Google Play Protect scans ___________ apps that are installed onto a device:

Google Play Protect scans all apps installed on a device, regardless of their source. This includes apps downloaded from the Google Play Store, sideloaded apps (installed from sources other than the Play Store), and apps from third-party app stores. Its purpose is to provide comprehensive protection against malware and potentially harmful applications. While it does scan apps from the Google Play Store, limiting its scope to "Only Google Play store" or "Only sideloaded" is incorrect as it covers both. "Third party" is too vague and doesn't encompass the full range of apps scanned.
