The AV-Comparatives Stalkerware Test 2025 delivers a sobering look at the evolving threat posed by stalkerware on mobile devices. Despite measures from both the tech industry and platform providers, stalkerware-type apps, which are apps that can be installed covertly to spy on a victim’s private life, remain a critical concern.
This comprehensive assessment, developed in collaboration with Electronic Frontier Foundation (EFF), evaluated 13 leading Android security solutions against 17 diverse stalkerware-type apps. Key findings show that stalkerware persists even as providers and coalitions crack down: it’s sideloaded from developer websites, designed to evade detection, and frequently stores sensitive victim data on insecure servers, often exposing it to wider risks like public data leaks.
For this test, each security app was assessed for its ability to clearly detect and report stalkerware, not just using generic labels, but with explicit warnings tailored to support possible victims.
AV-Comparatives is an independent organization offering systematic testing that checks whether security software, such as PC/Mac-based antivirus products and mobile security solutions, lives up to its promises.
Of the 13 security products tested in September 2025, only a few stood out for detection accuracy, clarity, and responsible alerting, with Malwarebytes the only one to score a 100% detection rate.
From the report:
The results show clear differences in performance between mobile security products. Malwarebytes stood out by detecting all stalkerware testcases, achieving a 100% detection rate.
It went on to say:
Bitdefender, ESET, Kaspersky, and McAfee followed closely with 94% each, showing consistently high effectiveness. Avast, Avira, and F-Secure also performed well, identifying 88% of the test set, while Norton and Sophos achieved moderate coverage, detecting around 82%. At the lower end, G Data (65%), Google (53%), and Trend Micro (59%) missed a substantial portion of the stalkerware.
As one of the founding members of the Coalition Against Stalkerware, Malwarebytes sees this result as much more than a technical win. For us, the mission goes beyond simply blocking malicious software. Stalkerware-type apps are often used by abusers to systematically invade privacy and exert control. Their impact is highly personal, making reliable detection and safe reporting imperative.
Our participation in the coalition reflects a commitment to industry best practices: preventing stalkerware-type apps from being quietly installed, giving users detailed and honest threat information, and ensuring that every detection alert is crafted with survivor safety in mind. Scoring 100% in this test validates years of advocacy and development focused on the real-world needs of victims and their supporters, which goes beyond focusing on theoretical malware samples.
Ultimately, consistent leadership in stalkerware detection means standing alongside partners and survivor organizations to raise public awareness, drive safer technology, and provide every user with a clear path to reclaim their privacy. For Malwarebytes, achieving a perfect score isn’t just a mark of product quality; it’s proof of our commitment to your privacy and security.
