I just downloaded and ran the latest CCleaner 2.08.588 update from FileHippo and avast! never complained about it being infected.
I have never had any CCleaner download infected by Zlobe.
The user's systems where not infected via CCleaner but as Zlob is mutating so fast there are many ways that a system can become infected especially if they are not protected by MBAM Resident, SpywareBlaster, Windows Defender or WinPatrol.
