Let's face it… even though we're now two decades into the new millennium, having one of the best antivirus packages installed on your PC or laptop remains a necessity. After all, we're no closer now to vanquishing the cyber-criminals and hackers that plague the internet than we were a decade ago and it's far too risky to leave your laptop, phone and other tech without virus protection.
In fact, cyber crime has actually been growing significantly year after year, which means that it’s clearly more important than ever to ensure that your gadgets are afforded the protection of the best antivirus out there, whether that's free antivirus or paid.

1. Bitdefender Antivirus Plus 2020
Rock-solid and reliable protection
Operating system: Windows only | Maximum devices covered: 1 | Stand out features: Ransomware protection and remediation, privacy tools, VPN, Safepay
Get a 50-60% discount on Bitdefender Antivirus Plus 2020
TechRadar's #1 rated antivirus in a world packed with loads of virus protection providers, and doesn't even cost that much more than free antivirus downloads.
Note: For our Bitdefender Antivirus Plus review, we tested the 2019 version. This was updated and renamed to 2020 in July this year.
One at any rankings of big independent antivirus, and you’ll see that Bitdefender's premium security products always rise to the top.
Bidefender tends to be reliable and accurate in its virus detecting, boasting web filtering to block access to malicious sites, as well as a secure browser that keeps your online banking and shopping transactions safe. Plus, there's a password manager which auto-completes credit card details in web forms. It also scores high for its excellent anti-phishing module, which alerts you to malicious links in your search engine results and blocks access to dangerous sites.
That’s not all: there's also multi-layer ransomware protection that heuristically learns the behaviour of such threats to keep you safe as well as the ability to scan all your linked devices via the Bitdefender Central mobile app.
There are one or two issues – it grabs more resources than average, and might conflict with some programs – but Bitdefender Antivirus Plus is still a likeable package which offers excellent detection rates, great performance, and more than enough bonus features to justify the price.
Bitdefender Internet Security builds on AVP and triples the number of devices covered plus offers anti-spam, firewall, parental advisor and file encryption features.
For a little bit more you can purchase the Bitdefender Total Security edition. It adds all of the above and covers up to five PCs, Macs, Android and iOS devices.
Bitdefender Antivirus Plus 2020 | 1 year |
$59.99 $23.99 | 60% off
Not only is this one of the cheapest antivirus deals, it's coming from the world's best provider. Bitdefender Antivirus Plus come swith the added bonus of a VPN and Safepay as well as boasting multi-layer ransomware protection. This constantly tracks any malware and records the cyberthreat's pattern to keep you secure online.
2. Norton AntiVirus Plus
Protection that won't slow you down
Operating system: Windows only | Maximum devices covered: 1 | Stand out features: Advanced privacy security, financial security, global civilian intelligence network
Norton AntiVirus Plus is a top quality malware hunter that can automatically protect your PC all on its own.
The newly christened product was rolled out in April 2019 as a direct replacement for the aging Norton AntiVirus Basic. Moving from 'Basic' to 'Plus' definitely sounds better, but it really only adds a couple of extra functions - more on which will be discussed further down this article.
Norton touts plenty of tweaks, options and settings for those who require them, not to mention features like a handy URL blocker, which keeps you away from malicious websites. If that misses something, an excellent file reputation service heuristically recognises suspect downloads instantly. And, even if malware still finds a way through, intelligent behaviour monitoring uses its up to date virus definitions to quarantine threats at the first sign of trouble.
If you're more of a hands-on type, you can easily run scans on demand or even set up and save custom scans to check just the areas you need. Even schedule them to run at a particular time, but only if your system is idle, and it's not running on battery power.
So what exactly does Plus do that Basic didn't? There are only a couple of things really: it adds an extra 2GB worth of cloud backup and a password manager. The latter is worth having if you haven’t got one already, though it can't match the power of Dashlane and other market leaders.
There can be problems with some of the browser extensions. For example, we've found the Chrome version sometimes stops working for no apparent reason. We've seen plenty of reviewers reporting similar problems, so there does seem to be a real issue here.
