How to protect your PC from malware

Malware, short for "malicious software," is designed to gain unauthorized access to computers or networks for purposes such as data theft and surveillance. It can be introduced through disguised software or deceptive links. To protect against malware, it is essential to install antivirus software, scan external drives before connecting them, be cautious about downloads, avoid suspicious websites and emails, update applications regularly, enable Tamper Protection on Windows, minimize file sharing, enable Firewall protection, watch out for phishing attacks, and back up data regularly. The future of malware protection may involve leveraging artificial intelligence and machine learning to enhance detection and analysis of threats.

VPN threat protection vs. dedicated antivirus: Are VPNs really enough?

Many VPN providers are now offering additional security features such as malware detection, malicious link checkers, and ad blockers, alongside their primary function of encrypting internet traffic. Notable VPNs like NordVPN and Surfshark have integrated real-time malware protection, with NordVPN becoming the first VPN to receive certification as a reliable anti-phishing tool in 2024. Surfshark's Surfshark One package offers comprehensive real-time protection from viruses and malware. Other VPNs, such as Avira and CyberGhost, utilize shared infrastructures for antivirus capabilities, which can lead to delays in updates and inconsistent platform support. Microsoft Defender has improved significantly, blocking 95.5% of live threats according to AV-Comparatives, while Apple employs multiple defenses in macOS, including Gatekeeper and XProtect, to manage malware threats. Avast Free Antivirus has achieved a perfect 100% block rate in recent testing but comes with limitations compared to paid antivirus suites like Norton 360 Deluxe and Bitdefender Total Security, which offer additional features such as password managers and identity monitoring. A layered approach to digital security, combining a VPN, free antivirus, and built-in OS-level security, is recommended for effective protection. Relying solely on one layer leaves potential gaps, as a VPN cannot detect existing malware, and free antivirus solutions may lack advanced features. Users managing sensitive data or frequent financial transactions should consider investing in premium antivirus suites for enhanced security.

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.

In terms of performance, Norton showed a 2-3% FPS decrease in Cyberpunk 2077, while Bitdefender's impact was only 0-2%, and Malwarebytes had less than 1% impact. Norton and Bitdefender are tied in detection capabilities, both scoring 18/18 in AV-TEST, while Malwarebytes had a 92.4% offline detection rate and 98.3% online. Norton includes a no-log VPN and gamer-tag monitoring, while Bitdefender offers identity protection without specific gamer-tag monitoring. Malwarebytes lacks a VPN and password manager. Pricing varies, with Norton starting at .99 for three devices, Bitdefender at .99 for one device, and Malwarebytes at .99 for one device. To switch antivirus solutions, users should back up their license keys, use removal tools, and ensure game-aware modes are active.

Microsoft’s Two-Track Patch Tuesday: Cloud Identity Flaws Fixed Before Disclosure, Windows Still Catching Up

The September 2026 security cycle revealed a bifurcated approach to vulnerability management by Microsoft, focusing on cloud-side identity services with silent mitigations and traditional Patch Tuesday updates for on-premises Windows infrastructure. On September 3, Microsoft addressed nine cloud-side vulnerabilities, including two with a CVSS score of 10.0: CVE-2026-83711 (Azure AD B2C elevation of privilege) and CVE-2026-70352 (Azure AI Language Authoring missing authentication). Additionally, CVE-2026-83941 (Entra ID elevation of privilege, rated 9.9) and CVE-2026-80098 (Copilot Studio cryptographic flaw) were noted. On September 8, the Patch Tuesday update addressed 70 CVEs, including critical issues in the on-premises stack, such as CVE-2026-83939 (Windows Secure Kernel Mode elevation of privilege). CVE-2026-69414 (ShieldBreak), an elevation of privilege vulnerability in the Defender Malware Protection Engine, was patched out-of-band on September 3 after being publicly exposed for three weeks. Microsoft is shifting its Self-Service Password Reset (SSPR) enforcement to default to passkeys as of September 7, with plans to phase out SMS and voice-based authentication by February 2027. This aims to enhance security by moving away from legacy credentials.
