If you use CCleaner, the popular PC optimization tool on your computer, you may want to disable the scheduled tasks it has added to Windows and it’s startup item as well.

Disable CCleaner’ scheduled tasks

CCleaner can function without running these scheduled tasks in Windows:

CCleanerSKipUAC: If you’ve UAC enabled on Windows (most users disable it after installing Windows), it comes in the way and asks permission to run CCleaner. To avoid UAC dialog, Piriform has added CCleanerSkipUAC scheduled task.

CCleaner Update aka CCleaner Emegency Updater: After the CCleaner 5.33 security incident, Piriform has added Emergency Updater to CCleaner 5.36, which allows Avast to force a software update when an emergency situation occurs. The update check runs as Scheduled task on windows with the name CCleaner Update.

Security Alert : CCleaner 5.33 compromised with malware, remove it immediately

Now to disable these

  1. Visit Control Panel > System and Security > Administrative tools and double click ‘Task Scheduler’.
  2. Select ‘Task Scheduler Library’, which displays all tasks running in the right pane.
  3. Select the scheduled task and click disable button .

Note: You can delete both the tasks, but CCleanerSKipUAC get re-added again, but you can successfully delete CCleaner Update.