That said, Norton AntiVirus Plus's main functions deliver on all fronts: it's easy to use, has the configuration options experts need, comes highly rated by the testing labs, and is meticulously designed to have the least possible impact on your system performance.

3. Webroot SecureAnywhere AntiVirus
The most lightweight programme around
Operating system: Windows and Mac | Maximum devices covered: 1 | Stand out features: Always-on security, identity protection, real-time anti-phishing, firewall monitor
Just about every antivirus tool claims to be ‘lightweight’, but Webroot SecureAnywhere AntiVirus is really the only one to deliver on this front. Installation takes seconds, the program files barely use 2MB of your hard drive, RAM footprint is tiny, and there are no bulky signature updates to tie up your bandwidth.
Considering this, there's no compromise on features, which makes it all the more impressive. Along with the core protection, there's smart behaviour monitoring, accurate real-time antiphishing, a firewall and network connection monitor, enhanced anti-ransomware, and other interesting bonuses.
It's not easy to compare Webroot's accuracy with the competition, as the big testing labs rarely evaluate the company's products. However, when they are reviewed, they generally score high, and our own tests show solid and reliable protection.
There's a lot to love about SecureAnywhere AntiVirus, and Webroot's 70-day 100% money-back guarantee suggests its confident in the product as well. If you're sick of overly complex and bloated engines, Webroot is a worthy contender for you.
4. ESET NOD32 Antivirus
Expert-level antivirus for the more experienced user
Operating system: Windows only | Maximum devices covered: 5 | Stand out features: Ransomware Shield, UEFI Scanner, Exploit Blocker, cloud powered scanning
If you judge antivirus software on the length of its feature list, ESET NOD32 Antivirus might be a bit of a disappointment. There’s no firewall, password manager, file shredder, vulnerability scanner or any of the bundled bonuses you'll often find in its rivals.
This doesn't mean the package is short on power, however. It's just more focused on the fundamentals. ESET NOD32 Antivirus comes with real-time malware protection, some of the best heuristic detection around, an anti-ransomware layer, exploit protection, URL filtering to block malicious websites, and modules to prevent attacks using PowerShell and malicious scripts.
A Device Control module limits the risk of infection from other devices by controlling access to USB sticks, external hard drives, optical storage media, even devices connecting by Bluetooth and FireWire. It's an unusual addition, but could make a difference if others are regularly plugging devices into your PC.
Just bear in mind that ESET NOD32 Antivirus isn't aimed at beginners. The interface is clumsy sometimes, some features are very advanced, and even the Help isn't always helpful.
Experienced users will appreciate ESET’s power and configurability, however. Above-average protection does a good job of keeping you safe, and a lightweight design ensures the package won't slow you down.
One of the fresh features in the latest update is the UEFI Scanner, which protects you from threats that attack your PC before Windows has even started.
ESET Internet Security builds on NOD 32 and triples the number of devices covered plus offers firewall, botnet protection, webcam protection, antispam and more.
Alternatively, you can purchase the ESET Smart Security Premium edition for not much more. It adds all of the above as well as password management and secure data.
- Best deal ESET Smart Security Premium (1 year, 1 device for $59.99)

5. F-Secure Antivirus SAFE
The most easy to use antivirus option
Operating system: Windows, Mac, Android, iOS | Maximum devices covered: 3 | Stand out features: Browsing and banking protection, Family Rules, ransomware protection
F-Secure Antivirus SAFE is a great collection of antivirus tools, and while it's a bit pricier than some of the other antivirus software on this best of list, the number of features you get certainly makes that high price tag worthwhile.
With F-Secure Antivirus SAFE, you get the brilliant antivirus software from F-Secure, alongside banking protection for safe online shopping, family safety tools and a device finder that lets you track your lost Android or iOS device, and if needs be, remotely lock or delete it as well.
The package typically receives maximum marks for protection from AV-Test, and generally scores highly with AV-Comparatives. They also say it can generate significantly more false positives than most of the competition, but how that affects you will vary depending on how you use your computer.
