CCleaner

Since Avast purchased Piriform CCleaner in July 2017, updates and installs cannot be trusted anymore.
Reports of CCleaner updates installing Avast AV ... with default opt-in

CCleaner/Avast are phoning home with user data
At first only PRO could be opted out, but more recently free CC now has opt-out.
Avast have been ducking and weaving with CCleaner since they took over Piriform 10 months ago
Portable CC has also been discontinued :(

What will they get up to next ?
Very disappointing with this very long term favorite being treated as a cash cow by Avast

CC installer used to offer Google Toolbar *opt-in" but Avast have changed that to opt-out or you get their AV and consequences of 2 AVs on your machine.
I can no longer trust Avast/Piriform ...

The end of a dynasty :(

Since Avast acquired the company its not the same. It has bloat to it, and also my Antivirus program picked up malware in the installer file; which might be a false positive. So I'm looking for an alternative now, sucks was a really good app at one time.

CAUTION: has been infected by a malware:

Don't get me wrong, the software itself is kind of okay. But I find it highly ironical that the installer installs Big Brother Google Chrome (and sets it as default browser) by default... Plus it must leave tracks somewhere, because when you uninstall CCleaner and then try to reinstall it again, it doesn't ask again to install Chrome... Pretty dirty for a "cleaning" software...

STAY AWAY FROM IT!!!!
I opened this accound just tu give this review to tell you how much I hate these guys!
It installed AVAST without even asking me!!! [YES I checked to the "more options" while installing it, I checked everywhere and never saw AVAST listed]
This company is a total failure, I will uninstall all of their programs from my PC.
Avast, Ccleaner, Speccy, Defraggler, Recuva,..,., all of them! They even spread a virus to millions of users last year. Stay away from them.
