I should note that I always manually run CCleaner since I killed its ability to actively monitor anything.
CCLEANER PIRIFORM 5.42 UPDATE
This makes me wonder if deleting the cookie which magically showed up under the cookies in CCleaner which are not to be deleted, could somehow be involved in making CCleaner automatically update itself. I just ran the installer again, and I don’t see any setting in the installer for automatically downloading updates. When I installed this version, I do not recall any setting for automatically updating CCleaner, just the setting to check for updates. The one thing which I did after installing CCleaner version 5.41 was to delete the Avast cookie which showed up under the cookies to keep. I have been thinking about your post all morning long since it has been really bugging me. Perhaps they just took it upon themselves to update C.Cleaner on peoples pc’s
CCLEANER PIRIFORM 5.42 PC
To the best of my knowledge, I don’t have any Avast on my pc apart from C.Cleaner so I don’t understand how an Avast anti virus update could affect my version of C.Cleaner. No multi-page installation required, no third-party offers, no hidden tasks quietly added to Windows Task Scheduler, & no automatic forced version updates. (Win 圆4 users can delete the 32-bit CCleaner executable supplied inside the folder.)

Simply extract the downloaded ZIP file, scan it for possible malware, & run either the 32-bit or 64-bit executable inside the folder when you feel ready to do so.
CCLEANER PIRIFORM 5.42 INSTALL
It is possible to avoid the Avast offer (as well as the hassle of having to install CCleaner during every version upgrade) by using the self-contained portable build. You would see the Avast Antivirus offer, if the below registry value does not exist:

The Avast Free Antivirus (opt-out) offer that appears during CCleaner installation is not tied to CCleaner setting itself to keep the Avast browser cookie. I do know that even without installing Avast, the latest versions of CCleaner do set a browser cookie for Avast which you must remove from the cookies to keep. Now 5.42 they giving their frinedly help – “Where appropriate, CCleaner Free may recommend improvements to your system’s antivirus protection” AKA AVAST My regret is not keeping screen shots of VirusTotal results. I don’t recall specifically but believe this was days rather than hours. All the popular (in my experience) AV companies EXCEPT Microsoft were listed as detecting the CCleaner infection by the time I gave up. Eventually, “I have better things to do” came to mind.

The detecting AV companies grew in number. I kept checking, ostensibly to check how long it took Microsoft to report the problem. One of the detecting AV companies was NOT my regular AV so I kept checking the VirusTotal link and saw the numbers grow. VirusTotal reported three AV companies detected a problem (obviously, one of those was Malwarebytes). Due to Malwarebytes report, I again referred the file to VirusTotal. Nothing alarming was reported.īy coincidence, I ran a Malwarebytes scan early on the day the infection started to be detected. As is my habit, I ran the update installer through VirusTotal before installing.
