Piriform released CCleaner 5.50 yesterday and it comes with the long awaited ability to block the program from automatically updating to a new version.
Users are now reporting that CCleaner is partially broken after upgrading to Windows 10 October 2018 Update (version 1809). A fix is expected to land soon.
Reports are coming in that Piriform is forcing CCleaner to update to the latest 5.46 version even when users had configured the program to not perform automatic updates. To make matters worse, once the users were upgraded to the latest version, their privacy settings are reset to default, which is to send usage data.
CCleaner 5.46 was released yesterday and aims to fix all of the problems that led to the fiasco with the previous release of CCleaner 5.45. With this release, Piriform has added settings that allow you to actually disable their background monitoring process and to disable the sending of anonymous usage statistics.
It has not been a good week for Piriform's PC cleaning tool CCleaner. With the release of CCleaner version 5.45, it was quickly discovered that the program's "Active Monitoring" component, which is utilized to send anonymous usage data back to Piriform, could no longer be disabled.
Avast has revealed new details about the 2017 CCleaner hack. Speaking at a conference in Mexico, the company's researchers said they uncovered new evidence to suggest that the hackers who breached CCleaner's infrastructure were preparing to deploy a third malware strain on infected computers.
Earlier today, Avast published a full list of companies affected by the second-stage CCleaner malware, as part of its ongoing investigation into the CCleaner hack that took place last week.

The CCleaner hack that took place over the summer and came to light this week might have been carried out by an infamous cyber-espionage group believed to be operating out of China.
