Hi Rosemary,   
/Volumes/Installer 1/Installer.app/Contents/MacOS/AppYM

I’ve been suspecting you might have Malware on your Mac.
Now you have mentioned the above - AppYM -   you could have installed one or 
more variants of the “InstallMac” trojan.

Go to this Apple discussion and carefully follow Linc Davis  ‘Take the steps 
below to disable it”
