Originally sold as Antivirus Expert or AVX, Bitdefender has protected Windows and MacOS computers since 1990. Bitdefender's service expanded to cover iOS and Android in the 2010s, ensuring protection for all of your devices.
Why we like it
Bitdefender consistently earns top marks for its antivirus protection and usability from respected independent antivirus testing labs like the AV-Test lab.
The Bitdefender Ultimate Security plan includes antivirus software for up to five devices and a slew of other privacy and security tools, including a VPN, password manager, parental controls, email protection (for local email tools like Outlook), an autopilot tool to help you understand how secure your computer is, plus webcam protection. US users with a valid Social Security number can also get identity theft protection, including up to $2 million in identity theft insurance.
Additionally, you’ll get two performance-enhancing tools: a One-click Optimizer that aims to help you find ways to speed up your device and a Battery Mode tool for configuring how much power individual device functions use to improve your laptop's battery life. However, it’s worth noting that these tools -- and the firewall protection offered by Bitdefender -- aren’t available for MacOS.
Who it's best for
BitDefender Ultimate Security is your best choice if you want a suite of tools to protect all of your digital activities, including email and other online activities.

Pricing
Bitdefender Ultimate Security starts at $90 for the first year and renews at $160 per year, with protection for up to five devices. Along with its Total Security offering, Bitdefender Ultimate Security includes a password manager and VPN. You can upgrade to Bitdefender Ultimate Security Plus for $120 for the first year ($180 on renewal), which adds identity theft protection and insurance of up to $1 million -- a feature well worth the extra money if you've got significant assets to protect. If you just want antivirus software, you can get coverage for one device for $30 in the first year ($60 per year on renewal) -- or even grab the free version. But since most folks own multiple devices, we recommend Ultimate Security for comprehensive coverage.

The company's products include Antivirus Plus, Norton Secure VPN, Norton 360 for Gamers, Norton 360 with LifeLock Select and more. Some of these tools were originally limited to Windows, but they’re now compatible with MacOS, as well.
In addition to malware and virus protection for your computer and mobile device, this security suite provides 100GB of cloud backups, safe-browsing tools, a VPN, a password manager, parental controls and LifeLock identity theft protection and fraud alert.

Pricing
A 10-device subscription for Norton 360 with LifeLock Select is normally $190 per year, but you can get your first year for $80.

Avira's antivirus software entered active development in 1986. Its creators spent the next 20 years perfecting it before finally launching it in 2006. Since then, Avira has been installed millions of devices around the world.
Why we like it
Avira Free Antivirus uses the same high-scoring antivirus engine as the paid version of Avira, a popular antivirus software serving over 500 million users. Avira Free offers real-time protection against viruses and other malware, plus a scanning tool to find and remove any malware that sneaks past its protection. You can run scans manually or schedule them to run automatically on a daily or weekly basis.
Unlike most free antivirus tools, Avira Free Antivirus offers multilayered protection, including protection from ransomware and phishing. This protection is included with Avira Free Antivirus for Windows, MacOS, iOS and Android.
Windows users get access to a software updater, a tool that finds and updates out-of-date software to improve system security.

