them.
  • Upgrade options – In addition to free options, we’ve considered what you get if you do decide to upgrade to the cheapest paid plan. We haven’t looked favorably on underpowered starter plans or excessive subscription costs for lower-tier options.
  • Customer feedback – It’s important to us to always incorporate feedback from real users so we can get the benefit of their experience using the product over the long term. We try to weigh up customer ratings and explore the downsides that users highlight.
