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.

Intego Mac Internet Security

PCs were introduced before Apple’s Macintosh, leading to the emergence of PC viruses and the establishment of antivirus companies, with Macintosh protection being less prioritized. Intego focused on Macintosh security from the start, offering Intego Mac Internet Security, which includes a firewall that manages network permissions and defends against external attacks. Intego has been effective against Mac malware, achieving a 99.1% malware detection score in independent lab tests, although it lacks phishing protection, a feature offered by competitors Norton 360 Deluxe and Bitdefender Antivirus Plus. Intego's pricing is competitive, with a standard annual fee of .99 for a single license and .99 for three licenses. A five-device subscription costs .99, while the Mac Premium Bundle starts at .99 annually and includes additional features. A 14-day free trial is available, and free alternatives like Avast and AVG are also on the market. Intego supports older macOS versions back to Mavericks (10.9), but the latest version requires High Sierra (10.13) or later. The installation process for Intego is straightforward, requiring a restart and granting necessary permissions. The main interface includes components for updates, firewall, and antivirus, with user-friendly access to scanning options. Intego has received certification from AV-Comparatives and detected 100% of Windows malware samples in tests. Its quick scan takes about two and a half minutes, while a full system scan takes seven minutes. Intego's Safe Browsing feature checks existing browser protections but lacks a dedicated antiphishing solution. The NetBarrier firewall allows users to classify their network and manage traffic permissions effectively, although it may be complex for some users.

How to disable the PC webcam and protect it from unauthorized access

The webcam is a crucial tool for remote communication but poses privacy risks, particularly through a threat known as CamFecting, where unauthorized access can occur via malware, malicious websites, or system vulnerabilities. Preventive measures include using antivirus software, disabling the webcam when not in use, and physically covering the camera with privacy caps or tape. Signs of unauthorized access include unexpected illumination of the webcam light, unusual camera behavior, unknown files on the system, abnormal data consumption, and decreased battery life. To deactivate the webcam, users can adjust settings in major browsers and operating systems. Maintaining digital hygiene, such as regularly updating software, using security systems like firewalls and VPNs, and being cautious of phishing attempts, is essential to minimize risks.

5 reasons I regret not deploying my own home firewall sooner

A hardware firewall enhances network security by monitoring and filtering all traffic, preventing unauthorized access based on pre-defined rules, and analyzing traffic patterns for anomalies. It employs Next-Generation Firewall technology for deep packet inspection, utilizes GeoIP restrictions, and runs Intrusion Prevention/Detection Systems (IPS/IDS). Implementing a Zero Trust architecture minimizes device access, and notifications alert users to new device connections. Segregating IoT devices onto a dedicated VLAN reduces security risks. A multi-layered security approach, including rules-based and deep packet inspection, is essential for comprehensive protection. Hardware firewalls often run on Linux or FreeBSD, allowing additional functionalities like ad blocking through services such as Pi-hole. Cataloging devices improves troubleshooting and network management. The adoption of hardware firewalls is increasingly necessary due to the rise of connected devices in homes.

Windows Server 2025 may lose DC connectivity after restart

Microsoft has warned about potential accessibility issues with Windows Server 2025 domain controllers after a restart, where affected servers revert to the default firewall profile, disrupting applications and services. A temporary workaround involves manually restarting the network adapter on the impacted servers using the PowerShell command: Restart-NetAdapter *. This workaround needs to be reapplied after each restart of the domain controller, and Microsoft recommends setting up a scheduled task to automate this process. Windows Server 2025, launched earlier this year, introduced new features and security enhancements but has faced previous issues, including freezing Remote Desktop sessions and accidental upgrades from Windows Server 2022. Developers are currently working on a permanent solution for the domain controller issue.

Windows Server 2025 Restart Bug Breaks Connection with Active Directory Domain Controller

Microsoft has warned IT administrators about a significant issue affecting Windows Server 2025 domain controllers, which may struggle to manage network traffic after a system restart. This problem arises because the domain controllers revert to the standard firewall profile instead of the required domain firewall profile, leading to potential inaccessibility on the domain network, application failures, and open ports that could pose security risks. The issue specifically affects Windows Server 2025 systems with the Active Directory Domain Services role, while client systems and earlier server versions remain unaffected. To address this, Microsoft recommends a temporary workaround: manually restarting the network adapter using PowerShell with the command Restart-NetAdapter * after each reboot. Administrators are advised to create a scheduled task for automation, monitor domain controllers for disruptions, and minimize unnecessary restarts. Microsoft is working on a permanent fix, with an update expected in the future.