The interface is a major advantage, as it's extremely easy to use, lightweight, and for the most part, you can just leave the app to work alone looking after your PC. The program has minimal effect on your system performance, and if you do need to intervene, you can generally solve any issues in a couple of clicks.
In 2018, F-Secure Anti-Virus SAFE remains an appealing package: fast, lightweight, and able to run alongside many other security tools without conflict - you can read more about the company's offering with our F-Secure Anti-Virus review of its slightly lighter product.
6. Kaspersky Anti-Virus
Solid security for beginners and experts alike
Operating system: Windows only | Maximum devices covered: 5 | Stand out features: Automatic scans, drive-by cryptomining infection prevention, simplified security management
Kaspersky Anti-Virus is a stripped-back security package that focuses on the core security essentials: its web filtering blocks dangerous URLs, an accurate engine detects and removes threats, smart monitoring technologies track and reverse malicious actions, and that's pretty much it.
Fortunately, what you do get works well. Incredibly well. We've consistently found Kaspersky to be one of the best at blocking malware, and removing it from an infected system. That’s without mentioning that this anti-virus tool has regularly received top marks at sites like AV-Comparatives.
The program is easy to use, as well. An impeccably-designed interface has just the right number of buttons and options – not too basic, but not complicated or intimidating either – and there are plenty of on-screen instructions to explain how everything works. Even a beginner will be at home right away.
If you just need accurate, reliable and consistent malware protection, Kaspersky Anti-Virus will serve you well.
7. Trend Micro Antivirus+ Security
A strong contender
Operating system: Windows only | Maximum devices covered: 1 | Stand out features: Ransomware protection, advanced AI learning, email scam safeguarding, Pay Guard
Trend Micro Antivirus+ Security is a very capable package that's easy to use with above average antispam and an effective ‘Folder Shield’ module to block ransomware. And, it seems to get better as time goes on.
How good is it exactly? The top testing labs all rate it highly for protection, even though there’s a bit of disagreement on the details. In particular, AV-Comparatives says it gives a high number of false positives, which could be a real nuisance. On the other hand, AV-Test reports high levels of accuracy and no issues with false positives at all.
If there's a problem here, it's likely to be performance impact. PassMark's March 2019 Performance report assessed 14 security products on various performance-related benchmarks, and Trend Micro came towards the bottom part of the list.
Our experiences with the product are a little more reassuring: protection levels look similar to Bitdefender, false positives are only marginally higher, and the system itself doesn't slow down our system noticeably more than anything else.
We'd recommend running the trial for its full 30 days before you buy, then, to see if you notice any problems. But if you're unaffected, its high levels of detection and excellent bonus features make Trend Micro a good choice.
8. Panda Dome Essential
A user-friendly and very well-featured solution
Operating system: Windows only | Maximum devices covered: Unlimited | Stand out features: Process monitor, URL filtering, bootable USB rescue drive
Real-time malware detection, speedy cloud-based scanning, URL filtering to block malicious websites: Panda Dome Essential antivirus has all the essentials – not to mention, the goodies – you'd expect from the best antivirus software.
And, that's just the beginning. Panda Dome is brimming with added extras that some of the other plans on this list can’t match – from port scanning and ping handling to in-depth process monitoring and an integrated VPN.
When it comes to the main event – virus protection – there's not a lot of Panda test results from the independent labs around right now. However, the figures we've seen don't exactly fill us with confidence as Panda came towards the bottom of the pile according to AV-Comparatives. This doesn't mean that Panda Dome will put your devices in harm's way, but you can understand why we'd recommend other providers over it on this basis.
The interface will be a little bit decisive, too. With so many weird and wonderful features included, Panda Dome does a very capable job of making sure that they can all be accessed and you can go as in-depth as you need. However, on the other hand, this might put off users who just want a quiet, simple antivirus package.
One undoubted advantage here is the price - Panda Dome Essential is one of the best value programs out there. And, you even have the option of paying a little more and upgrading to cover an unlimited number of laptops, phones, tablets and desktops with a single subscription.

