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.

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.

His scanner wouldn’t work on Linux — so he let Claude study the Windows driver

Christian Schaller, an engineering director at Red Hat, faced challenges digitizing family negatives with a Plustek OpticFilm 8200i scanner due to Linux driver incompatibility. After pausing the project, he successfully scanned using a new strategy and launched an open-source initiative called hw-harness to help developers tackle hardware lacking Linux support. Schaller reverse-engineered the scanner driver by analyzing USB traffic and comparing it with data from a Windows environment. His driver outperformed the upstream version in speed and included features like infrared dust removal and various scanning capabilities. He also developed an application named Negative Vibes for image processing. Additionally, Schaller improved the camera on his Lenovo ThinkPad X1 Carbon by addressing issues in the Linux kernel and libcamera, resulting in significant enhancements in image brightness and color accuracy. His hw-harness project is available on GitHub, providing tools for driver development and analysis.

Tiny11 puts Windows 11 on a diet without the PowerShell workout

Tiny11 Builder has released a new desktop application preview for creating lightweight Windows 11 installation images, minimizing the need for PowerShell knowledge. The tool generates an ISO image by removing bundled applications and selected system components, supporting Windows 11 installation media from version 22H2 onward, including 26H2. It features a WinUI 3 desktop application with a new C# image builder, offering three build modes: Tiny11, Tiny11 Core, and Custom. The ISOs produced are not supported by Microsoft, and users are cautioned that Tiny11 Core should be used only in test virtual machines. There is no guarantee that the tool will bypass Windows 11's hardware and account requirements. A license is still required for the modified installation, as it remains Microsoft Windows 11.

Windows 11 promises to clean up bloat, but disabling its own features is the only thing that works

Upon installing Windows 11, users encounter numerous pre-installed applications, promotional tiles, and cloud-connected features. These apps are organized in two phases: system-level staging and user-specific activation. The AppX Deployment Service registers these apps for users, creating app data folders. Microsoft also embeds custom app shortcuts and trial software into the Start menu using LayoutModification.json. During setup, Microsoft's Consumer Experience feature connects to cloud servers, downloading app placeholders that are pinned to the Start menu. Local search is integrated with Bing by default, sending requests for suggestions and promoted content. To clean up Windows 11, users can uninstall non-essential applications through Settings, but this only removes them from the user profile. To permanently eliminate app templates, PowerShell commands can be used. Users can disable promotional content in Settings under Personalization and Privacy & Security. To sever Bing integration from search, modifications in the registry editor are required. The Task Manager can help manage startup applications, allowing users to disable non-essential third-party apps. While removing unnecessary components can improve performance, essential packages like Edge WebView2 runtime, Microsoft Defender, and the Microsoft Store should be retained to avoid system errors. Regular maintenance is necessary, as Windows updates may reinstall previously removed apps.

Why Antivirus Flags Game Tools and How to Verify Downloads Safely

In gaming, tools such as utilities, beta applications, and modding tools are often distributed as APK, IPA, or desktop files, and it is essential to investigate their origin, version, and any security warnings before installation. Antivirus software flags potential threats based on known malicious signatures, behavior patterns, and reputation data. Tools that modify game clients may receive heightened scrutiny, and classifications like “HackTool” or “Riskware” do not definitively indicate a file's functionality. Identical game utilities can exist on various platforms, and a familiar website does not guarantee authenticity. It is crucial to verify the publisher, update date, version, and installation method of a file. The SHA-256 hash verifies file integrity but does not ensure safety from malware. Calculating a file hash can be done using specific commands in Windows, macOS, or Linux. Multi-engine scanning platforms like VirusTotal provide insights, but a lack of detections does not guarantee safety. Even if a file matches its reference hash and raises no alerts, it may still violate online game terms. A pre-installation checklist includes confirming the publisher, checking file types, comparing SHA-256 hashes, reviewing security findings, keeping antivirus protection enabled, and consulting platform rules. A cautious approach integrates source verification, file integrity checks, security assessments, and compliance with platform regulations.

How to supercharge your Windows 11 PC with this built-in automation tool

Windows 11 includes a Task Scheduler that automates repetitive tasks to enhance productivity. To set up a task, users should open Task Scheduler, select "Create Task," and fill in details under General, Triggers, Actions, Conditions, and Settings. It's important for laptop users to avoid scheduling tasks that run every five minutes to maintain low-power idle states. The "Run with highest privileges" option should be used cautiously for security reasons. Three recommended automations include: 1. Using WinGet to keep software updated with the command winget upgrade --all --silent --accept-package-agreements --accept-source-agreements --disable-interactivity, scheduled weekly. 2. Disabling unnecessary startup applications and launching them with a delayed logon trigger to reduce startup clutter. 3. Automating tasks with PowerShell for file transfers or system maintenance, ensuring they run during idle times or when connected to AC power. Windows also performs some maintenance tasks automatically, such as deleting temporary files and optimizing drives.

Microsoft warns fake CAPTCHA tests are hijacking Windows PCs

Microsoft has warned Windows users about a cyber threat that disguises itself as a CAPTCHA test, where cybercriminals use fraudulent verification pages to trick users into executing commands that can install malware. This tactic involves users being directed to a compromised website that presents a fake verification window, prompting them to copy text and execute it in the Windows Run dialog. This method allows attackers to bypass antivirus software by pre-loading malicious scripts disguised as harmless images in the browser's cache. Once activated, the malware collects system information, steals data, and maintains long-term control over the system. Microsoft recommends using robust security software and being aware that no legitimate service will ask users to copy and paste commands into system dialogs.
