5 Free Antivirus Programs To Eliminate Malware and Viruses (2025)

Users are increasingly seeking effective malware protection without the cost of premium software, leading to the emergence of free antivirus programs that offer robust security features. This trend is particularly beneficial for Windows 11 users who want real-time protection while staying within budget. Several leading cybersecurity firms provide free antivirus solutions equipped with advanced features such as real-time scanning, phishing defenses, cloud-based malware detection, and system optimization tools. These free programs can adequately protect a diverse audience, including gamers, remote workers, students, and casual users. Top free antivirus programs for Windows 11 in 2025 include: 1. Bitdefender Antivirus Free: Utilizes the same malware engine as its paid version, offers real-time detection, anti-phishing protection, and is ultra-light on system resources. 2. Microsoft Defender Antivirus: Integrated into Windows 11, provides cloud-delivered protection and built-in ransomware mitigation without ads. 3. Avast Free Antivirus: Offers additional tools like network scanning and a Do Not Disturb mode for gaming. 4. AVG AntiVirus Free: Features a simpler interface, link and attachment protection, and fewer pop-ups. 5. TotalAV Free Antivirus: A newer option with a clean interface, real-time protection, and a junk file cleaner. Key factors to consider when selecting free antivirus software include real-time protection, low resource usage, minimal intrusion, and extra security tools. While free solutions are suitable for most users, premium protection may be necessary for small businesses or those handling sensitive data. For gamers, Bitdefender and Avast are recommended for their low system impact and gaming modes. For remote workers, Microsoft Defender and TotalAV are highlighted for their ease of use and integrated protections. Essential features of effective antivirus programs include robust virus protection, real-time scanning, and a behavior shield to detect new threats. Performance should not significantly slow down the system, and the interface should be user-friendly. Experts recommend Windows Defender for basic protection, with AVG and Avast receiving endorsements for their feature balance, while Bitdefender Free is noted for its detection rates and minimal system impact. Free antivirus programs may lack advanced features and technical support compared to paid versions.

Microsoft Recall finally launches for AI PC users, along with some other new features, almost one year after Copilot+ was announced

Microsoft has reintroduced its Recall feature, initially designed for Qualcomm Snapdragon X-powered laptops, which captures snapshots of users' desktops to help locate old documents, images, and web pages. Enhanced security measures have been implemented, including Windows Hello sign-in, data encryption, and isolation protocols, with all data processed locally on users' devices. Recall is an opt-in feature that can be removed. Additionally, Microsoft has introduced an AI-powered Windows search mechanism that allows users to search for files by description. These features are currently exclusive to devices with Qualcomm Snapdragon X processors, with support for AMD Ryzen AI 300 series and Intel Core Ultra 200V series chips expected later this year. Users without compatible hardware must rely on traditional file management methods.

Why aren’t there antivirus apps for the iPhone?

In recent years, the belief that iOS devices are "immune" to viruses has been challenged as cybercriminals increasingly target these platforms. Apple’s security measures, including sandboxing, help isolate apps to prevent the spread of malware. The App Store is strictly controlled, with Apple reviewing apps for security compliance, resulting in few harmful applications being reported. Antivirus software available in the App Store, from companies like McAfee and Norton, operates under the same constraints as other apps and cannot directly access the operating system kernel. Users are advised to avoid jailbreaking their devices, enable automatic updates, and take precautions such as avoiding public charging stations and regularly reviewing app permissions. Utilizing a password manager or VPN can enhance security, and those who have experienced data breaches may consider identity theft protection.

5 reasons I use Windows 11 Backup over Macrium Reflect

Backups are crucial for data preservation, especially when primary machines face issues. Windows 11 provides various backup tools, including the Windows Backup app, which allows users to safeguard files, applications, and system preferences. This app can restore backups during Windows reinstallation and remembers wireless network credentials, simplifying the restoration process. It enables users to restore Microsoft Store apps with a single click and features a user-friendly interface that makes navigation easy. Windows Backup also offers data protection against ransomware through OneDrive storage. However, it cannot restore third-party apps and has limited cloud storage of 5GB on OneDrive, necessitating careful management of saved files.

Microsoft’s Free Upgrade Offer—Bad News For 240 Million Windows Users

Microsoft is encouraging approximately 240 million PC owners to recycle outdated devices, as they will not qualify for a free upgrade to Windows 11 without new hardware. The company emphasizes the importance of the Trusted Platform Module (TPM) 2.0, a security chip that determines eligibility for the upgrade and protects sensitive data. TPM 2.0 offers several security benefits, including data encryption, verification of trusted software, detection of physical tampering, and support for advanced security features in Windows 11. Currently, around 240 million PCs are estimated to be ineligible for the upgrade, which may hinder the adoption of Windows 11 and leave many devices vulnerable to cyber threats.
