Top Malware Removal Tools Put to the Test on Infected Systems
According to Gizmodo’s 2026 test of malware removal tools, six products removed every infection placed on a deliberately infected PC.

The meaningful differences were scan time, detection depth, false alarms, and whether the tool provides protection after cleanup. For most users, Malwarebytes is the focused removal option; Bitdefender is the stronger single-product choice when ongoing protection also matters.
The result was determined after cleanup
Gizmodo reports that every tested product removed the infections it encountered. Follow-up checks found no remaining malware in the registry, scheduled tasks, services, or browser extensions. The infections did not return after a restart, and subsequent scans were clean.
That makes the ranking less about basic removal capability and more about how efficiently each product reaches the same endpoint. The published test identified the following results:
| Tool | Test result | Reported scan time or limitation |
|---|---|---|
| Malwarebytes | Removed all detected infections | Threat Scan completed in 2 minutes 20 seconds |
| Bitdefender | Removed all detected infections | Quick scan finished in under 90 seconds |
| Norton | Removed all detected infections | Quick scan finished in under 90 seconds |
| Avast | Removed all detected infections | Quick scan finished in under 90 seconds |
| McAfee | Quick scan missed a WMI event subscription | Full scan completed in 16 minutes 47 seconds |
The source states that six products were tested, but the available material names five of them. No performance result is available here for the sixth tool.
The McAfee result is the main detection gap in the published test. Its quick scan missed a WMI event subscription, a persistence mechanism that can allow malware to restart itself. The full system scan found it, but required substantially more time.
Malwarebytes is the focused removal tool
Malwarebytes ranked first for users dealing with an active infection. Its Threat Scan removed the test infections without requiring the longer deep scan used by some competitors. The product is designed around on-demand scanning and removal rather than acting as a complete, permanent security suite.
That distinction affects the buying decision. The source reports that Malwarebytes worked with Bitdefender and Avast already installed, which is relevant when a second-opinion scanner is needed. It also reports the highest false-alarm count among the tested products and the slowest deep scan. Those drawbacks are less significant for a tool used after suspicious behavior has already appeared.
Rootkit scanning is disabled by default. Users should enable it through Settings, Security, and Scan for Rootkits. The reported test figures used default settings, so deeper scanning can take longer.
The 14-day Premium trial also requires attention. According to the test, real-time protection stops on day 15 and the application displays that status. Malwarebytes therefore works as a cleanup utility, but the source does not position it as a complete standalone defense after the trial ends.
Bitdefender is the broader one-product option
Bitdefender also removed every infection in the test and completed a quick scan in less than 90 seconds. Its advantage is coverage beyond immediate cleanup. The source describes it as a combination of removal and ongoing protection, and notes that it has the cleanest independent record among the products discussed.
Ransomware Remediation is disabled by default. It should be enabled if the feature is required. In the reported testing, it restored every file it was asked to restore, while a manual restore control allowed recovery without waiting for automatic action.
The practical split is binary:
- Choose Malwarebytes for a focused, on-demand cleanup scan or a second opinion.
- Choose Bitdefender if one product must handle both malware removal and continuing protection.
- Do not install either from a pop-up, search advertisement, or unknown download site. Enter the vendor’s address manually. Fake cleanup utilities can turn an existing adware problem into a more serious compromise.
The broader technology landscape is also moving toward cross-border cooperation, including the India–France Innovation Roadmap 2030 for technology and scientific ties. That does not change the tool results, but it is a separate indicator of how quickly the surrounding software ecosystem is expanding.
Verdict: use Malwarebytes for targeted cleanup; use Bitdefender when ongoing protection is part of the requirement. Skip any malware-removal tool offered through an unsolicited pop-up or third-party download page.
