Antivirus: Do you still need it?

Purchasing antivirus software is often seen as necessary but can be frustrating, especially with built-in security features available on most computers. Windows includes Microsoft Defender Antivirus, which has been independently tested and scored well for protection, performance, and usability. Mac users have XProtect for malware detection. Users should verify that their existing protection is enabled and up-to-date before considering a subscription. Antivirus programs combat various types of malware, using methods like signature scanning and heuristic analysis, but they are not infallible. Research on antivirus effectiveness varies, with scores reflecting different criteria and not universally applicable detection rates. Subscriptions may be worthwhile if they offer specific features, but users should be cautious about renewal prices and unnecessary multiple installations. Maintaining updated software and practicing good security habits are essential for protection. For everyday use, built-in protection is often sufficient unless additional benefits justify the cost of extra software.

The Best Antivirus Software of 2026: Do You Even Need It?

Antivirus software is evolving as operating systems like Windows 11 and macOS now include robust built-in security measures, reducing the necessity for standalone antivirus solutions. Windows 11 features Microsoft Defender Antivirus, while Macs and Android devices have their own built-in protections. Independent tests show that Microsoft Defender achieved a perfect score in AV-TEST's April 2026 evaluation and performed well in AV-Comparatives' tests. Key antivirus solutions in 2026 include: - Bitdefender Total Security for individuals seeking paid protection. - Microsoft Defender for Windows users wanting free protection. - Norton 360 Deluxe for families, offering comprehensive features. - Avast One as a free third-party protection option. - Bitdefender Antivirus for Mac users seeking extra protection. - Google Play Protect for Android users. Choosing the right antivirus solution depends on factors like device type and user habits. While Microsoft Defender offers solid protection, users seeking comprehensive security may prefer Bitdefender or Norton 360 Deluxe. Avast One is a viable free alternative. Antivirus software cannot prevent all threats, emphasizing the importance of good security habits, such as keeping systems updated and using strong passwords. Modern antivirus solutions are designed to minimize impact on system performance.

HSBC decides Samsung Secure Folder and Android’s Private Space are no place for a banking app

HSBC has restricted its Android app from functioning within Samsung's Secure Folder and Android's Private Space, causing many customers to lose access to online banking services. The bank described this as a "proportionate security control" to mitigate risks, stating that customers must use the app outside these environments. Feedback from users has been largely negative, with complaints about abrupt access loss and inadequate communication regarding the changes. Customers are unable to utilize web banking due to the app's requirement for multifactor authentication, and some have raised concerns about HSBC's compliance with the Financial Conduct Authority's Consumer Duty. HSBC has advised customers to access the app outside of protected spaces and mentioned the option of using a Physical Secure Key for desktop banking.

Are Free VPNs for Android Actually Worth Using

A free VPN for Android can improve internet privacy, especially on untrusted networks, but it has limitations, such as not guaranteeing complete anonymity or security. The VPN creates an encrypted tunnel between the device and the server, protecting traffic from local monitoring but not ensuring overall security if poorly implemented. Changing your IP address does not guarantee anonymity, as account logins and tracking technologies can still identify users. Free VPNs may be suitable for low-risk tasks, like occasional browsing on public Wi-Fi, but they do not protect against malware or phishing. Providers often rely on alternative revenue sources, such as advertising or data sharing, which necessitates careful examination of their privacy policies. Free VPNs may have limitations like data caps, slower speeds, and fewer server options compared to paid services. Users should evaluate the provider’s background, privacy policy, permissions, and performance before installation. A paid VPN generally offers better reliability, support, and transparency, making it a safer choice for sensitive activities.

What a smart firewall does and why it matters on home Wi-Fi

Home Wi-Fi connects various devices and presents security risks, making firewalls important for network protection. A router firewall is built into the home router and protects all connected devices, while a software firewall operates on individual devices for additional security. Inbound traffic is data coming to a device, while outbound traffic is data leaving it; firewalls analyze this traffic to manage connections. Network security is critical as sensitive information is often accessed on devices used for leisure, and remote work increases data overlap. Firewalls can control network connections and filter unwanted traffic but cannot replace weak passwords or antivirus protection. To enhance home network security, users should secure router settings, keep routers updated, strengthen Wi-Fi access, check connected devices, and replace outdated routers. A comprehensive security strategy includes keeping software updated, using multifactor authentication, being cautious with links, and strengthening firewalls with antivirus protection. Protecting valuable data is essential, and understanding ransomware risks is crucial. The 3-2-1 backup strategy involves maintaining three copies of data on two different storage types, with one copy offsite. Regularly testing backups and knowing how to respond to ransomware incidents are also important.

NordVPN has enhanced its VPN application by integrating antivirus features, evolving into a comprehensive digital privacy and security service. The revamped app is based on three pillars: Connect, Protect, and Monitor, offering tools such as VPN services, scam and phishing protection, and Dark Web Monitor. NordVPN's approach aims to intercept threats early, focusing on deception tactics used in modern scams. The company's next-generation antivirus system uses a dual-layer detection strategy, evaluating URLs in real-time and scanning files for malware. In April, NordVPN blocked 4.8 million threat events, including malware and phishing attempts. The company emphasizes minimal data collection for threat decisions and offers three subscription tiers: Basic, Complete, and Prime, each with a 30-day money-back guarantee. Users are reminded that no app can fully protect against cybersecurity threats, and best practices like strong passwords and multifactor authentication are essential.
