After trying a malware program that could not even locate this vicious app, I tried this - and it seems to have worked:
I changed the name of the app in Applications to jjjjjjjjjjj (of course you can use anything as long as none of the original name or ext remains).
I was asked "are you sure you want to change the name while the file is open?" I replied 'yes'.
I was then asked 'are you sure you want to change the ext. while the file is open'. I said 'yes'.
I was then able to drag the file to trash. I emptied it under 'SECURE' empty trash.
It seems that all traces are gone now. Could it really be that easy?
Oh, before I did that, I got rid of 'Google Chrome' because that was where all the **** was coming from, not Safari.
I hope this is helpful.
