Why we picked Norton 360 Deluxe

An ideal antivirus suite packs in a little of everything needed for security without costing a ton—and that’s why our pick for the best antivirus software of 2024 is still Norton 360 Deluxe. Despite its slightly awkward interface, this software’s wide protection and affordable pricing is ideal for most users.

This plan has just about everything most PC users need, without extra bloat. For antivirus performance, Norton offers strong online protection, while having minimal impact on system resources if you don’t often download or copy large amounts of files. Additionally, you get malicious link and attachment screening, dark web and privacy monitoring, and webcam safeguards. Norton also tosses in 50GB of storage for cloud backups, access to Norton’s password manager and VPN, parental controls, and PC utilities that include the ability to monitor for outdated software. And those major extras—the password manager, VPN, and parental controls—have easy, simple interfaces, without feeling stripped to the bone.

Overall, Norton is an excellent option for those looking to consolidate their online security protections into a single software interface. It has a couple of quirks (namely a dual user interface that can mildly slow navigation), but its strengths far outshine its weaknesses, especially when it packs in so much value. You’ll pay $50 for the first year for 5 devices, and $120 per year thereafter.

Who should use Norton 360 Deluxe

Norton 360 Deluxe works for everyone—it consolidates all the biggest protections you need online into one package, including parental controls. If you have trouble keeping up with security experts’ recommendations (or haven’t yet gotten around to following all of them), this suite centralizes and simplifies it all.

Why we picked Avast One

Avast not only offers solid protection, but a simple, friendly interface. Combine that together with useful extra features and multi-device coverage, and you have a winning combo in Avast One.

In addition to top-ranked antivirus protection, it offers safeguards against remote webcam takeovers, malicious websites, and trackers. The Avast One plan also includes dark web monitoring, a VPN with up to 5GB of bandwidth per week, and protections for saved passwords to a browser. You get utilities to help you keep your PC’s drivers up to date, clean up your PC, and optimize your apps, too.

These features may sound standard, and to be fair, many of them can be found in rival software. But Avast makes staying on top of security dead simple, whether you’re a novice or a security veteran. Its default settings require little input to keep your PC protected, and if you want to dig in further or tinker, you still have that option, too.

So what keeps Avast out of the top spot, when its software outperforms Norton’s? The amount of features for its price. Norton’s performance isn’t perfect, but it’s about as good for online protection, which is where it counts. And the two software plans cost about the same—Avast One is $51 for 5 devices (or $70 for up to 30 devices) during the first year. The cost rises to $110 and $150, respectively, per year afterward. In the end, the more well-rounded subscription wins out.

Who should use Avast One

You’re someone who has a password manager already set up, don’t need parental controls, and prioritize the highest marks in threat detection tests. Avast One lacks the first two features, and takes top marks for catching both online and offline risks.

Why we picked AVG Internet Security

AVG is best known for its excellent free antivirus software, but there’s good reason to upgrade. AVG Internet Security not only offers more comprehensive protection, but also easy management of those tools. That can be valuable if you find keeping up with online threats too overwhelming or time consuming.

The Internet Security plan builds upon the free version’s top-ranked protection against malware and web, email, and network threats. It also guards the passwords saved to your browsers; webcam takeovers; unknown access to files with sensitive data; malicious redirects for websites you’re trying to visit (aka DNS hijacking); and Windows Remote Desktop attacks. Dark web monitoring is included as well. And the app has minimal impact on system resources when monitoring your system in the background, though full scans can hit budget or older systems harder.

Despite its small annoyances (like ads for additional paid features), AVG Internet Security is reliable antivirus software with a user friendly interface—and at just $60 during the first year for 10 devices, it’s affordable, too. In fact, it’s solid enough to earn a recommendation despite how strong the free version is on its own.

Who should use AVG Internet Security

You need deeper control and more expansive protection from your antivirus software, but you don’t want to pay extra for features you don’t want. AVG Internet Security expands just enough on the company’s free antivirus to make it worthwhile, even though it lacks elements like parental controls, VPN, and a password manager.

Why we picked Avira Prime

Avira Prime is one of the best choices for those seeking more help with managing their PC, thanks to its simple, clear interface and feature lineup. In addition to to solid antivirus protection, it offers a password manager, unlimited VPN, and a boatload of PC utilities that (among other things) can keep apps up to date, securely delete files, and back up data.

