Don’t Skip Out on Antivirus Software in 2023

Protect your PC from nasty viruses this flu season. Here’s what’s best for malware protection and more.

You might think you’re smart enough to avoid viruses, but even the smartest of tech aficionados can get fooled — yes, even us. That’s why it’s so important to invest in an antivirus software that can efficiently protect your system. These programs can help protect not only your devices, but your information as well, which hackers, scammers and other internet bandits would love to get their hands on. These rascals are getting smarter every day, developing new techniques and methods all the time. Fortunately, there are tons of great antivirus softwares available in 2023, so you’ve got plenty of options to keep your computer safe. We’ve put some of the most popular softwares out there to the test to bring you the best antivirus software options out there.

Windows devices make up three out of every four laptop or desktop operating systems, according to the latest data from Statcounter. Windows-targeted malware has a larger base of devices to infect, giving it more potential in the eyes of cybercriminals.

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 own hands-on testing. We regularly research and test software to determine which product leads the pack, and we update this list periodically based on those tests.

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 will help you create and keep track of more secure login credentials. These tools are all essential in protecting your personal information.

Our recommendations

Whether you’re looking for free antivirus protection or are willing to pay for a program that offers more security features, we have you covered. Here’s where to start when looking for the best antivirus software for your specific needs.

Note: The pricing structure for antivirus services can be complicated, since providers often offer low introductory prices to entice you to sign up for their services. After the first billing period — typically a year or two, depending on the plan you purchase — the amount you pay for the service may increase substantially. The regular rate for the services may be double the introductory rate or sometimes more. Be sure to check the terms of the subscription plan prior to making your purchase so you don’t get an unwelcome surprise when your subscription renews.

Also worth considering

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.

What about Avast?

Test after test, Avast Antivirus for Windows performs well for malware detection with options ranging from Avast free antivirus software to Avast Premium Security. And we’ve included its antivirus in our list of recommended security app options before. But 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 prior to Avast’s acquiring 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).

What about Kaspersky?

Because the company has been in the news the past few years, let’s talk about Kaspersky Lab — specifically about the federal ban that blocks US government agencies from using Kaspersky Antivirusproducts.

Based in Moscow, Kaspersky Lab has for years produced some of the best antivirus software for business antivirus needs and home customers. But in 2017 the US government prohibited Kaspersky security cloud software on federal government computers because of alleged ties between Kaspersky and the Russian government.

Notably, the ban does not apply to its consumer products such as Kaspersky Total Security and Kaspersky Anti-Virus. But as with China-based Huawei, the question remains: If the federal government doesn’t think the products are safe enough for its own devices, should consumers avoid them as well?

In a statement sent to CNET, the company said, «Kaspersky Lab has no ties to any government, and the company has never, nor will ever, engage in cyber offensive activities. Kaspersky Lab maintains that no public evidence of any wrongdoing has been presented by the US government, and that the US government’s actions against Kaspersky Lab were unconstitutional.»

In Kaspersky’s favor, it continues to earn top scores and awards for virus and malware detection and endpoint protection from independent testing labs. And it’s reasonably priced.

In the end, even though no one has ever publicly produced a «smoking gun» linking the company to Russian intrigue, we think any of the options listed above is a safer bet. And if you are a US government employee or work with the federal government, you’ll want to steer clear of Kaspersky internet security products — and perhaps use one of the antivirus software products mentioned here instead.

Antivirus basics: What to look for

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, of course, and can offer real-time protection. And 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, 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 should provide sound banking protection. The companies say they anonymize this technical data as much as possible to protect your privacy. But 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. But Android is second, with just under 1% of apps installed on Android devices with Google Play Protect in the potentiallyharmful 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 download files, you should be OK without an antivirus app on Apple devices.

Antivirus FAQs

Can antivirus protect against phishing?

To a degree, yes. Some antivirus programs can do things like warn you or block you from visiting a suspected phishing site. Others may also automatically block suspicious emails that appear to come from a malicious sender or contain phrasing common in phishing emails. However, you cannot count on an antivirus program to be a failsafe solution for phishing protection. You still need to be vigilant and know what to look out for on your own when it comes to phishing, because an antivirus program won’t be able to catch everything.

Will antivirus slow down my computer?

Any program running on your computer will require a certain amount of processing power to work, which can affect your computer’s overall performance. If an antivirus program is just running in the background, it shouldn’t really have any effect on your computer’s performance. However, when actively running a scan of your system, an antivirus can noticeably slow down your computer. If this is the case, try to schedule antivirus scans at night, or at a time when you’re not using your computer.

Everything Announced at Apple Event 2025: iPhone Air, iPhone 17, AirPods Pro 3 and New Apple Watches

Apple’s annual September reveal of its latest mobile devices featured the brand new iPhone Air, AirPods Pro 3 with heart-rate sensing, the iPhone 17 lineup and new Apple Watches.

