Safety of MacPaw CleanMyMac
iMac 2009 vintage, running OSX 10.9.5.
Prior to the App Store, I purchased a utility program from Apple's Web site called CleanMyMac from MacPaw, which is out of Ukraine. It is a storage organizer and cleaner. I've used it with apparent success for about 3-4 years and am now on version 2.5, but notice it has not been offered on the App Store for some time.
Therefore, I ask if it is safe to continue using or if Apple decided it is malware.
