When I heard the news about that CCleaner was compromised, I checked my Bitdefender Antivirus report and found that inmediately after installing CCleaner 5.33, on September 4th, an executable named "mududufu.exe" was blocked by Bitdefender as a Trojan.GenericKDZ.40044. Please find attached two screen captures.
You have windows 32bit version?
Closed because all discussion about it should go in the official topic.
