Bitdefender's Total Security offering for 2018 is a feature-packed product that's ideal for the security conscious, the family, and the traveller.

Included in the price tag for 5 devices (which can include Windows, Mac OS, Android and iOS) you get all the usual protections, plus a password manager, a parental advisor, and a 200MB per day per device VPN.

Along with the usual file and system scans, there is a dedicated vulnerability scan that checks for outdated software and weak network passwords.

It also offers protection from new and emerging threats, such as ransomware. Ransomware has proven to be a huge threat, but Bitdefender 2018 uses a double-layer defence against the newest of its kind.

At the time of writing, Bitdefender was knocking £30 off the price of Total Security, making it seriously good value at just £39.98 down from £69.99. UK readers can take advantage of that deal here.

In the US, it's $89.99, and is available to buy here.

Norton Security Deluxe is a slick product that has the feel of Symantec's impressive next generation business-oriented products. We'd highly recommend it.

It's discreet, benefiting from its parent company's technology and cloud support. Norton also makes a "100% virus promise" that an expert will keep your devices virus-free or your money back. Backing all this, the Norton Studio app allows you to control all protected devices from a single Windows machine.

You'll get Browser Protection included, as well as a password manager, Scam Insight and performance tools to help speed up your computer.

The price of this protection weighs in at £69.99/$97.95 for 5 devices, though hefty discounts are available throughout the year from the Norton website. At time of writing, it's £29.99/$49.99 for a year.

ESET has a deceptively simple interface that hides a genuinely impressive and detailed tool set. Delightfully affordable, it is among our favourite antivirus options for PC.

With a raft of features, it offers great value for money. The Syninspecter tool, for example, shows you a complete yet manageable rundown of your entire system's security status. There's also a social media scanner, anti-theft tools, a Home Network Protection tool, banking and payment protection and lots more.

One small downside is that there is currently no explicit ransomware module in the interface, however it does provide excellent protection from ransomware under the hood.

You can get ESET Internet Security for £39.99 here. If you're in the US, it'll be $49.99 from here.

You'll get a file shield, web shield, a built-in firewall, a ransomware module and other layers of defence to keep your computer protected from all angles.

Plus, there are several types of system scan including a dedicated USB / DVD analysis.

  • Reviewed on: 10 May 2018

At first sight, there's little to choose between Kaspersky Security Cloud and Kaspersky Total Security. All the main antivirus tools required are in noth products, making them both options worth considering. 

What's significant about Security Cloud is that it contains patented adaptive security tech that automatically adjusts your settings based on your current activities.

It helps you detect unauthorised devices and dodgy websites, as well as helping you make stronger passwords and manage those passwords safely.

It can also help you avoide adware like browser toolbars, and you'll get mobile antivirus included.

At time of writing it's just £34.99/$89.99 for three devices for a year. The family option offers 20 accounts, and is £69.99/$149.99 per year.

You can find out more and sign up here if you're in the UK, or here if you're in the US.

BullGuard Premium Protection 2018
  • Rating: ratingsratingsratingsratingsratings
  • Reviewed on: 11 December 2017

Designed to beef up protection for home networks, Bullguard Premium Protection 2018 has a network scanner to protect any internet connected device in your home, in additon to the expected malware detection, a vulnerability scanner and more feautres to help secure your PC.

An identity protection feature searches the web for leaked details, owhile a parental control module helps you keep an eye on your children's use of mobile devices.

There's a game booster to block popups and optimise CPU performance, as well as a PC tune up facility that will be useful to non-gamers too.

The interface is a bit on the technical side, with lots of scan types, options and settings, and there's no dedicated anti-ransomware module which is a shame.

It costs a reasonable £69.96/$99.95 for a whopping 10 devices. There are lower priced options available for less devices but they miss out on some features.

  • Reviewed on: 27 April 2018

Avast Premier 2018 has a lot going for it, and is certainly user friendly, but we found that the constant opportunites to upgrade functinality you can get free elsewhere, plus the intrusive ads on the mobile version, make it look overpriced compared to rivals.

It's £59.99/$79.99 for one PC, which feels high considering what's not included. You won't get the password manager, cleanup tool or the AntiTrack privacy service.

