New Botnet Puts Home PCs at Risk: AV-Comparatives Publishes Malware Protection Test

AV-Comparatives evaluated 20 consumer security products against 10,000 malware samples, focusing on the x47.c botnet, which emerged in October 2026 and is marketed by WraithTools. This botnet can steal sensitive information and turn infected devices into proxies for cybercriminals. Research indicates it can extract passwords, cookies, and data from AI service accounts. The U.S. Department of Justice noted the risk to freelancers and small businesses from such threats. In its September 2026 Malware Protection Test, AV-Comparatives found that 15 out of 20 products reached the highest protection tier, with six receiving the ADVANCED+ award: Bitdefender, ESET, G DATA, Kaspersky, Total Defense, and VIPRE. The testing revealed a reliance on cloud-based detection, emphasizing the need for consistent internet connectivity for optimal protection.

From searching to doing: Building a faster, more streamlined Windows Search

Search functionality is essential for navigating Windows PCs, and enhancements to the Windows Search Box were initiated in July to declutter the interface and improve user control. A new Windows Search experience powered by WinUI 3 will be available on the taskbar for Windows Insiders starting October 7, focusing on speed and efficiency with a streamlined design. The user interface has been simplified into a single list format, and improvements include better matching for typos and synonyms. Future updates will introduce inline previews, richer file details, and the ability to filter results. Inline actions will allow users to complete tasks directly from the search interface, such as toggling settings and managing their workspace. There are plans to integrate the new search experience into the Start menu and enhance its capabilities further. The new search experience is rolling out to Windows Insiders in the Experimental channel, with English as the initial supported language. Feedback can be shared through the Feedback Hub.

Your Windows PC can now reach other PCs through Windows App

Microsoft has launched a significant enhancement to its Windows App, now allowing general availability for remote PC connections on Windows. Users can access both physical and virtual Windows PCs, integrating resources from Windows 365, Azure Virtual Desktop, and Microsoft Dev Box into a single interface. The Windows App replaces the previous Remote Desktop app from the Microsoft Store and the standalone Remote Desktop client, while the traditional Remote Desktop Connection tool (mstsc.exe) remains supported. Users can connect to remote PCs by entering the computer's name or IP address, with options for display preferences and local resource redirection. All redirections are turned off by default for security, and connections can be saved and pinned to a Favorites list. Marvin Quinzon, Senior Program Manager at Microsoft, highlighted the importance of this update for users and organizations needing flexibility in cloud and traditional remote access scenarios.

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.
