Now I know avast! purchased Piriform and may if they want bundle the two together but as things stand there is no mention of this on the website. I start thinking 'What the Hell' as I neither downloaded nor at any point authorised the installation of avast! Other users on a forum I use have had the same problem. But this latest update crossed the line BIGTIME, downloaded the latest version updated as per usual using customise then things get weird I get popups telling me Windows security has been deactivated then another telling me avast! is my security program. I've been using ccleaner for years it's long been on my list of must have software, cleans the system checks registry, all good stuff. Avast needs to learn they do not have the right to take over your PC like this. Either that, or use an older version of Avast, or deal with the forced installs of CCleaner, or even Avast AntiVirus if you only want CCleaner. When Avast needs to update it's software (not virus definitions), uninstall CCleaner 4.19, let Avast update and reboot, Go to Task Manager in Admin Tools and DELETE the Avast Task, then reinstall the original CCleaner. If you can get a hold of the older version 4.19 of CCleaner, do what I do. But there are no issues if you turn off all monitoring, something that is not needed anyway to clean up things. They also install a 'task' in Task Manager that forces this install without permission, AND greatly slows your boot time as it does it! Avast claims that there were security issues in the older 5x versions of CCleaner, and that's why you need to update. Now that Avast has bought the company, they force installs of the latest version of CCleaner, which was never necessary in the past.

The older graphics were easier to read, and the 'results' readouts' are not as user friendly as the original version. The new 'tiles' interface on CCleaner is horrible.