The one major feature missing from Avira Prime is a set of parental controls. You can’t use it to filter web content or monitor device usage. It also can hit older and budget PCs hard when full scans are running, if you’ve added or changed large amounts of files. But typically, it only minimally affects system performance when left to run in the background, so most people won’t notice Avira running.

For those who want the comprehensive simplicity that this security suite offers, you’ll pay $60 for the first year, and then $105 for every year after. That first-year cost is slightly higher than our overall top pick, but if you prefer more newbie-friendly software, it’s worth the extra ten bucks.

Who should use Avira Prime

Avira Prime will likely feel best to users who want a simple antivirus suite, broad online protections, and robust PC utilities—and also want to use those latter tools for more confident management of their computer. Not every utility is a winner, but the overall set can help you identify and understand the more technical aspects of Windows and system upkeep. Parents will need to look elsewhere for controls that let them monitor and limit their kids’ PC use, however.

Why we picked McAfee Total Protection

McAfee has been around a long time—and the company continues to hunt down current threats to PCs, with solid results. These days, dangers extend beyond just malware to identity and privacy issues, and McAfee Total Protection addresses these just as much as it does ransomware and phishing sites.

That ID protection makes it stand out against competitors, especially if you pay to scale up the service. The plan we tested included dark web scanning for multiple pieces of personal information (email address, phone number, social security number, passport, driver’s license, date of birth, tax ID, credit card, usernames, and more). The app also offers to help change your password for online accounts, when applicable. VPN access is included as well.

Mid-tier and budget machines can see impact on system resources when running McAfee scans. When we ran a full scan during a variety of common tasks (web browsing, document editing, etc), we noticed some dips in performance. You can mitigate this effect by timing scans for off hours, however.

Currently, McAfee Total Protection is available through third-party sellers (McAfee has turned its attention to its slightly newer McAfee+ plans on its website). We like this version still because of how deeply affordable it is—for example, a license on PCWorld’s own software site is just $19 per year, which covers up to ten devices for one year.

Who should use McAfee Total Protection

Your personal information can be used against you online—and with data breaches so painfully common these days, it can be a relief to have help in tracking who has your info. For anyone who doesn’t have as much time to handle that work themselves, or even keep track of a separate service, McAfee can serve as a central spot for managing all your online security concerns.

Why we picked Panda Dome Complete

All deluxe antivirus suites offer extra tools as part of their package, but Panda Dome Complete particularly stands out. It also has one of the most striking interfaces we’ve seen. Similar to Microsoft’s Bing homepage, Panda Dome features a beautiful background photo, with the interface elements placed on top of it.

A whole raft of utilities come with this suite, including a virtual keyboard, advanced virus removal, an update manager for your Windows apps, a disk defragmenter, hard drive cleaner, and startup apps manager. You also get Wi-Fi protection (which lets you see what devices are connected to your network), a password manager, parental controls, and a VPN that offers 150 megabytes of bandwidth per day.

In addition to offering reliable antivirus protection, Panda had the most minimal impact on system performance during our benchmarks. So minor, in fact, that in the real-world it worked out to no difference.

As one of the most feature-rich offerings, Panda Dome Complete also one of the most expensive, too. You can purchase a subscription for $64.50 during the first year ($86 per year afterward), but that’s covers just one device. Fortunately, it only costs a little more to upgrade to a three device plan ($72 for the first year, $96 per year afterward) or five device plan ($79 for the first year, $105 per year afterward).

Who should use Panda Dome Complete

Panda Dome Complete puts a ton of features right at your fingertips—an ideal interface for those who want to dive into everything straight away. If you hate buried or oversimplified menus, you’ll feel right at home with this software.

Why we picked Windows Security

Windows’ built-in security suite is an excellent free antivirus option—as we discovered in our roundup of the best free antivirus—even if its protection isn’t quite as strong as third-party rivals when your PC is offline. It bundles together Defender, which monitors for viruses and malware; Firewall, which blocks malicious incoming traffic and suspicious outgoing traffic; ransomware protections (including controlled access to folders, as well as data recovery via OneDrive integration); app restrictions; and even basic parental controls.

The most important of these protections are automatically enabled in Windows—you don’t have to lift a finger to get real-time antivirus scanning or network protection. You will have to manually switch on some features, though, including ransomware folder controls and file recovery.