Founded in 2004, Malwarebytes started as a tool for removing malware from computers. It has since grown into a full antivirus service with real-time protection and other benefits.
Why we like it
Malwarebytes protects your PC from viruses or malware attacks, scoring reasonably well in recent independent testing for guarding against malware threats -- but it’s primarily known for its ability to find and remove any malware that’s already found its way onto your computer.
Who it's best for
Malwarebytes is your best bet if you think malware has already infiltrated your computer and you want to get rid of it.
Pricing
You can get protection and disinfection for one device for $45 a year. You can add more devices for $5 per device per year.
Factors to consider when choosing antivirus software
Picking the best antivirus software means finding one that keeps your PC or mobile device safe, doesn't consume a lot of system resources, is easy to use and stays out of the way until you need it. Here's what to look for.
Effectiveness
Antivirus software runs scans for known malware and can offer real-time protection. It can also watch for shady websites and suspicious links to keep you out of trouble. It can also offer ransomware protection and monitor unexpected behavior that may be a sign of new and not-yet-identified viruses and malware. You want antivirus software that can successfully identify these unknown online threats without flagging too many false positives.
You can determine an antivirus software’s effectiveness by looking at its detection rate in tests performed by labs like the AV-Test lab. None of this software is perfect -- malware is evolving all the time -- but you should look for software with an 80 to 90% detection rate.
Light on system resources
You don't want antivirus software that taxes your PC's resources, like RAM and CPU power. If after you install the program, websites open slowly, apps download sluggishly, software opens leisurely or copying files takes longer than expected, you may want to try another service. The good news is that all of our picks offer a free trial or money-back guarantee to let you try out the antivirus program before you buy, so if your system feels bogged-down after installation, you may want to keep looking.
Cost and discounts
Don't just pay the sticker price for antivirus protection. Before you buy, check for discounts on a company's website. Another way to save: You can trim your cost with smaller antivirus packages if you need to cover three or five devices rather than, say, 10. You may also find discounts on an app's Amazon page or at outlets like Best Buy.
During the purchase process, pay close attention to renewal costs. Most antivirus tools charge annual fees and only offer discounts for the first year (though you may be able to get a discount by paying for two years up front). These promotional prices might lead to you paying more -- sometimes as much as double the original amount -- for following years.
Bundled services
Antivirus software may come bundled with other security tools like a password manager and a VPN. Buying a security suite with all of these tools lets you manage everything from one account, saving you the hassle of managing multiple accounts -- and it can save you money, too.
However, the VPNs in these security bundles aren’t always the best tools available. You may want to purchase separate subscriptions or choose a VPN with antivirus if privacy is a major concern.
Privacy
To be effective, antivirus software needs to monitor what's going on with your PC, check in with company servers about unusual behavior and provide sound banking protection. The companies say they anonymize this technical data as much as possible to protect your privacy. If you want to know more, the security companies on our list post privacy policies on their websites, so you can read their privacy statements to learn what the companies do with the information you share.
Protection for other platforms
Many modern computers come with built-in antivirus software -- Microsoft Defender for Windows 10 and 11, X-Protect for Mac -- and this is sufficient for some users. However, you may want to invest in one of the antivirus tools listed here for added protection, especially if you store sensitive files on your computer and/or rely on it for your income.
Microsoft is by far the biggest target for viruses and malware. Android is second, with 0.15% of apps installed on Android devices (with Google Play Protect) in the potentially harmful app, or PHA, category as of January 2024.
The threat to MacOS and especially iOS is low, in part because of the tight control Apple has over its app stores. While Mac does come under attack via side-loaded apps, it's rare, and if you download apps only from the Mac and iOS app stores and keep your guard up when clicking links and downloading files, you should be OK without an antivirus app on Apple devices. Thankfully, you can stay safe when downloading apps by sticking with official app stores, reading reviews and consulting privacy policies.
Issues with Avast
In test after test, Avast Antivirus for Windows performed well for malware detection, with options ranging from Avast free antivirus software to Avast Premium Security. We've included its antivirus in our list of recommended security app options before.
However, early in 2024, the Federal Trade Commission fined Avast $16.5 million to settle charges that claimed the company had sold customer browsing information to more than 100 third parties from 2014 to 2020. Avast allegedly collected the data through browser extensions and antivirus software and sold the data through its Jumpshot subsidiary, the FTC claims. As part of the settlement, Avast is prohibited from selling or licensing any web browsing data for advertising purposes.
In response to the initial reports in 2020, then-Avast CEO Ondřej Vlček said in a statement that he understood that his company's actions raised questions of trust. To address that, Avast terminated Jumpshot data collection in January 2020 and closed its operations.
We hope the FTC actions mean that there will be no further Jumpshot-style activities and that Avast returns to glory as one of the best antivirus software options. Until then, we recommend using one of the many other solid choices in this realm (listed above).
Issues with Kaspersky
Let's talk about Kaspersky Lab, specifically about the 2024 federal ban, announced on June 20, prohibiting Kaspersky from directly or indirectly selling antivirus or cybersecurity software or services in the US or to US citizens. This sweeping ban follows a more limited one in 2017 that prohibited Kaspersky software and services on federal government computers because of alleged ties between Kaspersky and the Russian government.
Based in Moscow, Kaspersky Lab has for years produced some of the highest-rated antivirus software for business antivirus needs and home customers. Its software consistently earned top scores and awards for virus and malware detection and endpoint protection from independent testing labs.
“Russia has shown time and again they have the capability and intent to exploit Russian companies, like Kaspersky Lab, to collect and weaponize sensitive US information, and we will continue to use every tool at our disposal to safeguard US national security and the American people," Secretary of Commerce Gina Raimondo said in the official announcement of the ban.
In a statement, Kaspersky said it "does not engage in activities which threaten US national security and, in fact, has made significant contributions with its reporting and protection from a variety of threat actors that targeted US interests and allies."
How we test antivirus software
Our research process starts with looking at each antivirus company's website to evaluate its features, additional security tools (like VPNs) and pricing to determine its overall value. We also consider the operating systems and number of devices each antivirus tool can protect, prioritizing tools that can protect all of your computers and mobile devices.
If our initial research shows that a company provides a broad range of high-value security tools for multiple devices and operating systems, we review that company's test results from AV-Test. AV-Test is an independent third-party lab that tests antivirus tools for their performance, protection and usability. Antivirus tools that consistently receive a ranking of at least five out of six in all three categories are added to the list.
Other antivirus software to consider
In addition to the antivirus apps we recommend, a handful of other anti-malware tools are worth considering among the best antivirus protection if you find them at a better price or just prefer to use one over our picks above.
Trend Micro Maximum Security
Maybe this antivirus provider isn't as well known to consumers because of its focus on enterprise security, but Trend Micro antivirus security quietly brings its business expertise to the home with its Trend Micro Maximum Security tools. Trend Micro's software earns high marks from AV-Test -- consistently scoring well for detecting zero-day attacks and widespread viruses and malware. Trend Micro also does a good job of not taxing system resources. Trend Micro's antivirus for home users starts at $20 for the first year ($40 per year after).
ESET NOD32 Antivirus
If you're looking for something easy to set up and use, ESET NOD32 antivirus may meet your needs. It earns high scores for usability and offers solid virus protection. A five-device option is available for as little as $60 for a year on the base package, with a five-device one-year plan on its mid-range Essential tier running $70. ESET NOD32 has a 30-day free trial so you can try before you buy.
