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 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 users have the option to skip their installation, some could end up running software they did not want. .
"While grouped applications are legal, combining software, especially products from other providers, can lead to unexpected software activity that can adversely affect user experiences. "While CCleaner installers provide an option to opt out, some users may easily inadvertently install these grouped applications," says Microsoft.
