Gives you handy extras like a firewall and remote wipe

Call blocking
Anti-theft feature

Antivirus giant, Avast, has used its considerable skills to create an app which goes above and beyond a mundane scanner. Extra features in the free version include a call blocker, firewall and even an anti-theft measure allowing you to remotely lock or wipe your Android device if it goes missing.

The app used to be paid but is now free, supported by ads. You can pay a small monthly or yearly premium to remove these. Another very useful premium feature is ‘in-app locking’ whereby your device will ask for a PIN before opening certain apps. This prevents malware from launching apps such as internet banking automatically.

‘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

Copy link Facebook X Whatsapp Reddit Pinterest Flipboard Threads Email Share this article 0 Join the conversation Follow us Add us as a preferred source on Google Newsletter Subscribe to our newsletter Most smartphone users rely on built-in security without additional protection Paid antivirus adoption on mobile devices continues to decline steadily A significant share


  • 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.