Each September, Apple’s product release playbook dials up the unveiling of the company’s newest line of iPhones, along with a variety of complementary gadgets. On Tuesday, the company took the wraps off the iPhone 17 in all its variations, most notably the new skinny iPhone Air, along with new Apple Watches — Series 11 and Ultra 3 — and an upgrade to its 2-year-old AirPods Pro 2 earbuds.

Along with the hardware, Apple is rolling out the new versions of the devices’ respective operating systems, iOS 26 and WatchOS 26, both of which have been in public beta all summer. (The final version of iOS 26 will be available on Monday, Sept. 15.) The new Liquid Glass interface design may even seem routine to you by now.

Many of the new devices’ capabilities come from new features in their operating systems, and throughout Apple stressed health and fitness as one of the primary drivers. It deemphasized how many of the features’ analysis capabilities — notably most of the new heart-rate sensing and Live Translation in the AirPods Pro 3 — really rely on the iPhone for their heavy lifting.

Given Apple’s struggles with its AI efforts, especially given how much it stressed Apple Intelligence at previous events, the company came as close to downplaying it as it could: There was only the occasional mention of features being driven by AI and the increased neural power in the new A19 Pro processor. And despite no discussion of smart home tech, there was a brief hint in the iPhone Air announcement.

iPhone 17 boasts a better screen

The update to Apple’s most mainstream model comes in pastel colors. Notably, the base iPhone 17 now has a ProMotion (120Hz VRR) display, which was formerly only on the Pro models. The screen is larger (6.3 inches) and brighter (up to 3,000 nits) with an improved scratch- and glare-resistant coating. ProMotion has been a much-wanted upgrade; I think there’s probably some dancing going on right now. Inside, it incorporates the A19 chip with a five-core GPU and adds fast charging.

The new front camera has an 18-megapixel square sensor for more flexibility in framing, alongside a larger field of view to enable Center Stage and stabilization. It still has two cameras, though the main camera is bumped to 48 megapixels via Dual Fusion or 24 megapixels as standard.

It starts at $799 in the US — the 16E remains in the line at $599 — and all the iPhones are available for preorder now. It’s £799 in the UK and AU$1,399 in Australia.

The iPhone Air is thin but powerful

Thin seems to be in for phones this year — at least for manufacturers, since buyers don’t seem to be quite as interested and iPhone buyers even less so. Did anyone ask for a super thin iPhone? But in the continuing absence of a foldable iPhone model, what’s a company to do? Behold the iPhone Air, at 5.6mm thick.

It has a polished titanium frame and Ceramic Shield on both sides, which makes some people just want to touch it. According to the company, it’s almost entirely battery on the inside, with Apple claiming all-day battery life.

It’s got high-end specs, too: a 6.5-inch ProMotion XDR display and the A19 Pro processor found in the Pro models. The processor incorporates neural accelerators into each GPU core (six of them), bigger caches and more, giving it quite a bit of computing power.

A new N1 chip and C2 modem improve connectivity (Wi-Fi 7, Bluetooth 6) and power conservation. The device has 48-megapixel Fusion and 12-megapixel wide-angle cameras, the Center Stage front camera, and a way to combine front and back cameras live.

It requires all-new accessories, including a MagSafe pack (80 hours) and a thin, translucent case. It starts at $999 (£999, AU$1,799).

iPhone 17 Pro and Pro Max deliver a love letter to videographers

The flagship iPhone Pro models tend to differ only by screen size (now 6.3 and 6.9 inches), and their unique features are made possible by their higher-powered processors, more flexible camera arrays and other component differences over the lower-end models.

Like the Air, the iPhone 17 Pro uses an A19 Pro processor with updated cooling and thermal management — a vapor chamber — and has a Ceramic Shield back and front. Apple promises 39 hours of video playback.

The cameras are usually the highlight of the Pro, and that remains true: It has an 18-megapixel front Center Stage camera and a triple-camera Fusion Telephoto system, with three 48-megapixel cameras, including a 4x-8x telephoto for a maximum of 200mm equivalent. The phones can capture ProRes Raw and Genlock (to synchronize cameras for video), which should tickle the fancy of pro videographers.

The Pros now come in orange, which isn’t everyone’s favorite, and there’s a new 2TB storage option. They start at $1,099 (£1,099, AU$1,999).

Apple Watch Series 11, Watch SE and Watch Ultra 3 get redesigns

The Apple Watch Series 10 is our Editors’ Choice for smartwatches. The next-generation Watch Series 11 shrinks the thickness, with a more scratch-resistant front glass. It adds 5G support and better power management for up to 12 hours of battery life. A new Flow watch face takes advantage of Liquid Glass visuals. It adds blood pressure tracking (based on blood flow) to find indications of high blood pressure and sleep score from WatchOS 26. Prices start at $399 (£369, AU$679).

There are new bands in new colors, too.