You will, however, get a firewall, several scan types and a very welcome ransomware shield, as well as a file shredder and web protection tools, so despite the initial misgivings it is still surprisingly good.

Get Avast Premier for £59.99 here, or $79.99 here.

  • Rating: ratingsratingsratingsratingsratings
  • Reviewed on: 23 May 2018

Total AV Pro 2018 is an antivirus suite that shares many of its features with others listed here, plus some welcome extras. There are some features missing, though, and the renewal price is very high so we'd advise customers to watch out for that.

You'll be able to run a quick scan or a more in-depth system scan, and will also get system performance boosting, disk cleaning, web security and a password manager, all of which we found useful.

ID Protection monitors your web presence and is a great additional feature, but it's not currently available to UK customers, and there's no parental control or anti-theft functionality here. There's also no right-click scanning or shredding of files, and no explicit ransomware module.

The price for the first year compares well with rivals, at £39.95/$39.95 for three devices, and you can buy it on the Total AV website here.

  • Reviewed on: 1 March 2018

F-Secure Safe 2018 is an antivirus solution aimed at families. It has a small but essential set of useful features, but we found that some technical difficulties made it tricky to use.

We had trouble running the cleanup tool and the VPN, and the browser protection add-on isn't enabled by default. 

Beyond that, though, there's a small but essential box of tricks here. The Deep Guard tech has a next generation feel that goes some way to make up for technical problems, and the Family Rules module allows you to set sensible screen time limits for your kids.

Web protection is good, and there are anti-theft features too.

You can get F-Secure for 3 devices for £59.99/$69.99 per year. Sign up for F-Secure Safe 2018 here.

Your buying guide to the best antivirus 2018

Antivirus software detects, and then prevents, disarms or removes malicious programmes or malware, often referred to as viruses. Antivirus doesn't offer a perfect solution to the problem of malware, but it's a critical first step to securing your machine. It's also important to keep that software updated.

But internet security software is no longer just about countering viruses. Although they still exist, viruses are arguably a minor part of the malware now prevalent on the web.

More important now is security of personal data and protection from ransomware. Security exploits aren't about show-off hackers massaging their egos, anymore, but about monetising their malware.

The modern day criminal doesn't have to be a hard-line hacker, either. They can buy all the software they need, and millions of addresses, on the dark web or even on eBay, if they know where to look.

Zero day attacks

Malware is evolving faster than ever, but fortunately the latest generation of antivirus - or AV - is better equipped than ever to handle new threats.

Although the primary concern is to block malware so it doesn't install on your PC in the first place, there isn't an internet security suite made which is 100% effective.

That said, worthwhile internet security and antivirus software should also detect so-called 'zero day' attacks, where the malware is so new it hasn't yet been analysed or had 'signatures' build into internet security protection routines.

The speed with which these analyses are made is an important factor in the level of protection an internet security suite can provide. Some companies now claim a turnaround of well under an hour, using information gained from their own customers about similar attacks.

The cloud element in security applications is growing more and more important in speeding up this process. Some products are now using behaviour analysis and even artificial intelligence to make things quicker and more reliable.

Newly-installed software can be monitored, looking for suspicious activity and can be prevented from potentially damaging actions, such as changing registry entries or installing any browser add-ons. Ransomware can also be identified by unexpected attempts to encrypt your files.

How we test antivirus software

Every program on this list is worth your investment. The differences between the top few are relatively minor. The critical thing is to install one of them.

We test them by teaming up with the UK's SELabs, as well as Germany's AV-Test.org, both highly respected independent security-software testing labs. Each rigorously tests AV products from a number of leading security companies.

The multifaceted testing procedure looks not only at how well an AV product can detect malware using traditional, largely signature-based methods (that is, employing a database of known malware types), but also how well it can block brand-new, unknown malware caught fresh from the wild. These companies also examine how well security products clean up after an infection if a piece of malware does get through.

Our tests focus on paid-for AV products, but there are some free options available. Paid-fro AV products usually offer better technical support and more comprehensive protection features than free programmes, but free is free and some free packages can still give paid packages a run for their money. Internet security suites go further still, offering firewalls, parental controls, identity theft protection and more.
