Best antivirus 2001

That's too bad, because Kaspersky Security Cloud Free is the best free antivirus product we've ever tested. We've never seen such a combination of excellent protection and extra features in a free antivirus program. It's got a bright, comprehensible interface, a lot of customization potential and Kaspersky's unbeatable malware protection. The program also lets you schedule scans, and its performance impact was so small that it actually sped up our test machine a bit.

Kaspersky's useful extra features include a file shredder, an on-screen keyboard and an email scanner. The password manager and VPN service are fairly limited, however, unless you pay.

Bitdefender has officially discontinued Antivirus Free Edition, and it will be supported only until June 30, We still love it and you can still get it , but proceed at your own risk. 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.

Yet Bitdefender Antivirus Free Edition has the excellent Bitdefender malware-detection engine, which sits just below Kaspersky and Norton in the lab-test rankings. 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. Read our full Bitdefender Antivirus Free Edition review. 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.

Read our full Windows Defender review. 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 recently added ransomware shield. Unfortunately, the unlimited password manager has been discontinued.

The program is also very customizable, letting you tweak its appearance and functions to suit your style. It even offers limited access to Avast's VPN service. 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. Read our full Avast Free Antivirus review. AVG shares a decent, if unspectacular, malware-detection engine with its corporate sibling Avast while having a much lighter system-performance impact.

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. Worst of all, given its middling malware detection and dearth of extra features, there's no convincing reason to choose AVG AntiVirus Free over the built-in and overall better Microsoft Defender.

Malwarebytes Free, formerly called Malwarebytes Anti-Malware, is not antivirus software. Instead, it's a very useful malware-removal tool. 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. We recommend Malwarebytes Free as a complement to any of the best antivirus programs, free or paid.

If you have young children at home, then consider midrange antivirus products, most of which include parental controls. Do you want an all-encompassing security solution? Or are you a techie who understands and the risks of using the internet? Then a low-priced basic program might be all you need. MORE: How to buy antivirus software.

Once you've got your priorities figured out, then determine how many machines you'll need to protect. 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. Many antivirus products are sold online for much less than their list prices. But each brand offers basic, midrange and premium configurations of features and pricing, with every step up adding more features. Think of autos at a dealership. You can get a base-model car that will get you from place to place just fine.

For a few grand more, you can buy a car with satellite radio, but no heated side-view mirrors, alloy wheels or in-car Wi-Fi hotspot. Or you can spend a lot more to get a loaded car with all the fixin's. Antivirus makers also hope you'll spring for extra options, whether you need them or not. The one thing you can't trade up to is a bigger engine: All the Windows antivirus products in a given brand's lineup will use the same malware-detection engine and provide the same level of essential protection.

The software will have essential malware protection and maybe a password manager or a two-way firewall. If you want more then NortonLifeLock offers a range of higher-level suites.

Norton Standard adds some nifty extra bits of functionality, including an integrated full VPN service, more backup storage 10GB and dark web monitoring for some countries, including the US and UK. There are also strong mobile apps for Android and iOS. While Premium ramps that up again to 75GB backup and 10 devices. Editor's note: Unlike the other providers in this list, Kaspersky is yet to release the version of its antivirus. What follows is the description of its plan, and will be updated once we have tested the updates.

Its core antivirus capabilities are very strong, with Kaspersky ranking at or near the top in all the most recent reports from the big independent test labs. Kaspersky also benefits from some nifty self-protection routines. The good news is that when it comes to extras, the bigger suites bundle more interesting functionality.

Kaspersky Internet Security introduces an intelligent firewall which hardly ever bothers you with any queries , plus a secure browser, and it offers coverage for Macs, along with Android and iOS mobile devices. Kaspersky Total Security brings in more on top of all that, including smart parental controls, a fully-fledged password manager, and automated local or Dropbox backups.

Another strong suit is the fact that this antivirus is currently top dog when it comes to blocking phishing sites according to AV-Comparatives , and it provides great web browsing protection including Pay Guard as a secure environment for the likes of online banking.

Weak points? However, you do of course get more functionality with the higher-level security suites from Trend Micro. The next tier product, Trend Micro Internet Security, throws in some interesting extras including parental controls and social media protection tools. Whereas most updates on this list are fairly superficial, Avast ripped everything up and started again for its latest release - introducing Avast One.