It’s been three years since the last iteration of the Watch SE. Now, we get the Watch SE 3, with the new S10 chip with 5G wireless. It still delivers 18-hour battery life and an always-on display. There’s wrist temperature sensing for ovulation tracking, it gets sleep apnea tracking, sleep score and more. Prices start at $249 (£219, AU$399), and preorders start now.

Apple’s top-of-the-line smartwatch, the Ultra 3, is updated over the Watch Ultra 2 with a wide-angle OLED (smaller bezels mean more display area). Apple has given it emergency-related satellite connectivity, which required a new antenna and receiver. It also comes with increased battery life. Prices start at $799 (£749, AU$1,399).

AirPods Pro 3 upgrade includes live translation

The AirPods Pro 2 version released in 2023 offered only incremental hardware upgrades over the 2022 models (hence the lack of a name change). The AirPods Pro 3 are smaller, with an updated design that introduces foam-ish eartips for better noise isolation and upgraded active noise cancellation, live translation with adaptive ANC for better focus on the speaker, five sizes of ear tips and IP57 water resistance. Fitness enhancements include heart-rate and calorie tracking, among other updates, which come from iOS. Battery life increases to eight hours with ANC and 10 hours with transparency.

The live translation can be somewhat awkward, though, or as CNET’s Macy Meyer puts it, it’s fluent in convenience, not culture. The price hasn’t changed; they still start at $249 (£219, AU$429).

Notable new accessories for the iPhones

The iPhone Air debuts with new accessories. If you want to keep it thin and still have some level of protection, Apple is offering a $39 polycarbonate bumper that wraps around the edges. Aside from drop protection, I know I’d need it simply to keep the slight phone from slipping out of my hands. There is also a traditional $49 clear MagSafe Case along with an opaque Beats-branded polycarbonate case for $45. If for some reason you want to turn your ultrathin phone into a thicker one with longer battery life, you can pick up the $99 MagSafe battery.

The redesign of the camera section of the iPhone 17 Pro and Pro Max means it needs a new case design, and in addition to all the newly designed versions of the usual cases Apple introduced a $59 MagSafe case made of a new TechWoven material — colored yarns of recycled polyester woven into a textured material and coated with polyurethane, or PTU. Presumably, it will fare better than the FineWoven cases Apple released with the iPhone 15.

You can also get a novel (for Apple) $59 Beats Kickstand Case, which looks like the standard polycarb case. The kickstand, though, isn’t a kickstand; it’s a handstrap with a small bit on the end that you can use for standing the case on its side. The kickstand case also comes in a version for the iPhone 17.

For many of the iPhone cases Apple launched yesterday, the company introduced magnetic attachment points. That makes them compatible with its new $59 Cross-Body Strap. On one hand, I’m not sure I want to trust my $1,200 phone to some magnets or my propensity to walk into walls and doorways. On the other, it’s probably safer than my back pocket.

NASA Found Signs of Ancient Alien Life on Mars. Here’s How Excited You Should Be

NASA is finally releasing details on its discovery of Mars biosignatures and exactly what that means for alien life.

NASA released a significant update from the Perseverance Mars rover on Wednesday, focusing on a particularly juicy tidbit for those watching from home: A small rock sample called Sapphire Canyon showed signs of potential biosignatures, or ancient alien life that may have once grown on Mars.

That’s possible because of the unique location where Perseverance located the sample in July 2024. It came from a rock named Cheyava Falls. This particular rock is in Jezero Crater, home to an ancient dry riverbed. In other words, water once flowed abundantly in this spot, one of the most essential requirements for life as we know it.

A representative for NASA did not immediately respond to a request for comment.

While exploring, Perseverance’s cameras picked up colorful, leopard-like spots that eventually led to the Sapphire Canyon discovery.

«This finding is the direct result of NASA’s effort to strategically plan, develop, and execute a mission able to deliver exactly this type of science — the identification of a potential biosignature on Mars,» said Nicky Fox, associate administrator, Science Mission Directorate at NASA headquarters in Washington.

Life on Mars?

So, does this finally confirm that life once existed on Mars? It’s a very good start, and the most significant lead NASA has found so far.

The data collected by Perseverance using its onboard instruments (X-ray lithochemistry and NASA’s SHERLOC scanner) was peer-reviewed and appears promising, but it doesn’t absolutely confirm life. More tests and input are needed for that, and the samples could have been generated from a natural chemical process without the presence of life. But scientists are excited about these signs and eager to learn more.

What kind of Mars life are we talking about? It’s not the sort that comes in peace, or goes much of anywhere. The possible biosignatures indicate small, microbial life. Sapphire Canyon showed signs of vivianite and greigite. Vivianite, in particular, is found on Earth’s peat bogs and swamps, while greigite is a byproduct some earth microbes leave behind. Think of this finding like a potential algae or swamp scum.

NASA is working on analyzing the data, running more tests and sharing the results with other scientists around the world to see what more they can learn. There’s a lot to rule out, from accidental sample contamination to the likelihood of nonorganic origins. That’s tough to do from millions of miles away, but NASA is on the case.
