No. Because Virus Total reported two trojan on the latest version. This report was concerning the 32bit of ccleaner inside the installer and inside the portable version.
I would be happy to hear that the latest version of ccleaner is safe and clean.
Probably are false positives but I install only software submitted on Virus Total that are fully validated for malware free.
It's very hard to use software that potentially can destroy your system today (crackers, black hackers, criminals, etc).
To win this game it's necessary to be very suspicious. Sorry.
Have a nice day.
