Was the exact same trojan(Win32.Backdoor.Delf.cir) that was flagged.
I have ZAP anti-spy set to update and scan daily, so was flagged on my system this morning.
Have checked the ZA forum and there is one post entered today with same issue, but no replys as yet.
IIRC it was only in past 7-10 days that I updated to latest CCleaner version.
Cheers
