Hello Geo, we had a few reports where users were claiming the same, i.e. that the com.taeffect.Espionage3 folder does not exist.
And each time I would do a remote session, I found the folder, removed it and all was fine. So, whereas everything is possible, I would kindly ask you if you could check for the folder once again. Note, it is not the system or root library folder, it is your home library folder, which you can reach exactly like described in your post.
Alternatively, you can launch terminal and run this command
sudo find / -name *com.taeffect.Espionage3* -print
this command will first ask you for your account password, just type it, it will show no characters on the screen, but that is expected, so just type it and hit enter, this will then make the find command running, which will scan your entire hard drive for the aforementioned folder and report it if any found.
Let me know how it went.
Rgds
