Best Antivirus Software for 2024

In addition to the four antivirus apps we recommend above, 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.

We're here to help you find the antivirus software that best fits your needs. These picks of the best antivirus programs are a combination of recommendations from independent third-party labs AV-Test, AV-Comparatives and SE Labs, as well as CNET's anecdotal hands-on testing. 

Note that antivirus software is only one piece of the cybersecurity puzzle. Cybercriminals are becoming more sophisticated, and the more steps you take to lock down your online security, the safer you'll be. A secure virtual private network can help protect your internet privacy, and a password manager can help protect your personal information. 

Test after test, Avast Antivirus for Windows performs 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. Avast was in the news for several months for its non-antivirus business, so we looked at the company, specifically reports at the end of 2019 that Avast allegedly collected user data with its browser plug-ins and antivirus software and then sold data it collected through its Jumpshot subsidiary in early 2020.

In response to the reports that his company gathered and sold the details of its customers' online activities, Avast CEO Ondrej Vlcek said in a statement that he understood that his company's actions raised questions of trust in his company. To address that, Avast terminated Jumpshot data collection in January 2020 and closed its operations because the data collection business wasn't in line with Avast's privacy priorities.

Those reports followed another in 2019 from Avast that its internal network was breached, possibly to insert malware into its CCleaner software, similar to an earlier CCleaner hack that occurred before Avast acquired the Windows utility.

Avast started saying the right things about taking its customers' privacy seriously, but it only came to that point after reacting to investigative reporting that revealed the Jumpshot practices. (The CCleaner revelations, while concerning, were self-disclosed, which is important to building user trust.) We hope Avast's more privacy-friendly policies mean that there will be no further Jumpshot-style activities and that it returns to glory as one of the best antivirus software options. In the meantime, we'd recommend using one of the many other solid choices in this realm (listed above).

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."

The Commerce Department recommends those who use Kaspersky software switch to replacement software from other security companies as soon as possible. To aid Kaspersky customers with the transition, Kaspersky will be allowed to provide antivirus updates to its software till Sept. 29, 2024, the department said.

Picking the best antivirus software for Windows means finding one that keeps your PC safe, doesn't take up a lot of system resources, is easy to use and stays out of the way till you need it. Here's what to look for.

Effectiveness: Antivirus software runs virus scans for known viruses and malware and can offer real-time protection. It watches 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.

Light on system resources: You don't want antivirus software that taxes your PC's resources. If after you install the program, websites open slowly, apps download or open sluggishly or file copies take longer than expected, you may want to try another service. The good news is that all our picks offer a free trial or money-back guarantee to let you try out the antivirus program, so if your system feels sluggish 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: The prices we list above are for 10 devices -- if the company offered that package -- but you can trim your cost with antivirus packages if you need to cover three or five devices. You may also find discounts on an app's Amazon page.

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 read their privacy statements to learn what the companies do with the information you share.

Protection for other platforms: Microsoft is by far the biggest target for viruses and malware. Android is second, with just under 1% of apps installed on Android devices with Google Play Protect in the potentially harmful app, or PHA, category.

The threat to MacOS and especially iOS is low, in part because of the tight control Apple has over its app stores. While the 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.
