Is System Ninja a safe cleaning program to use?

I never heard about this third-party app. The best app for cleaning in Windows or Mac is CCleaner by Piriform Company.

Try to avoid suspicious apps on the Internet. Always read the reviews and look for their reputation !

Thanks for the help asimpleman :)

First, I don't want to clean everything all the time, just some things before making backups for instance. Second, I want to know exactly what am I cleaning (deleting) away. For most, disk cleanup is enough. Another thing is that I don't let system and disks get "dirty", I use Revo uninstaller that cleanly uninstall programs without leftovers. After a new build or large updates, Disk Cleanup deletes 25 - 30GB of unwanted stuff.

i also use revo and even under the advance scan it does not always get all entries on c or in the registry.

not going to argue about it, been using revo for about 3 years now and every once in awhile it does miss traces. yes it's rare but it does happen.