Best free antivirus downloads
Paying for a premium service means you get more features like spam filters, parental controls, system scans and advanced firewalls. This makes them more suitable for power users, those who want a bit of extra security and anyone who needs their system to run as smoothly as possible.
It also means you avoid annoying pop-ups that try and tempt you to upgrade to the full version. And, as you've discovered above, they won’t cost you an arm and a leg.
In fact, these days you can get top quality protection absolutely free, with just about every single major vendor out there offering a free antivirus. By doing so, developers gain access to more devices from which they can collect data, and therefore improve their knowledge and security platforms so it’s really not in their interest to reduce the amount of protection provided by the free version.
Windows has come a long way in terms of security, but it's still fair to say that Windows 10's built-in solution, Windows Defender, is the last free AV app you should trust to keep your system clean.
If you're determined to get free antivirus, we strongly suggest that you check out our picks for the best security downloads in 2019 below. We've highlighted their features and shortcomings as well in order to ensure that you pick out the most ideal one for you and your needs.
Best free antivirus 2019 at a glance
- Bitdefender Antivirus Free Edition
- Avast Free Antivirus
- Sophos Home
- Kaspersky Free
- Avira Free Antivirus
1. Bitdefender Antivirus Free Edition
The best free antivirus scanner in 2020
Operating system: Windows, Mac, Android | Version: 2018 | Features: Phishing protection, Behavioural analysis, Automatic scanning
Essentially consisting of the AV section of the full product, Bitdefender Antivirus Free Edition's clean, light, well constructed scanning mechanisms – which are almost universally faster than the industry average – and unrivalled virus definitions mean Bitdefender is back at the top of the free tree.
The free version's insistence on running in autopilot mode is a double-edged sword, making the process of virus management easy but taking it out of the user's hands; while we're inclined to trust it, there have been cases in the past of automatic systems going slightly rogue, such as the incident a few years back when Panda Antivirus identified itself as a virus and locked up a large number of Windows systems.
AV-TEST's testing did pick out a few flaws in its handling of zero-day threats, however. And it's worth pointing out that for you can currently get our top rated paid-for solution - Bitdefender Antivirus Plus - for the equivalent of around $2 per month. That's a tiny amount to pay for a tonne of extra features, such as online banking protection, integrated password manager, permanent file shredder and and free online 24/7 support.

2. Avast Free Antivirus
A much-improved free antivirus suite
Operating system: Windows, Mac, Android | Version: 17 | Features: Virus detection, Gaming mode, Password manager, Malware scanner
Avast and AVG haven't yet fully merged, despite the former formally acquiring the latter in mid-2016. The newly combined company says the two free antivirus products will remain separate, although there's apparently a joint AV package on the way soon. Obviously, though, Avast now has a lot more data to work with, having expanded its effective userbase (and, therefore, its threat detection network) to a whopping 400 million users.
The latest edition of Avast Free Antivirus adds an automatic gaming mode to mute popups and reduce system load when you're firing up a processor-hungry game, which is very handy indeed, and the interface has been given a clean new overhaul. There's a password manager, too, which is an undeniably good addition to your security portfolio.
It scores well on AV-TEST's widespread malware benchmark and continues a clean sweep against 0-day attacks – presumably that expanded detection network is really helping. Less impressive is the slight negative effect Avast has on software launch times, and its slightly popup-heavy attitude.

3. Sophos Home
The perfect choice for a home full of PCs
Operating system: Windows, Mac | Version: 17 | Features: Virus detection, Phishing protection, Parental controls, Protects up to 10 PCs
Marketing itself as "business-grade security", Sophos Home does a little more than most free antivirus software, and actually seems better suited to families.
You get standard virus protection and anti-malware protection, along with browser tools like anti-phishing and, most importantly, content control. Combined with central management of up to 10 PCs, this means you can effectively lock down your kids' browsing options.
Although AV-TEST hasn't formally assessed Sophos' skills, fellow lab AV-Comparatives offers a decent rating of its abilities.