Avast One takes the firm's trusted free antivirus now known as Avast One Essential and builds on it with extra features. Whether you choose to go free or upgrade, the software is really in favor with the independent testing labs at the moment, ranking towards the top of the pile in real-world malware tests and anti-phishing tasks. You also benefit from a simple firewall, data breach scanning to warn you if your online accounts are breached, and apps for Windows, Mac, Android and iOS.

So why bother paying for Avast One? You'd have to really want one of those specific add-ons to want to part with your cash, otherwise we'd suggest going for a more fully featured internet security suite or just sticking with the free Essential download. We saw a lot more thought pieces coming out in suggesting that the time was at an end to pay for your antivirus software. And while we generally disagree with that notion, Microsoft Defender is probably the best argument in its favor.

That's because if you're a Windows user, there's a perfectly capable virus protection already sitting within your operating system. Microsoft Defender is a solid product that gives capable mid-range protection - mostly without users ever even knowing it's there. Defender has a dashboard, its own scan options and so on, but you'll never even see them unless you go looking.

In the testing from independent lab AV-Comparatives, Defender ranked pretty much slap bang in the middle of the 17 tested providers. That means it's better at protecting your PC than even some of paid-for software out there.

Outside of pure virus protection, it features lots of bonus features such as multi-layered anti-ransomware, firewall, webcam and privacy protection, web filtering, parental controls and backup. So what's stopping you from forgetting the rest and simply getting Defender up and running? Well, those features mentioned above are all pretty basic and aren't up the standard of those offered by most of the security suites above. And it probably goes without saying that Defender is only available on Windows PCs - forget protecting your Mac or smartphone - and some features only play nice if you use Edge as your browser.

In truth, Avira is probably best known for its Avira Free antivirus option which is among the best out there - see further down this page , but its premium packages should not be sniffed at — especially when you consider the incredible price you can now pay for its Antivirus Pro package.

The interface is smart and the various features — including the free but limited to 1GB monthly VPN — are now better integrated within the UI overall. The caveat here is that the ratings of the antivirus engine from independent test labs are only middling at best — but the app does provide a decent enough level of protection. Upgrading to the Internet Security or Prime plan adds further features like a full password manager, and the Pro version of Software Updater which provides automatic updates for your apps , plus Prime gives you the unlimited usage version of the VPN and mobile app support.

A real bargain. McAfee takes an interesting approach with its security range, as all the offerings are variants of its core Total Protection product, with the main difference being more devices are supported at higher tiers. McAfee Total Protection Single Device is the entry-level antivirus product, and as the name suggests, it covers one device.

There are also a ton of features on offer, particularly for a baseline product, and even if not all of them are of the highest quality, you get a lot for your money. That includes an intelligent firewall, an integrated TunnelBear -powered VPN with unlimited data, a quality spam filter, secure file vault, and some PC speed-up options. The main stumbling block here is that the antivirus engine itself is not the best out there — although some results from independent test labs come out better than others — but this has to be something of a concern.

Further up the Webroot range, SecureAnywhere Internet Security Plus expands coverage from Windows and Mac PCs to mobile devices, also providing a password manager courtesy of LastPass and covering up to five devices rather than three. And at the top of the tree is Internet Security Complete which introduces an automatic backup tool with 25GB of secure cloud storage and additional online privacy features.

SecureAnywhere AntiVirus gives you everything you need, really, although Internet Security Plus is our top pick for the most rounded package. Sophos Home Premium covers up to an impressive 10 devices Windows and Mac computers. Sophos provides capable virus protection, and worked well in passing our own anti-ransomware tests. For the antivirus software on offer — and given the 10 device ceiling — Sophos Home Premium could work out as a great value proposition for those who want to protect multiple computers.

Just note that Sophos no longer offers a long-term free version to new users. You'll see on the website you can download it for free, but that's just a trial version rather than an all-singing all-dancing free antivirus package. We've tested all of the biggest names in internet security, we've found that the very best antivirus software in is Bitdefender. We also considered features such as multiple device protections and free version offerings.

