Switch Antivirus Software: 13 Steps, Zero Gaps [2026]

ESET rebranded its home security lineup in 2026, introducing ESET HOME Security Essential and Premium, and added automatic ransomware backup to its Ultimate plan. The NOD32 engine was updated to version 19.2 on August 27, 2026. IPVanish launched a next-generation antivirus product on October 7, 2026, built on the VIPRE engine and integrated into its VPN application. Many Australians are reconsidering their antivirus options due to discrepancies between current product names and older installations. A comprehensive 13-step guide has been developed to facilitate the transition to new antivirus software, addressing potential risks such as performance issues from running multiple engines, improper uninstallation, and loss of license keys. In 2026, ESET introduced features like a Website Security Inspector and a Microphone Monitor, while IPVanish's antivirus includes real-time anti-ransomware protection and machine-learning threat detection. Security.org's 2025 report indicated that 84% of users made no changes to their antivirus software over the past year, with many only reconsidering when faced with price increases or product discontinuations. The choice between paid and free antivirus solutions is significant, with 54% of third-party users paying for their software. ESET's Ultimate tier is the only one that includes ransomware backup features. Before switching antivirus products, users should ensure they are running compatible operating systems, have administrator access, document current and new antivirus version numbers, and have a stable internet connection. A PowerShell command can check the current antivirus status. Steps for migration include auditing current antivirus features, choosing a suitable replacement, exporting license keys, and using official removal tools to uninstall the old software. After installation, users should verify real-time protection is active and rebuild exclusions and scan schedules. Common pitfalls during migration include failing to uninstall the old antivirus completely, forgetting to disable tamper protection, and losing exclusion lists. For mobile devices, permissions from the old antivirus must be cleared to avoid conflicts. Advanced users managing multiple devices may benefit from staggering migrations and checking for known vulnerabilities in the antivirus products. A PowerShell script can be created to log the antivirus state before and after migration.

Is paid antivirus actually a waste of money for your PC in 2026?

Windows has evolved from being a target for malware to having robust built-in protection, particularly through Microsoft Defender Antivirus, which has improved from a score of 0.5 in 2015 to a perfect score of six in 2026, detecting 100% of threats. Microsoft Defender operates seamlessly in the background, automatically scanning files and applications. Third-party antivirus solutions, while offering additional features like anti-scam tools and VPNs, may not be necessary for all users, especially since many browsers have built-in protections. Users are encouraged to reassess the necessity of paid antivirus subscriptions, as free versions can be intrusive and may lead to conflicts with Defender. Performance tests indicate that third-party antivirus solutions can impact game performance, with Malwarebytes Premium showing a notable reduction in frame rates during scans. For most users, Windows' built-in protection is likely sufficient unless specific additional features are needed.

Microsoft: October Windows Server updates break Exchange sign-in, mail flow

Microsoft has acknowledged that the latest Windows Server security updates are causing sign-in and mail delivery issues for certain Exchange Server systems, particularly affecting users of Windows Server 2019 and beyond. Affected customers report encountering a "MapiExceptionMdbOffline" error and Event ID 1006 in application logs. The October 2026 Windows security update has introduced a default limit on memory allocated to Endpoint Mapper, which may be insufficient under heavy load for Exchange Server workloads. Microsoft clarified that the reported issues are not related to the October 2026 Exchange server security updates and advised against uninstalling them. A temporary workaround involves modifying a registry key to increase the Endpoint Mapper memory limit. Additionally, Microsoft announced it would cease shipping extended security updates for Exchange 2016 and 2019 this month.

I needed to see the new Windows 11 Photos app in action to fathom how fast it is — it’s like switching from dial-up to broadband

Microsoft's Photos app is undergoing a significant transformation, introducing a revamped Gallery, Editor, and Viewer. The new Editor is built using WinUI 3, enhancing usability and performance. It features advanced editing capabilities, including Relight, which allows users to add up to three light sources to photos.

ReactOS reaches major milestone with NTFS install support

ReactOS has integrated the ability to install directly onto an NT File System (NTFS) drive partition, marking a significant advancement as it moves closer to its beta release. Previously, users had to maintain a FAT32 partition for installations. The ReactOS team aims for binary compatibility with Windows Server 2003, making NTFS support a crucial milestone. However, the new driver currently lacks essential features like caching, journaling, and robust security support, which could affect performance and security. Users are advised to be cautious and aware of potential bugs as they explore this new functionality.

Why Windows 11 still won’t let you name a file CON, and Microsoft’s explanation goes back to MS-DOS

In Windows 11, certain names such as CON, PRN, AUX, and NUL are reserved as they correspond to specific devices, preventing users from naming folders with these terms. These reserved names date back to DOS 1.0, where folders did not exist. The names have specific functions: CON refers to the console, PRN to the printer, AUX to an auxiliary device, and NUL to a null device that discards output. Attempts to rename a folder to any of these names result in an error message indicating the device name is invalid. Adding extensions to these names does not bypass the restriction, as names like NUL.txt are still treated as equivalent to NUL. Despite some changes in Windows 11, the prohibition against using these reserved names for files or folders remains in place due to legacy compatibility concerns.

Latest Windows Updates Introduce Exchange Server Issues

Organizations using on-premises Microsoft Exchange Server are experiencing stability issues after the October 2026 Windows Server updates, which Microsoft has confirmed can lead to unreliable Exchange services, especially in environments with heavier workloads. Administrators have reported problems such as connectivity failures with Outlook on the web, disruptions in mail flow, and complications with database availability groups (DAG), all emerging post-update. This bug affects Exchange Servers on Windows Server versions 2016, 2019, 2022, and 2025. Microsoft has identified that the issue is related to limitations in Endpoint Mapper requests and has recommended a registry-based mitigation to improve capacity and reduce service degradation. The default limit of 512 simultaneous Endpoint Lookup calls may be insufficient under heavy load. Microsoft is investigating the issue and will provide further information. Organizations are advised to maintain critical security updates while implementing additional mitigation measures and closely monitoring affected systems until a long-term solution is found.
