Recently, CCleaner 5.37 has been released with improved cleaning for Firefox and Microsoft Edge browsers. The surprise here is that Piriform has bundled Avast with this CCleaner update and made its installation as an opt-out (instead of opt-in).
Means, those who installed (and install) CCleaner, end up installing unwanted Avast (unless, they carefully watch and uncheck avast at the setup page footer) on their computers. This has raised some eyebrows. If you’ve Avast installed this way, you can uninstall it by visiting Control Panel applet. Remember this, Avast now owns Piriform.
Latest CCleaner version comes bundled with Avast Free Antivirus
Piriform has a habit of bundling Google Toolbar and other products with CCleaner (this is how they get revenue), Avast has also done this by promoting Google Drive, Dropbox, Skype and Chrome in the past.
Be Aware of Avast, May Install Google Drive on Your Computer
Recently CCleaner 5.33 version 32-bit has been compromised, after that, Avast has taken necessary measures and started releasing versions built in a new infrastructure with a digital certificate. It took some time for CCleaner users to recover from security incident, now Avast has surprised them by including their antivirus with CCleaner.
CCleaner 5.36 adds Emergency Updater and changes Cleaning rules
These people are liars and scoundrels. They know full well that CCleaner free edition installs Avast anti-virus with ZERO warning or consent. Just happened to me with v5.43.6522. BURN IN HELL, Piriform/Avast.
It just happened to me August 4th with v5.44.6575 installer, there was NO checkbox at the bottom it was BLANK and I simply clicked install,then when I try to shut down after install finishes it tells me avast installer is running.. SILENTLY.. IN THE BACKGROUND.. Using dell venue tablet, internet here is not the greatest and the tablet is not the fastest out there but this should NEVER happen!!
I ALWAYS meticulously check every screen and have not had one instance of accidentally installing ‘bundled’ software with ccleaner or anything else for over 10 years and have installed ccleaner alone probably over 50 times!!!!
WTF PIRIFORM NOT COOL DOWNLOADING/INSTALLING UNAUTHORIZED SOFTWARE TO MY COMPUTER!
The set up page footer does no appear on my PCs, and Avast is then installed. I am guessing this is becomes of my Adblocker removing the Avast box?.
Browser ad blockers limited to things controlling in browser only, how an adblocker can uncheck these boxes even in browser, unchecky prevents bundled software from installing on your computer. Unchecky unchecks those checkboxes.

The CCleaner installer follows a logic, checks installed software on your computer and offers the appropriate software.
Cleaner 5.43 installed avast without consent today on 2 June 2018. There was no avast in the setup footer page. There was no option to opt out of avast installation. This evil company is forcing avast without an opt out. This is illegal. This company deserves to burn in hell.
same as above! I installed ccleaner yesterday (5July2018) and ended up with AVAST despite having other antivirus ALREADY installed…no OPT OUT, no warning…and I had to fight like hell to finally get it uninstalled. Piriform lost a long time customer…
A similar thing happened to me when I installed the free version of ccleaner v5.44.6575 in July which also installed avast without my permission. I then had to uninstall avast which was very annoying. Also you need to check program files in your c drive as avast is still there and needs to be deleted there also. This is a trojan horse program!! I now keep getting an annoying message from ccleaner that “we’re worried about your online security” and “fix now” which prompts you to click on a button to install avast by the back door. This is total bullshit as I already have Norton antivirus which I love and have no need for avast antivirus!! Another off customer!!
CCleaner installed AVAST on my computer with absolutely NO check box to say I did not want it. This, I believe, is ILLEGAL and I am FURIOUS.
