It may be the case that you do not have anything in the ~/Library/LaunchAgents folder, but normally this Malware also stores files there as well. You should check this location by going to Finder > Go > Go to Folder, and copy and paste ~/Library/LaunchAgents into that text box. If there are files in there post that screen shot first, so all the problem files can be deleted at the same time.
The process will start by starting in Safe Mode

In your LaunchDaemons folder, these 2 files will need to be deleted and the other folder is fine:
- com.InitialProgram.system.plist
- com.InitialProgramd.plist
Again, verify the other folder first and post that if there are files there, so we can delete all the bad ones at the same time.
