Kaspersky Internet Security Vs Windows Defender
Heberto Calderon
Norton 360 Deluxe combines excellent malware protection with loads of extra features like backup software, a password manager, a VPN and more. It can get expensive but you get everything together in one subscription.
Bitdefender Antivirus Plus offers very good malware protection with lots of useful extra features like a password manager, Wi-Fi scanner, a hardened browser and more. It also has a light system impact during active scans for viruses.
McAfee has improved its malware protection over the years and it's a great choice if you want to protect lots of machines on a budget. It also includes a password manager as well as protection for multiple platforms.
All of Norton's antivirus products offer excellent malware protection, and the once-heavy system-performance load is much lighter. The number of extra features each program has varies, but the sweet spot in the lineup is Norton 360 Deluxe.
It includes a password manager that works on all major platforms, unlimited VPN service, dark-web personal-data monitoring, parental controls and up to 50 GB of online storage space. Two other offerings, Norton 360 Premium and Norton 360 Platinum, give you more online storage and expand the antivirus and VPN coverage to 10 and 20 devices, respectively.
If you want full-on identity protection, Norton offers three bundles with varying degrees of LifeLock service and even more online storage. Their subscription prices run well into the triple digits, but still cost less than if you were to buy the identity protection, password manager, cloud-backup storage and antivirus software separately.
Unlike some of the other best antivirus software makers, Norton doesn't offer a file shredder, file encryption or secure web browser with any of its products. Yet every other digital-protection service you could possibly ask for is included with at least some of its bundles.
Bitdefender Antivirus Plus is our top choice among entry-level antivirus products. It has very good, if not perfect, malware-detection scores. Its active scans don't add much to the background system impact, but that background load is a bit heavy.
The midrange Bitdefender Internet Security adds parental controls, webcam protection and a two-way firewall, while Bitdefender Total Security tops off the lineup with an anti-theft feature for laptops, a system optimizer and licenses for Bitdefender Antivirus for Mac and Bitdefender Mobile Security for Android.
Despite that, the entry-level McAfee AntiVirus Plus is a bargain: $60 per year buys software for up to 10 (in practice, unlimited) devices, whether they run Windows, macOS, iOS or Android, and the software comes with a file shredder and a two-way firewall.
To get parental controls or one of the best password managers in the business, you'll have to spring for McAfee Total Protection or its sibling McAfee LiveSafe, which comes pre-installed on many new PCs.
The multi-device licenses of those two security suites also come with an identity-protection service. But none of the McAfee products have a secure browser or webcam protection, which you often get with other premium antivirus programs.
At the top is McAfee Total Protection Ultimate, which adds unlimited VPN service with no strings attached. Hardcore PC gamers may consider McAfee Gamer Security, which for $60 per year offers low-overhead protection for a single rig.
The brand's entry-level program, Trend Micro Antivirus+ Security, has basic tools but does have a secure web browser. Parental controls, a system optimizer and a file shredder are bundled into the mid-range Trend Micro Internet Security.
However, none of Trend Micro's programs include a two-way firewall or webcam protection, standard with other brands' midrange offerings. Nor does the premium product have the cloud storage or backup software that some of the best antivirus brands add as extras to their flagship packages.
ESET is one of the biggest antivirus names in Europe, with a very small system-performance load and fast scans. Its malware-detection rate used to be kind of meh, but has improved markedly in recent lab tests.
The entry-level ESET NOD32 Antivirus is easy to use, but has few useful extra tools. ESET Internet Security adds webcam protection, parental controls and a browser-hardening extension, as well as ESET security-software licenses for Mac, Android and Linux devices.
Because it's spun off from Sophos' enterprise software for business clients, Sophos Home Premium lacks many of the bells and whistles other security suites offer, such as a password manager, identity theft protection service or VPN service.
What Sophos Home Premium does have is the essentials: ransomware rollbacks, webcam defenses and protection against keyloggers, malicious websites and boot-sector and fileless malware. It also has a web-filter system for parents and an online management console from which you can tweak most of the settings.
