Best Antivirus Software for Windows PCs in 2026

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.

MiningDropper Android Malware Exploits Lumolight App

Researchers at Cyble Research and Intelligence Labs (CRIL) have discovered an Android malware framework called MiningDropper, which is being used in various campaigns to distribute malicious payloads such as cryptocurrency miners, infostealers, Remote Access Trojans (RATs), and banking malware. Over 1,500 MiningDropper samples were detected in one month, with many showing minimal antivirus detection. MiningDropper operates as a multi-stage delivery framework that employs techniques like XOR-based obfuscation and AES encryption to evade detection. A recent variant uses a trojanized version of the Lumolight application as the initial infection vector, often spread through phishing links and fraudulent websites. The malware executes a series of stages, starting with decrypting an embedded asset and loading additional payloads, including a counterfeit Google Play update interface to deceive users. Two main campaign clusters have been identified: an infostealer campaign targeting Indian users by impersonating trusted entities, and a global campaign distributing the BTMOB RAT, which enables credential theft and device takeover. The final payload capabilities include extracting sensitive data, enabling full device compromise, facilitating financial fraud, and unauthorized cryptocurrency mining. MiningDropper's modularity allows it to adapt and scale across various campaigns while maintaining low detection rates.

Windows Update Warning: Fake Windows 11 24H2 Site Pushes Password-Stealing Malware

A sophisticated fake Windows update site has emerged, designed to mimic Microsoft’s branding to distribute malware, specifically targeting individuals seeking early access to Windows 11 version 24H2. The fraudulent site resembles a legitimate cumulative update download page, using familiar design elements to evade detection. The malware operates as an information-stealing entity, targeting saved passwords and browser sessions, potentially bypassing two-factor authentication. It transmits stolen credentials through encrypted channels to external servers. The installer uses legitimate packaging tools to minimize detection and employs obfuscated scripts within legitimate software components. The campaign modifies system startup entries and creates disguised shortcuts to maintain persistence. Researchers noted the use of a typosquatted domain and meticulously spoofed file properties. As of April 2026, Microsoft has not released Windows 11 version 24H2 to the public, and legitimate updates are only available through Windows Update. Users are advised to obtain updates exclusively through official channels and keep security features updated.

Fake Windows 11 24H2 Update Site Distributes Password-Stealing Malware

A recent discovery by Malwarebytes has identified a cyber threat involving a typosquatted domain that mimics official Microsoft support pages. This site uses authentic branding and KB-style reference numbers to deceive users into downloading what appears to be a legitimate cumulative update. The malware, once installed, operates stealthily, stealing passwords from browsers and active sessions, which allows attackers to bypass two-factor authentication. The stolen data is sent to external servers through encrypted channels. Initial scans showed zero detections by multiple antivirus engines due to the malware's obfuscated scripts. It also modifies system startup entries and creates disguised shortcuts for persistence. Microsoft has not yet released Windows 11 version 24H2 to general users, and updates should only be obtained through official channels to avoid potential threats.

This fake Windows 11 24H2 update looks perfect, until it avoids antivirus and steals your passwords

Cybercriminals are using sophisticated tactics to deceive users, particularly with a counterfeit website posing as a legitimate Windows 11 update. This site operates under the domain microsoft-update[.]support and is designed to trick individuals into downloading malware that compromises sensitive information. The site is written in French and mimics a genuine cumulative update for Windows 11, version 24H2, featuring a convincing KB article number and a blue download button. The malware is packaged as a Windows update using the WiX Toolset 4.0.0.5512 and is labeled "WindowsUpdate 1.0.0.msi," with properties that suggest it is from Microsoft. At the time of analysis, VirusTotal showed no detections for the malware, which conceals its harmful code within an Electron shell, making it difficult to identify. Users are advised to download updates directly through the Windows Settings app or from Microsoft's official support hub.

Stealthy Malware Campaign Uses Fake Windows Update Site To Infect PCs

A new malware campaign targets Windows users by using a fraudulent clone of a Microsoft website to steal sensitive information. Victims are directed to a typo-squatted web address that resembles an official site, where they are prompted to download a file named WindowsUpdate 1.0.0.msi. This file uses a legitimate open-source installer framework and incorporates Electron, JavaScript, and Python, making it difficult to detect; VirusTotal showed zero detections across 69 engines. The malware maintains persistence by modifying the Windows registry and placing a shortcut named Spotify.lnk in the startup folder. Currently, the campaign primarily targets French-speaking users, but similar tactics may spread to other regions. Users are advised to apply updates only through the Windows Update feature in the Settings menu.

Fake Windows 11 support site offers ‘update’ that steals data and evades antiviruses

Malwarebytes has discovered a counterfeit Windows support site offering a fake "cumulative update" for Windows 11 24H2. Users who click the "Download Update" button download an 83MB package designed to compromise sensitive information, including passwords and payment details. The file, named WindowsUpdate 1.0.0.msi, falsely lists Microsoft as the author and is created using WiX Toolset 4.0.0.5512. VirusTotal reported zero detections for the main executable and VBS launcher, highlighting the malware's architecture designed to evade detection. The malicious website's address includes "microsoft-update.support," differing from the legitimate support site. Malwarebytes has added the malicious site to its detection service database.

Fake Claude site installs malware that gives attackers access to your computer

Claude, an AI tool developed by Anthropic, receives nearly 290 million web visits monthly and has become a target for cybercriminals. A fake website has been found that impersonates Claude, distributing a trojanized installer named Claude-Pro-windows-x64.zip. This installer, while appearing legitimate, deploys PlugX malware, granting attackers remote access to users' systems. The fraudulent site mimics the official download page and uses passive DNS records linked to commercial bulk-email platforms, indicating active maintenance by the operators. The ZIP file contains an MSI installer that incorrectly spells "Claude" as "Cluade" and creates a desktop shortcut that launches a VBScript dropper. This script runs the legitimate claude.exe while executing malicious activities in the background, including copying files to the Windows Startup folder to ensure persistence after reboot. The attack utilizes a DLL sideloading technique recognized by MITRE as T1574.002, where a legitimate G DATA antivirus updater is exploited with a malicious DLL. Within 22 seconds of execution, the malware establishes a connection to an IP address associated with Alibaba Cloud, indicating control over the compromised system. The dropper script also employs anti-forensic measures to delete itself and the VBScript after deployment. Indicators of compromise include the filenames Claude-Pro-windows-x64.zip, NOVUpdate.exe, avk.dll, and NOVUpdate.exe.dat, along with the network indicator 8.217.190.58:443 (TCP) as the command and control destination. Users are advised to download Claude only from the official site and to remain vigilant against potential compromises.
