AV-Comparatives - Stalkerware Test 2025

[harlan4096]

Here is what we found:

Stalkerware detection is still a mixed bag. Notably, Malwarebytes detected 100% of the stalkerware products we tested for. ESET, Bitdefender, McAfee, and Kaspersky detected all but one sample. This is a marked improvement over the 2021 test, which also found only one app with a 100% detection rate (G Data), but the next-best performing products had detect rates of 80-85%. Google Play Protect and Trend Micro had the lowest detection rates in the 2025 test, at 53% and 59% respectively. The poor performance of Google Play Protect is unsurprising: because it is the anti-virus solution on so many Android phones by default, some stalkerware includes specific instructions to disable detection by Google Play Protect as part of the installation process.

There are fewer stalkerware products out there. In 2020 and 2021, AV Comparatives tested 20 unique stalkerware products from different vendors. In 2025, we tested 17. We found that many stalkerware apps are essentially variations on the same underlying product and that the number of unique underlying products appears to have decreased in recent years. We cannot be certain about the cause of this decline, but we speculate that increased attention from regulators may be a factor. The popularity of small, cheap, Bluetooth-enabled physical trackers such as Apple AirTags and Tiles as an alternative method of location-tracking may also be undercutting the stalkerware market.
