If you’re using an old version of CCleaner free on Windows, know this, with Avast or AVG antivirus installed on your computer Avast auto updates it to the latest version. Why? Avast does this without your permission? Find out answers from them below. First, I should warn you, you should not be using outdated software or applications, remember CCleaner 5.33 security incident! The new versions contain fixes to critical security bugs and of course, brings new features and improvements.
Avast auto updates old versions of CCleaner to new
What happened?
Apparently, one user who reported on the Avast forum found that updating Avast via the updater built-in, has updated his CCleaner version as well. “I manually reverted CCleaner on my XP system from 5.41 back to 5.09. It stayed that way for a few days… until just now, when I updated avast (via internal updater) from 17.x to 18.3… and CCleaner was “simultaneously” updated to 5.41 again.”
Another user experienced the same says blocking CCleaner Updater in Firewall hasn’t helped him either. “Apparently, AVAST are taking it upon themselves to perform the updating process,despite any or all attempts to NOT update “our” programs with NO notification & against our will/s.
Mine just updated to that version as well, even though I had the CCleaner.exe/updater blocked by my COMODO firewall. or am I mistaken? ”

Eventually, Outdated CCleaner versions will be upgraded to latest
Avast says earlier released CCleaner versions may not work well with latest applications you’re using, for instance, cites Google Chrome which updates for every six weeks, as an example.
“We have decided to upgrade all outdated CCleaner versions (v1.xx – v5.20) to the latest version. Portable versions were excluded. ”
“The reason is that old CCleaner version may not work as expected for for the latest software (your CCleaner is old, but users expect it will work perfectly also for e.g. latest Chrome which is updated every 6 weeks), maintenance of the latest version is much more easier for both developers and support and also from possible security issues. ”
Use CCleaner Portable for all good reasons
To avoid CCleaner Standard from installing bundled software such as Avast Free Antivirus or Google Chrome, its better for you to use CCleaner Portable version.

Windows 10 doesn’t allow running outdated software either
When we tried to run CCleaner installed version 3.27 on Windows 10 (note: Avast not installed), we noticed Windows prevented its execution and the compatibility assistant showed this notification ‘ CCleaner can’t run on Windows’.
The notification said ‘This app may decrease PC Security or performance. Check for an updated app that runs on this version of Windows’. Of course, we have uninstalled the CCleaner after that.

Here we feel user shouldn’t be doing such practices where Avast is equally responsible and shouldn’t have upgraded CCleaner without user consent even though CCleaner is their own application. After all, these are two different applications running on user’s computer.
