CCleaner was detected as PUABundler:Win32/PiriformBundler by Microsoft
Despite being a legitimate program, antivirus software often flags this program as PUABundler:Win32/PiriformBundler, considering it potentially unwanted. The reason is the usage of software bundling with these cracks. These bundles not just bring unwanted software but may also be used to inject malware.
PiriformBundler Overview
PUABundler:Win32/PiriformBundler is a classification used by Microsoft Defender Antivirus to identify a specific type of potentially unwanted application (PUA) bundled with software from Piriform. Piriform is known for developing popular utility software like CCleaner. Such a promotion strategy for the program was adopted long before it was considered illegal. Nowadays, the company stopped using it, but you can find plenty of Piriform software cracks spread as a bundle.
Piriform Bundler is blocked not only because of this global ban on bundlers. Users also complain that free CCleaner, usually used as a “main” program in that bundle, performs many background operations. And background activity is not bad until it goes against privacy and users’ will. However, the CCleaner gets updated automatically without any notifications and even without being launched in any way. Moreover, users detected the telemetric functionality during this silent mode. Hence, CCleaner is an unwanted app for users who pay much attention to privacy. Piriform Bundler became banned just because it spread this unwanted program.