You can find more features in other antivirus suites, like online privacy tools, a VPN, and encrypted cloud backups. But this free protection comes preinstalled on Windows machines and does a good job of keeping you protected from most threats.

Who should use Windows Security

You’re looking for lightweight, unobtrusive antivirus protection—and don’t mind configuring it, nor managing separate security tools to make sure you’re properly protected online. To get the most out of it, you must tinker with Windows Security’s settings. (You can learn more in our video on How to use Windows Security.) You also have to figure out your own online privacy tools, VPN, password manager, and encrypted cloud backup.

Why we picked Intego X9

As the headline reveals, the focus of this roundup is the best antivirus for Windows PCs, but many PC enthusiasts are the de facto IT for friends and family. If you want to help an associate or loved one achieve strong antivirus protection for an Apple machine, our colleagues at Macworld recommend Intego’s Mac Internet Security X9.

In the suite are two utilities. The better known one is VirusBarrier, which spots and eliminates malware threats, and gets strong ratings for its protective abilities. It comes paired with NetBarrier, a two-way firewall that watches for suspicious traffic going to or from your Mac. For the price of this suite, NetBarrier’s inclusion isn’t common, but definitely welcome.

As part of its protection, VirusBarrier X9 scans for threats on your Mac’s internal storage drive (including any downloaded email and compressed archives), as well as connected disks and iOS devices. The app quarantines suspicious files, which you can then mark as trusted, leave in quarantine, or try to have repaired.

Overall, Intego’s Mac Internet Security X9 offers good compatibility with macOS while looking like a real Mac program, too. It costs just $25 (or £20.00) for the first year using this special Macworld link. If you need additional tools, like a backup utility, speed optimizer for your Mac, or parental controls, you can upgrade to the Mac Premium Bundle X9 for $40 for the first year (£23.99).

Who should use Intego X9

Intego VirusBarrier not only offers good compatibility with macOS, but it also looks like a real Mac program, too—making it an ideal match for anyone looking for an effective app that blends in seamlessly.

The short answer is maybe, but probably not. Antivirus software scans files and programs to ensure there is no malware or other harmful threat present. The longer the time frame between each scan, the more files the program will need to check. These intensive scans may have some noticeable effect on your computer speed. It’s therefore recommended that you schedule your scans to run more frequently and/or at night so as to not impact your computer usage.

While antivirus software can affect the speed of your computer, it is most likely not the only factor—or even the most prominent. Other factors such as unnecessary startup and background programs, insufficient RAM, or even undiagnosed malware can have more drastic effects on your computer speed than a simple antivirus scan.

It depends on what antivirus features are most important to you. Do you just need a program that will scan, detect, and remove malware? Then go with a free version. But if you are looking for more advanced features such as the ability to block webcam hacking, run suspicious apps in a sandbox environment, and permanently delete sensitive files, then you should seriously consider upgrading to a paid premium antivirus service. 

Overall, premium antivirus software is better suited to more complete coverage against threats—especially for inexperienced users. Children and seniors are particularly vulnerable to modern threats and therefore paid antivirus apps, which allow for multiple-device protection, may be a better option for families.

In a perfect world, your antivirus software will halt and clean the infected files for you. However, this largely depends on which antivirus program you are using.

In general, the antivirus will send a warning to you and try to quarantine the infected file in order to keep it from spreading. Once isolated, the software will give you the option to try to remove the infection or delete the file altogether.

A full scan performs a comprehensive and thorough check of your whole system. It usually checks your system memory, startup programs, system backup, email databases, hard drives, and any removable storage drives.

A quick scan only checks a few areas including startup programs, system memory, and boot sectors. It may not detect all malware, but it can usually give you an idea if your computer has a virus.

As to when you should do either, we recommend a full scan once per week, during computer usage downtime (such as late at night). A quick scan can be done anytime you like, but it’s usually only necessary if you notice suspicious activity on your PC.

Absolutely! Keeping your antivirus software up-to-date is crucial in helping you to avoid the most recent threats.

That being said, most antivirus software today—whether free or paid—will default to automatic updates. This way you don’t need to worry about manually updating your software. It may still be worth checking to confirm that your antivirus is running the most up-to-date version from time to time.
