Talos recently observed a case where the download servers used by software vendor to distribute a legitimate software package were leveraged to deliver malware to unsuspecting victims. For a period of time, the legitimate signed version of CCleaner 5.33 being distributed by Avast also contained a multi-stage malware payload that rode on top of the installation of CCleaner. CCleaner boasted over 2 billion total downloads by November of 2016 with a growth rate of 5 million additional users per week. Given the potential damage that could be caused by a network of infected computers even a tiny fraction of this size we decided to move quickly. On September 13, 2017 Cisco Talos immediately notified Avast of our findings so that they could initiate appropriate response activities. The following sections will discuss the specific details regarding this attack.

Don't use registry cleaners. They serve no purpose.

You DO know you sound like someone who sells shoes saying they are qualified to do foot surgery? Because if you are using registry cleaners to "fix muh box" you are frankly as bad an end user as those grandmas that click on everything whose PCs I have to fix!

If you were an actual educated computer end user? Then you would know 1.- Don't install crap on your PC, 2.- If for ANY reason you have to install crap on your PC you use an install trace program like Revo to make a log of every change to your system so that on uninstall ALL of the changes are reversed, and 3.- You should have multiple disk images both on and offline so if any serious issue happened you could restore your PC in under 30 minutes with a single click.

I'm sorry but registry cleaners can seriously screw a PC up, most do not understand symlinks for just one example and if you had actually been a competent end user frankly a registry cleaner would never have been needed because you wouldn't have had programs crap all over your PC in the first place, see rules 1-3.