A virtual private network VPN is also offered with an additional subscription fee. There is a day free trial. Norton with LifeLock keeps improving on its history as a top antivirus option with its PC maintenance features, making it the best for Windows computers. Norton introduced its first antivirus software in under the Symantec umbrella. Symantec purchased LifeLock in , and in , after the company's enterprise division was sold, the name was changed to NortonLifeLock.

The company is based in Tempe, Arizona. Norton with LifeLock won best antivirus for Windows because of how it has continued to build on its history of protecting Windows machines. The identity theft protection capabilities of LifeLock alone give this product an edge.

The amount of cloud storage increases based on the package level. Webroot SecureAnywhere for Mac offers excellent phishing detection and fast scanning ability specifically designed for Macs.

The company was founded in and introduced its first antivirus product in OpenText acquired the company in Webroot SecureAnywhere for Mac is our choice for antivirus protection that's best for Mac computers. There is still a belief that Mac computers are safe from cyberattacks, and while most viruses are targeted at Windows computers, Macs are vulnerable to other malware, ransomware, phishing attacks, and even Apple-targeted viruses.

This software boasts a very small footprint on your computer's operating system but offers very fast security scans and is one of the best at phishing detection.

Offering an email address when installing Webroot gives users alerts for new threats. For those who use both Windows and Mac, Webroot's interface is more similar across platforms than other antivirus software. The main difference is Webroot for Mac doesn't include a firewall. This price covers one device.

There is a day money-back guarantee. McAfee Antivirus Plus is our top choice for multiple devices because its subscriptions offer protection for every device in the home for a reasonable cost. McAfee Antivirus Plus is the one antivirus platform that recognizes the growing number of devices used in a single household, which could include four or more different operating systems.

The basic package supports up to 10 devices, support, secure web browsing, and antivirus. The MTP 10 Device plan is for one year for 10 devices, but also includes features such as full protection for the home network, password manager , encrypted storage, and identity theft protection.

Are you hoping the holidays will bring you a sparkly brand-new computer?

But the built-in protection typically expires in around three months, forcing you to pay for continued protection or select a different, better antivirus. There are plenty of choices, so many that you may have trouble deciding. Check out more security software deals available in Australia here. We call it antivirus, but in truth it's unlikely you'll get hit with an actual computer virus.

Malware these days is about making money, and there's no easy way to cash in on spreading a virus. Ransomware and data-stealing Trojans are much more common, as are bots that let the bot-herder rent out your computer for nefarious purposes. Modern antivirus utilities handle Trojans, rootkits, spyware, adware, ransomware, and more. As noted, PCMag has reviewed more than 40 different commercial antivirus utilities, and that's not even counting the many free antivirus tools.

Out of that extensive field we've named four Editors' Choice products, honored others with a four-star rating, and bestowed 3. If you have malware , one of the products listed in this article should take care of the problem. These commercial products offer protection beyond the antivirus built into Windows 10; the best free antivirus utilities also offer more than Windows does. However, Microsoft Windows Defender Security Center is looking better and better lately, with some very good scores from independent testing labs.

The combination of good lab scores and a great score in our hands-on malware protection test was enough to bring it up to 3. It doesn't appear in this roundup of commercial antivirus products, naturally. We take the results reported by independent antivirus testing labs very seriously. The simple fact that a company's product shows up in the results is a vote of confidence, of sorts. It means the lab considered the product significant, and the company felt the cost of testing was worthwhile.

Of course, high scores in the tests are also important. We've devised a system for aggregating their results to yield a rating from 0 to We also subject every product to our own hands-on test of malware protection, in part to get a feeling for how the product works.

Depending on how thoroughly the product prevents malware installation, it can earn up to 10 points for malware protection. Our malware protection test necessarily uses the same set of samples for months. To check a product's handling of brand-new malware, we test each product using a large collection of extremely new malware-hosting URLs supplied by MRG-Effitas , noting what percentage of them it blocked. Products get equal credit for preventing all access to the malicious URL and for wiping out the malware during download.

Some products earn stellar ratings from the independent labs, yet don't fare as well in our hands-on tests. In such cases, we defer to the labs, as they bring significantly greater resources to their testing.
