Microsoft it started delete files in CCleaner, a very popular Windows "optimization and safe cleaning" application, as a potentially unwanted application or PUA, stating that it did so for the additional software in the installer.
Piriform, the company who develops CCleaner, he says that they are discussing with Microsoft to fix the application.
"We are in procedure working with Microsoft to understand why CCleaner is recently detected as a PUA. We assume that the issue appears to be clustered and we believe we have addressed it so that our product is no longer labeled as a PUA.”
Microsoft, for its part, states that CCleaner installers offer the Google Chrome, the Google Toolbar, the Avast Free Antivirus and AVG Antivirus Free. Although users have the choice skip installing them, some could end up running software they didn't want. .
"While bundled applications are legitimate, combining software, especially products from other providers, can lead to unexpected software activity that can negatively impact experiences of users. While CCleaner app installers provide an option to opt out, some users can easily inadvertently install these bundled apps,” Microsoft says.
