The malware-infected CCleaner had a version number v5.33. Luckily though, the malware only affected 32-bit Windows systems and required administrator rights for the user before installing itself to the PC.
CCleaner's author, Piriform, is owned by security company Avast, making the finding even more embarrassing. Piriform now instructs its users to uninstall the software and to download the newer, clean version of the software. Clean versions have version number v5.34 or higher.
Malware was found by Cisco's security company Telos.
