Windows 11 Pro includes a suite of security features under Windows Security, which continuously protects the PC. Common security alerts include: 1. "Turn on virus protection" or "Real-time protection is off" alerts: These occur after installing or removing a third-party antivirus. To restore protection, open Windows Security, select Turn on in the Virus & threat protection section, and confirm. 2. "Threat found" or "Threat found - action needed" alerts: Indicate that Windows Defender has detected a potential threat. To manage these, open Windows Security, navigate to Virus & threat protection, click on Protection history, select Threat blocked, and use the Actions dropdown to quarantine or allow the file. 3. "Threat quarantined" or "Threat blocked" alerts: A Threat quarantined alert means a file is isolated for review, while a Threat blocked alert indicates successful removal by Defender. Investigate how the threat entered the system. 4. SmartScreen alerts: SmartScreen protects against malicious websites and downloads. If a threat is identified, a red warning page appears. Users can report the site as safe or proceed at their own risk. Blocked downloads can be managed in Edge's Downloads menu. 5. "This app has been blocked" alerts: Smart App Control prevents the installation of untrusted applications. Disabling this feature should only be done if the application is deemed safe. Settings can be found under Windows Security > App & browser control > Smart App Control settings.

Users may encounter the error message “Cannot complete the archive extraction wizard” when using the built-in Windows extractor for ZIP or RAR files, indicating limitations of this tool. Common issues include damaged archives, incompatible compression methods, long file paths, restricted extraction locations, insufficient disk space, or interruptions from security software. To address these challenges, users can: 1. Use third-party extractors like 7-Zip, WinRAR, or PeaZip for better compatibility and success rates. 2. Check if the archive is corrupted and re-download it if necessary, ensuring the download completes fully. 3. Shorten the file path by moving the archive to a simpler directory to avoid exceeding path limits. 4. Temporarily disable antivirus or real-time protection, as it may interrupt the extraction process. If problems persist, testing the archive on a different PC can help determine if the issue is with the archive or the current system. If the archive fails on another computer, it is likely corrupted or incomplete, requiring a fresh download or replacement.

Bitdefender Total Security offers real-time malware and virus detection, multi-layer ransomware protection, a limited daily data VPN, a password manager, parental controls, and webcam protection. It is compatible with Windows, Mac, Android, and iOS. Pros include excellent detection ratings, minimal system impact, and coverage for up to five devices. Cons are a VPN data cap unless upgraded, significant renewal price increases, and some advanced features being buried in menus. Surfshark Antivirus provides real-time malware scanning, webcam and microphone protection, data breach alerts, and is bundled with Surfshark VPN. It is available on Windows and Android. Pros include competitive pricing when bundled with VPN, a clean interface, and decent malware detection. Cons are fewer features compared to dedicated suites, limited iOS support, and being relatively new in the antivirus space. Norton 360 includes real-time threat detection, LifeLock identity monitoring (on higher tiers), a built-in VPN with no data cap, cloud backup, and a password manager. It supports multiple platforms. Pros are strong overall protection, dark web monitoring alerts, and no VPN data limits. Cons include a higher starting price, automatic renewal enabled by default, and being resource-heavy on older machines. Avast Free Antivirus offers real-time virus and malware protection, a Wi-Fi network scanner, a browser cleanup tool, and a basic ransomware shield. It is available on multiple platforms. Pros include core protection for free, lightweight installation, and an extensive threat database. Cons are aggressive upselling, past privacy concerns, and advanced features locked behind a subscription. Malwarebytes focuses on malware and adware detection, offering real-time protection (Premium only), a browser guard extension, and a light system footprint. It is available on multiple platforms. Pros include excellent detection of adware and a user-friendly interface. Cons are the lack of real-time protection in the free version and fewer features compared to full-suite competitors. Free antivirus software should prioritize real-time protection, coverage beyond basic viruses, a browser extension for blocking suspicious sites, and automatic updates. Free versions typically handle common threats adequately but lack advanced features and support found in paid versions. Some free tools may collect user data, raising privacy concerns. To install antivirus software on Windows 10, download it from the official website, follow setup instructions, and ensure background protection and automatic updates are enabled. Transitioning from Windows Defender is usually managed automatically by most antivirus programs. Running two real-time scanners can cause conflicts; instead, pair a primary antivirus with a secondary tool like Malwarebytes for manual scans. If a paid antivirus plan is not renewed, protection may revert to a limited mode or cease entirely. Microsoft Defender offers adequate protection but lacks additional features like a VPN or identity monitoring. Standard antivirus plans typically range from to 0 annually, with renewal prices often increasing.

A crypto miner virus, or cryptojacking malware, secretly uses a device’s CPU or GPU to mine cryptocurrency for an attacker, leading to increased electricity costs and potential hardware damage for the victim. It typically infects devices through phishing emails, pirated software, compromised websites, and malicious browser extensions. Monero is the preferred cryptocurrency for mining due to its efficiency on standard CPUs and privacy features. Signs of infection include overheating, high CPU usage, and increased electricity bills. Detection involves monitoring system performance and running antivirus scans. Prevention includes using antivirus software, keeping systems updated, and avoiding pirated software. Notable incidents include attacks on a European water utility and the Los Angeles Times website.
