Microsoft it started to delete files of CCleaner, a very popular application "optimization and safe cleaning" of Windows, like a potentially unwanted application or PUA, saying it did it for the extra 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 the process of working with Microsoft to understand why CCleaner has recently been identified as PUA. We assume that the issue seems to be grouped and we believe that we have addressed it so that our product is no longer classified as PUA ".
Microsoft says CCleaner installers offer Google Chrome, Google Toolbar, 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.