Free antivirus software used to offer subpar protection while being full of ads and suggestions to upgrade to a paid antivirus program instead. Now though, Kapsersky offers a free version with excellent malware protection. Likewise, Bitdefender Antivirus Free for Windows is another free antivirus worth checking out.
A merger between Avast and AVG created a combined malware-detection engine that is much better than the sum of its parts. Likewise, Microsoft Defender Antivirus is now one of the best free antivirus programs out there and it comes built-in with both Windows 10 and Windows 11.
Microsoft's built-in antivirus software is now a heavy hitter. While Windows Defender, aka Microsoft Defender Antivirus, doesn't quite beat Norton or Kaspersky in malware-protection lab tests, it comes out ahead of Avast, AVG and most other free antivirus products while operating almost entirely behind the scenes.
You won't be getting many extra features with Windows Defender itself, yet Windows 10 does have parental controls, a gaming mode and protections for its own Edge and Internet Explorer browsers. There's no built-in VPN, but you also won't be bothered by pop-ups trying to upsell you to paid antivirus software.
As for a password manager, there's a stealth one built into the Microsoft Authenticator app for Android and iOS that syncs with the Edge browser, as long as you're signed into your Microsoft account on all devices.
We still recommend going for Kaspersky Security Cloud Free, which has even less of a system impact, better malware protection and more useful extras, but there's absolutely nothing wrong with using Windows Defender as your primary antivirus solution as it's good enough to secure your new laptop.
Compared to premium paid antivirus programs that are big, heavy and loaded with extra bells and whistles, Bitdefender Antivirus Free Edition is like a '60's sports car, stripped to the essentials but still providing plenty of power.
Bitdefender Antivirus Free Edition offers nothing but the basics. There's no password manager, no gaming mode, no quick scans and no scan scheduling. You can manage the software from the program's System Tray icon, but you don't really need to interact with Bitdefender Antivirus Free Edition after its installation.
It's the best free antivirus software if you want a security solution that you can set up and then forget about. It's also perfect if you need to protect the computer of an elderly relative but don't have time to manage antivirus software from afar.
Avast Free Antivirus has the best assortment of extra goodies of any free antivirus program, including a hardened browser, a gaming mode, a Wi-Fi network scanner and a ransomware shield. (Unfortunately, the unlimited password manager has been discontinued.)
However, Avast Free Antivirus caused a pretty heavy system load in our testing and its scans took a long time. It also kept nagging us to upgrade to Avast's paid antivirus protection, and played bait-and-switch with features that looked like they were free but weren't.
Most significant of all, the malware protection in Avast Free Antivirus is a peg down from Kaspersky's or Bitdefender's, whose free programs also bothered us less about paid upgrades and had lighter system loads.
But AVG AntiVirus Free also has far fewer useful extra features than Avast Free Antivirus. While the latter is almost a free security suite with lots of bells and whistles, AVG AntiVirus Free is the quiet, neglected child that gets the hand-me-downs.
The good news is that AVG's wide range of customization options and its file shredder and system optimizer are still available, and its interface is open and easy to use. The bad news is that like Avast Free Antivirus, AVG AntiVirus Free constantly bugs you to upgrade to paid antivirus software.
What's the difference? Unlike antivirus software, Malwarebytes Free can't prevent a PC from being infected. But it does an excellent job of cleaning out malware that's already on your system, as well as removing (legal) adware and potentially unwanted programs that antivirus software often ignores.
Malwarebytes Free doesn't interfere with any antivirus software that's already installed, so it's perfectly safe to install it alongside one of our recommended brands. (Just don't upgrade to the paid Malwarebytes Premium, true antivirus software that does poorly in lab tests and which will conflict with other AV programs.)
Most vendors offer single-device licenses for Windows PCs. But multi-device, multi-platform licenses for five, 10 or more computers and mobile devices are available in midrange and premium antivirus packages, covering Windows, macOS, Android, iOS and sometimes even Linux. Some vendors offer plans that cover an unlimited number of devices.
Gone are the days when you could walk into a store and pay a one-time fee for an antivirus product that came in a box off a shelf. All the vendors now sell their software licenses as yearly (or multiyear) subscriptions. The upside is that you'll always get the latest software, which you can download and install straight from the internet.
