Malwarebytes is Windows antivirus and anti-malware software for finding and removing threats, with free scanning tools and paid real-time protection against malicious files, ransomware, exploits, and dangerous websites.
Malwarebytes is Windows security software that detects and removes malware, viruses, and unwanted programs, with paid protection layers designed to stop threats during everyday use. The application suits people investigating a suspicious download, checking a computer after unusual behavior, or maintaining ongoing protection through a subscription. Users start a scan, review its findings, and decide how to handle detected items through the results and quarantine controls. Free scanning provides an entry point for checking existing files, while paid features extend protection beyond scans that users launch themselves. The desktop interface brings scanning, detection history, and protection settings into one place for routine security tasks.
Malwarebytes works at the device level, so its scan settings and active protection should be configured around the computer’s workload. Cloudflare One Client addresses managed network connectivity, making it a useful comparison when distinguishing endpoint malware removal from organization-controlled traffic filtering. Windows users can inspect selected folders or external drives rather than repeatedly checking unrelated data. Custom scans offer deeper options, including rootkit detection on supported hardware, but additional checks can increase scanning time. Current documentation supports Windows 10 and Windows 11 with S mode disabled. Internet access remains necessary for activation and updates, including fresh component and threat-detection databases.
Malwarebytes helps users turn a suspected infection into a manageable review process instead of guessing which files to delete. Scan findings provide a concrete starting point, and quarantine gives users time to examine a detection before making a permanent removal decision. That distinction matters when a legitimate application is mistakenly flagged or a computer contains files needed for work. Targeted scanning can also save effort when the concern is limited to a download folder or removable drive. People who choose paid protection can reduce their reliance on remembering to launch manual checks, while the free tools remain useful for investigating existing files. Keeping scan history available helps users see what was found and what action followed, which is useful when discussing a problem with support. These controls support a more repeatable cleanup workflow, although removing detected malware does not by itself restore damaged documents or reverse every change an infection made.
Key capabilities and highlights.
Malwarebytes lets users initiate scans to look for malware and other detected threats already present on a computer. Free Quick and Custom scans support checks without a paid protection subscription. Results identify detections for review, making scanning useful when investigating suspicious behavior or checking files after an unexpected download.
Paid real-time protection monitors for threats while the computer is in use, reducing reliance on scans started after a problem appears. Windows protection includes malware, ransomware, and exploit layers. Malwarebytes exposes protection controls in the application so users can check which layers are active and recognize when a protection component is disabled.
Web Protection helps block connections to dangerous online destinations as part of the paid protection features. This adds a network-facing layer to local file scanning and can interrupt contact with harmful sites. Users can review its status in protection settings; installing the free scanner alone does not enable this paid capability.
Quarantine keeps detected items separate while users decide whether they should be removed permanently or restored. Malwarebytes provides these controls through Detection History, including an option to exclude a restored trusted item from future detections. Permanent deletion removes the quarantined copy, so reviewing uncertain detections before deleting them preserves recovery options.
Custom scans can inspect for rootkits that hide on a device and interfere with normal system operation. In version 5.6.5, rootkit scanning is restricted to Custom scans and is unavailable on ARM devices. Enabling the option adds a deeper check but can increase scan time compared with less extensive scanning.
Scan settings let users choose how potentially unwanted programs and potentially unwanted modifications are handled. Available actions include ignoring detections, displaying a warning, or treating them as malware. Malwarebytes therefore allows a more deliberate response to borderline software and configuration changes instead of forcing every detection into the same handling rule.
Windows users can start a scan directly from File Explorer by right-clicking a file, folder, or external drive. This shortens the workflow for checking a specific downloaded item or removable storage device. After scanning finishes, the application provides the report and controls for quarantining detected threats without requiring a broader scan.
The application retains reports from previous scans so users can review detection results after the initial summary closes. Malwarebytes makes this history accessible through its reporting interface, helping users track what a scan found and revisit the outcome. Reports also provide a useful reference when explaining a recurring concern to technical support.

Common questions about Malwarebytes.
Yes. Quick and Custom scans are available free, while real-time malware, web, ransomware, and exploit protection require a paid subscription. The Windows app’s free and paid capabilities differ, so a completed free scan does not mean continuous protection is active.
Current requirements list Windows 10 and Windows 11, at least 4 GB RAM, and 1 GB of free installation space. Windows S mode must be disabled. An internet connection is required for installation, activation, and updates.
Yes, through Custom scans on supported Windows hardware. Version 5.6.5 restricts rootkit scanning to that scan type, and the option is not available on ARM devices. Enabling it can make the scan take longer.
Released August 20, 2026, this update improves subscription details, limits spotlight recommendations to one per day, and fixes repeated opening and closing of the app. It also improves quarantine deletion messaging and fixes a missing Report button in Scam Guard.
Yes. Open Detection History, select the item under Quarantined items, and choose Restore if you have established that it is trustworthy. A quarantined item that you permanently delete through the app can no longer be restored from quarantine.
