Quote:The infected version of CCleaner, 5.33 for Windows, was made available for download on Aug. 15, and its cleaned version, version 5.34, on Sept. 12. The infected version of CCleaner Cloud was made available on Aug. 24, and a clean version on Sept. 15. The Mac and Android versions of CCleaner do not appear to have been affected.
An Avast spokeswoman told Reuters that 2.27 million users had downloaded the infected version of CCleaner, and that 5,000 installations of CCleaner Cloud had received the tainted update to that software.
If you're on version 5.33 of CCleaner, which states its version number in its top left corner of its interface, your best bet may be to roll back your Windows system to a snapshot from before Aug. 15, as your system may have been compromised since then. At the very least, make sure your own anti-virus software is up to date.
Those without the option to restore a backup should check if their CCleaner is 5.33. Yung notes that that Piriform is updating all versions of its software up to non-malicious versions, but users can download a new copy here.