Although Sophos Home has always had desktop notifications, there was no premium version of the software for it to encourage an upgrade to. That changed in February with the launch of Sophos Home Premium.
Review and where to download: Sophos Home
4. Kaspersky Free
Kaspersky's first foray into free internet security
Operating system: Windows | Version: 188.8.131.525 | Features: Real-time scanning, Anti-phishing, Email scanning, Spyware protection
The paid-for version of Kaspersky's Windows security software frequently tops charts of best virus prevention solutions and AV-TEST once again gave it full marks across the board in its latest round of testing.
As you would expect, Kaspersky Free is a scaled down version of the full program - a tool that we really like (more on which below). The free version ditches additional features such as privacy protection and safe payment sandboxes to concentrate on powerful, no-frills and - most importantly - free protection for your PC. The result is a tremendously easy to use and navigate bit of software that does an effective job of keeping you protected from viruses.
Using the nuts and bolts real-world scanning engine of the paid-for suite, Kaspersky Free is fiendishly hard for viruses and trojan horses to break down. And we love that it doesn't constantly pester you with nudges to upgrade to the full version.
But, ironically, we will just for a moment, because Kasperksy Anti-Virus 2018 isn't expensive to buy and yet affords much better protection to your PC (or PCs). The standard price is $29.99 to protect three computers and includes more muscle when it comes to preventing ransomware, spyware and Trojans.

5. Avira Free Antivirus
Great antivirus, but a little noisy for our liking
Operating system: Windows, Mac, Android, iOS | Version: 2018 | Features: Virus detection, Phishing protection, Built-in VPN, System optimization tools
Avira Free Antivirus for Windows continues to score highly on AV-TEST's stringent testing program, quashing 99.7% of tested threats, and it generally doesn't put too big a burden on your hardware.
It has a clean, friendly interface - with a swish redesign ready for 2018 - and throws up minimal false positives. The introduction of a free security suite to optionally run alongside it – with ransomware and phishing protection, a 500MB/month VPN and various speedup promises – just sweetens the deal. This is one of the best free antivirus packages of 2018.
So why, then, have we dropped it from the top spot on our list, a position it's held for the past two years? It's the constant badgering. There's a certain level of popups and advertisements that's acceptable for a free product, and Avira has begun to cross the line. It's not as onerous as some – Comodo's over-enthusiastic interface comes to mind – but booting up your PC to see Avira shouting at you once again is jarring.
Review and where to download: Avira Free Antivirus
Best business antivirus
Each entry in this list has been carefully chosen for its business features, such as remote installation and central management. The best business antivirus software will have enterprise-level protection against threats, but that doesn't mean they have to cost a lot of money, either. The price per installation can sometimes be cheaper than even our recommended best antivirus packages.
An excellent business antivirus suite, giving you various tools such as virus protection, Firewall, email protection, anti-spam and the ability to sandbox applications for complete security. Avast Business Antivirus Pro (as opposed to the standard Avast Business Antivirus) also includes Sharepoint and Exchange protection, as well as a number of tools for your servers.
Symantec's first benefit is the company's Insight file reputation technology, an effective way to detect and block even the very latest undiscovered threats. Other layers of protection include virus protection, behaviour monitoring, intrusion protection, a firewall, and the 'Power Eraser' to remove stubborn threats and repair your system.
This package makes reliable protection its top priority. Bitdefender products are loved by the independent testing labs, highly rated for malware detection, removal, performance and usability. Most of the features work automatically – anti-malware, firewall, web advisor, URL filtering – but you can also customise the product to control user actions.
This is Avira's main small business product. It takes all the core features you'd expect – antivirus, baseline network protection, web filtering – and extends them with file server protection and optimisation, along with application whitelisting and blacklisting.
A small business product, which comes ready to protect Windows PCs, file servers, Android and iOS devices. The desktop side of the package has all the usual quality Kaspersky modules – antivirus, antispam, a firewall, more – but the mobile security technologies are even more impressive.
- Even if you own the best computer in the world, you're still at risk
