Make Everyday Digital Life More Secure

Current security software does more than identify familiar computer viruses. Many tools also check for ransomware, spyware, trojans, harmful downloads, phishing activity, unwanted programs and unusual device behaviour.

1. Maintain active protection: Choose a trusted security product that receives threat updates and can monitor activity in real time.
2. Install updates promptly: Updates to your operating system and security tools help address weaknesses that criminals may exploit.
3. Check unfamiliar downloads: Scan unexpected attachments and questionable files before you try to open them.
4. Avoid imitation tools: Download security applications from the developer or a recognised official store.
5. Combine sensible safeguards: Antivirus is only one layer; safe browsing, account protection, software updates and secure networking also matter.

Windows 11 provides several security features out of the box. Begin by checking these built-in controls and keeping them enabled before deciding whether extra software is necessary.

• Microsoft Defender Antivirus: Provides real-time, cloud-assisted and behaviour-based malware protection.
• Windows Security: Brings antivirus, firewall, account and device-security controls into one place.
• Microsoft Defender SmartScreen: Helps protect against phishing sites, malicious Files and unsafe applications.
• Smart App Control: On supported Windows 11 systems, it helps prevent untrusted or potentially harmful applications from running.
• Ransomware protection: Features such as Controlled Folder Access can help protect important files from unauthorised changes.
• Hardware-backed security: Secure Boot, TPM 2.0 and other platform protections are important parts of modern Windows security.

Apple computers include several protective technologies, yet they can still face malicious software, phishing, unsafe browser extensions, stolen passwords and targeted threats. Regular macOS updates and careful use of its privacy and security settings remain important.

• Get macOS updates: Security updates are one of the most important protections against known vulnerabilities.
• Gatekeeper: Helps control which applications can be opened and protects against untrusted software.
• XProtect: Apple's built-in malware protection helps detect and block known malicious software.
• FileVault: Encrypts the Mac's startup volume to help protect data if the computer is lost or stolen.
• Privacy & permissions: Review which apps can access files, cameras, microphones, contacts and other sensitive resources.
• Lockdown Mode: An optional high-security mode intended for people who may face highly sophisticated targeted attacks.

Smartphones store personal photos, conversations, passwords and financial details, and often provide access to many other accounts. Protecting a phone is therefore an essential part of staying safe online.

• Android: Keep Android and Google Play system updates current and leave Google Play Protect enabled.
• Safer app Use: Be careful with APK files and apps from unknown sources. Advanced Protection can provide additional restrictions on supported Android devices.
• iPhone & iPad: Keep iOS and iPadOS updated, use a strong device passcode and review account and privacy settings.
• Stolen Device Protection: On supported iPhones, this can add additional safeguards when the device is away from familiar locations.
• Lockdown Mode: Available for people who may be targeted by highly sophisticated attacks; it deliberately limits some device functionality.
• Messages & links: Never assume a message is safe just because it appears to come from a known person or company.

The router connects your home devices to the internet. Configuring it carefully can make unauthorised access less likely and help contain risks from a compromised device.

1. Change default credentials: Replace default router administrator passwords with strong, unique credentials.
2. Use modern Wi-Fi security: Prefer WPA3 where supported; otherwise use a strong WPA2 configuration.
3. Update router firmware: Check the manufacturer's security and firmware updates regularly.
4. Secure remote administration: Disable internet-facing router administration unless it is genuinely required.
5. Separate sensitive devices: Consider guest or separate network segments for visitors and less-trusted smart devices.
6. Review connected devices: Remove unknown devices and investigate anything you do not recognise.

Security products are updated often. Our articles explain their main purpose, compatible systems, safe setup practices, useful options and situations where combining products may cause problems.

• Microsoft Defender: Windows protection and Microsoft Defender coverage across supported devices.
• Malwarebytes: Malware detection, removal, web protection and additional security layers for supported Windows and Mac systems.
• Firewall tools: Understanding Windows Firewall, macOS firewall controls and router-level filtering.
• Password managers: How password vaults, passkeys and multi-factor authentication reduce account takeover risk.
• Browser protection: Safer extensions, phishing protection, privacy settings and secure browsing habits.
• Backup tools: Why offline or otherwise protected backups are important against ransomware and device failure.

A warning does not always prove that a device has been infected. Begin with cautious, basic checks and avoid interacting with suspicious prompts:

Is extra antivirus software necessary on Windows in 2026?

Not always. Windows comes with Microsoft Defender Antivirus and additional safeguards. Another product may offer useful features, but running two incompatible real-time antivirus tools can cause issues.

Should Mac users install antivirus software?

macOS has built-in security features, yet phishing, harmful downloads and malware remain possible. Keep the system updated and consider extra software according to your needs and risk level.

Can Android users rely on Google Play Protect alone?

Play Protect provides an important built-in malware defence, including checks for apps. It should be combined with current security updates, careful app usage and strong account security.

Can an iPhone be considered completely secure?

No device is entirely risk-free. Even with strong iPhone protections, deceptive links, account compromise and targeted attacks are still concerns.

Is it a good idea to run two antivirus tools?

Usually not for two products providing always-on real-time protection. They can interfere with each other or cause performance and connectivity problems. Check the vendors' compatibility guidance before combining security products.

When should I update my security software?

Install updates as they become available. For most people, enabling automatic updates for the operating system, browser and security applications is the simplest approach.
