As we reported, CCleaner was recently Hacked to Deliver Malware to PCs. There have been several ways submitted to protect against this vulnerability other than waiting for the vendor to resolve it completely. However, none as geeky and complete as the one offered by Mike Robbins.
Mike has developed a PowerShell script that detects and removes CCleaner.
