CCleaner uninstalled most of a user’s programs without permission
CCleaner has had some issues over the years since Avast acquired Piriform’s popular system cleaner in 2017.
Issues we’ve reported in the past here include buggy software bundles, malware, pop-up ads, and unwanted privacy changes. Today a user on Reddit reports that the tool uninstalled most of his software without his knowledge.
The full post from user rounakr94 reads:
CCleaner 5.91 uninstalled most of my software when I removed CCleaner from Control Panel Programs and Features.
While uninstalling, I saw in the progress bar that some MSI, Steam and Origin files were being removed and when complete I saw that Adobe Reader, Afterburner, Aida64, Steam, Origin, Discord, HDsentinel, etc. were corrupted (not completely uninstalled). I had to spend another 2 hours reinstalling them and completely scanning my PC for any malware.
The scan eventually came back clean, and when someone asked where CCleaner was installed, rounakr94 replied that it was in the D:Applications folder, and when uninstalled, CCleaner removed all other programs at this location.
A developer on the Piriform forums responded to the situation by stating:
Having CCleaner remove everything from its installation directory is, under normal circumstances, exactly what you would want CCleaner to do. Not just its original install manifest files, but all updates, log files, etc. so that he leaves no trace of himself.
While that’s a fair point, rounakr94 isn’t convinced by the logic, stating, “Now why will CCleaner remove anything not associated with them? It looks like bad coding in the uninstaller or simply revenge from the developers for uninstalling their software.”
