How can I stop this process from trying to launch every 10 seconds?
I finally figured out where the files were: they were in hidden folders and I don't/didn't know how to use Finder's normal search to look for hidden files. I read that to find where these files are, I had to use Finder's Go -> Got to Folder feature and type the location you want preceded by the ~ character, i.e. ~/Library/ApplicationSupport/RealNetworks and then the applicable folder/file. Once in this folder, I could use Finder's normal search feature to search for files with "wondershare" and "AnjoyTunesHelper" in the name. I found a bunch, deleted them, rebooted and now my system.log file is nice and clean!
