Big target

Windows 10 is the most widely used desktop operating system in the world, and as the OS of choice for many PCs everywhere, it represents a broad and juicy target for malware authors.

unwise folks who remain on Windows 7) are the biggest targets for malware authors.

Now, it’s true that in recent times, malicious actors are giving Apple’s Mac platform more attention, but Windows is still the operating system which is most under threat, of course. Particularly when it comes to malware, with Mac threats tending to be the likes of potentially unwanted programs (known as PUPs) or adware. The vast majority of the really malicious stuff is hurled at Windows machines.

Threat level

Going by the latest ‘state of malware’ report covering 2019 from Malwarebytes [PDF], the amount of malware detections may be remaining at the same level as the previous year, but it’s still a large quantity – and what’s worrying is that these threats are becoming more sophisticated in general. (Note that other security outfits have pointed to a growth in malware over the course of 2019, like Kaspersky).

Clearly, there’s no shortage of perils out there online, with Malwarebytes observing that adware and Trojans (apps that look like legitimate programs, but deliver a malware payload) remain a major problem for Windows machines. Furthermore, there’s a disturbing increase in the use of ‘HackTools’, which as the name suggests are tools facilitating hacking into PCs, and are now being used against consumers (rather than just businesses), with a 42% year-on-year increase.

The likes of ransomware remain a threat to your files, exploiting crises in the real world to try to trick unsuspecting users, and so broadly speaking, the nature of Windows 10 as a big target for malware, and the growing sophistication of threats are good reasons why you should bolster your PC’s defenses with a good antivirus.

Windows Defender?

So, having established the need for an antivirus on Windows 10 – and elsewhere, we’ve addressed the broader question of whether antivirus software is necessary at all in 2020 (the answer being ‘yes’, in a word) – let’s come onto another point that some folks might argue.

Namely that with Windows 10, you get protection by default in terms of Windows Defender. So that’s fine, and you don’t need to worry about downloading and installing a third-party antivirus, because Microsoft’s built-in app will be good enough. Right?

Well, yes and no. Windows Defender used to be something of a laughing-stock in security circles, but all that’s now in the past. The Defender of today is actually a robust app that can indeed defend your PC true to its name, and has actually achieved some impressive rankings in the reports from independent test labs.

However, the truth is that while Windows Defender is a solid enough solution you can rely on, there are third-party antivirus apps which offer more functionality, and are still free – they just take a little effort to install.

So if you can take a little time out, it’s worth installing one of the leading free antivirus apps to replace Windows Defender in order to get more features and better security still – and indeed avoid a potential fly in the ointment in terms of Microsoft breaking Defender, which has happened a couple of times in the recent past.

It’s also worth considering that if you want to considerably beef up the levels of security on your PC with extra layers of defense like anti-ransomware shields or added web browsing protection, you might even want to consider a paid antivirus.

Do I really need antivirus for Windows 10?

Whichever way you dice it, it would seem to be a wise choice to get an antivirus for Windows 10, and make the effort to upgrade from the default levels of security provided by Windows Defender. After all, it’s easy enough to grab a decent free app to help keep you even safer online.

‘People use smartphones more but invest less in their security’: New report claims McAfee and Norton remain the most loved antivirus brands as users ditch lesser-known security products for free tools like Microsoft Defender or Apple Xprotect

  • Most smartphone users rely on built-in security without additional protection
  • Paid antivirus adoption on mobile devices continues to decline steadily
  • A significant share of users remains unprotected or unaware of safeguards

Most Americans now use their smartphones more than their computers, but very few spend money to protect those phones from hackers, new research has claimed.

A Cybernews report surveyed over 1,000 American adults, and found only 18% of mobile phone users pay for third-party antivirus software.

Built-in tools like Microsoft Defender and Apple’s XProtect have become the default choice for most people, while McAfee and Norton lead the paid market for the second year in a row.

Smartphone owners are skipping extra security protections

Most consumers believe the security features already built into their phones are sufficient for daily use, and see little reason to spend extra money on something they think they already own for free.

Roughly 14% of mobile users say they have no cybersecurity tools installed at all on their devices. Another 16% cannot even name what protections they currently have in place.

On desktop computers, the situation looks very different, with far fewer unprotected machines and much wider adoption of third-party security tools.

Windows Defender and Apple’s native security features now serve as the primary defense for 53% of computer users and 51% of mobile users.

Most people choose these free options because they trust the operating system vendor to provide adequate baseline protection.

Paid antivirus adoption on computers has actually grown by 2% since last year, reaching 41% of users.

On mobile devices, however, third-party antivirus usage has dropped by roughly 10% over the same period, falling from 28% to just 18%.

Mobile users face growing risks

Ransomware attacks targeting smartphones are still less common than those aimed at computers, but the threat landscape is shifting rapidly.

Users who depend solely on the free security tools that came with their phones may be underestimating what modern cybercriminals can do.

Paid subscriptions have gained ground over free alternatives, yet the majority of mobile owners still avoid spending money on dedicated protection.

Cybercrime exposure does influence some users to change their habits, but personal experience is not the main driver of adoption for most people.

Many users employ layered security approach, combining antivirus with VPNs and password managers.

However, the data shows that a large segment of mobile users remain either unprotected or unsure about what safeguards they have.

Established brands like McAfee and Norton continue to benefit from user trust, while lesser-known products struggle to gain acceptance even when their features are comparable.
