Microsoft it started to delete his files CCleaner, a very popular one application Windows "optimization and safe cleanup" as a potentially unwanted application or PUA, stating that it did so for the extra software included in the installer.
Piriform, the company that 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 the users have the option to skip installing them, some could end up running software they didn't want. .
"While the grouped ones applications are legitimate, combining software, especially products from other providers, can lead to unexpected software activity that can negatively impact user experiences. While CCleaner app installers provide an option to opt out, some users can easily inadvertently install these bundled apps,” Microsoft says.
