Microsoft Warns of GigaWiper Backdoor Built to Destroy Windows PCs

Microsoft has unveiled a destructive Windows backdoor named GigaWiper, which allows operators remote control over compromised systems to execute irreversible damage. GigaWiper originated from cyberattacks in October 2025 and is a composite of code from at least three malware families. It maintains its presence through a scheduled task disguised as “OneDrive Update,” executing at startup and every minute. GigaWiper can obliterate partition information, overwrite physical drives, and restart systems. It also mimics ransomware by encrypting files with the .candy extension, using randomly generated keys that are not stored, making recovery impossible. The malware has connections to the Crucio ransomware and resembles FlockWiper, with rewritten code in Go. GigaWiper features 20 command codes for various functions, including executing PowerShell instructions, managing processes, capturing screenshots, and remote access similar to VNC. It can remain on a system for surveillance until its destructive functions are activated. Microsoft Defender includes detection capabilities for GigaWiper, and users are advised to enable tamper protection and monitor for suspicious activities.

How We Test Antivirus and Security Software

Most software applications clearly indicate their functionality, but the effectiveness of antivirus utilities is often less tangible. PCMag rigorously evaluates antivirus products through comprehensive tests that validate their claims, including real-world malware samples and various protective measures. Each antivirus tool is assessed based on its on-demand scanner and real-time monitor capabilities. PCMag compiles fresh malware samples annually, analyzing them to ensure they are suitable for testing. The testing process includes evaluating malware-blocking capabilities and web-level protection against known malware-hosting sites. Phishing site detection is also tested using recent URLs, and antispam testing has been simplified due to the effectiveness of email providers. Performance impact tests have been discontinued as modern security suites show improved efficiency. Firewall protection is evaluated through program control, exploit defenses, and overall resilience against malware. Parental control features are tested for effectiveness in content filtering and monitoring. Ransomware protection is assessed by releasing real-world samples in a controlled environment. PCMag monitors independent antivirus lab tests from various organizations, including AV-Test, AV-Comparatives, SE Labs, MRG-Effitas, and AVLab, to inform their reviews. An aggregate testing score is calculated to summarize lab results. Testing methodologies do not include VPN evaluations, which are covered separately.

Why I Use Additional Antivirus Protection on Top of Microsoft Defender

Microsoft Defender has evolved into a reliable security tool, integrating seamlessly with the Windows operating system and offering features such as real-time malware scanning, cloud-based threat intelligence, collaboration with the Windows firewall, and ransomware protections. It receives automatic updates through Windows Update, providing users with up-to-date threat definitions. While Defender is sufficient for users with straightforward online activities, those engaging in riskier behaviors or handling sensitive information may benefit from additional protection. Some antivirus solutions offer features that Defender lacks, such as enhanced web protections, phishing defenses, and parental controls. The text mentions that the author uses Bitdefender alongside Microsoft Defender for added security, citing its stronger web protections and broader range of tools. It emphasizes that effective security also relies on user habits, including keeping software updated, avoiding suspicious downloads, using strong passwords, and regularly backing up data.

How to Install McAfee Antivirus on Windows 11 or 10

Installing third-party antivirus software like McAfee on Windows 11 can be challenging due to the built-in Windows Security, which can complicate the installation process. Users may face issues such as silent failures from conflicting software, permission problems on restricted machines, or restrictions due to S Mode on new laptops. Windows 11 includes Windows Security, which is effective for malware protection, but McAfee may be necessary for compliance, additional features, or centralized protection for multiple devices. McAfee supports Windows 11 Home, Pro, and Education editions but not Enterprise. The minimum hardware requirements include a processor of 1 GHz or faster, at least 2 GB of RAM (4 GB recommended), 1.3 GB of free disk space, an internet connection for download and updates, and a display resolution of at least 1024×768. McAfee requires a persistent internet connection for activation and updates. Before installing McAfee, users should check if their device is in S Mode, as McAfee cannot be installed in this mode. They must remove any existing antivirus software completely, as leftover files can interfere with the installation. Users should also ensure that Windows 11 is up to date and verify that there is enough disk space available. To download McAfee, users should go directly to the McAfee trial page to avoid scams. After downloading, they need to run the installer and restart their computer after installation. Users should then activate McAfee, run a manual update, and conduct a full system scan. Common installation problems include freezes during download, errors due to S Mode, and issues with Windows Security not recognizing McAfee as the active antivirus. Users can verify that McAfee is functioning correctly by checking the system tray icon, Windows Security settings, and the McAfee dashboard. To uninstall McAfee, users should go to Settings > Apps > Installed Apps, select McAfee, and follow the prompts to remove it. After uninstallation, Windows Security will reactivate automatically. McAfee offers several plans for Windows users, including Basic, Essential, Premium, and Advanced, each with different features and device limits. The Basic plan is suitable for single-device users without additional needs, while families may benefit from the Essential or Premium plans.

Bitdefender vs McAfee

Bitdefender and McAfee are both established antivirus solutions that achieve similar lab test scores, often earning 18 points in assessments by AV-Test and AV-Comparatives. Bitdefender offers a more economical pricing structure, with its Antivirus Plus plan priced between .99 and .99 per year for three devices, while McAfee's plans start at .99 for one device. In real-world malware protection tests, Bitdefender achieved a 99.8% protection rate, compared to McAfee's 99.3%. McAfee includes firewall protection at the antivirus level, while Bitdefender reserves its firewall for higher-tier plans but offers better exploit protection. Bitdefender successfully thwarted 11 out of 12 ransomware attacks in controlled tests, while McAfee's ransomware protection is less reliable. Both offer limited VPN services, with Bitdefender providing 200MB per day and McAfee offering between 250MB and 500MB per month. McAfee completes scans more quickly but uses more CPU, while Bitdefender is more thorough. Bitdefender includes additional security features like anti-tracker and secure browser, whereas McAfee's features are more limited.
