I had a similar problem recently, but I had an issue since couldnt uninstall from the control panel.(Im using 64bit windows 8 btw)
I had to disable all wondershare items on startup(just like the first answer) although windows 8 allows you to do this through the task manager(Ctrl+Shift+Esc). I had two programs still running, Ive forgotten the first ones name, but the second one was DelaypluginI. You can either restart or try stopping all wondershare services (just like the first answer, although I prefer restarting, easier that way)
Then I had to eliminate all the program files manually. Since my pc is 64bit, the remaining files were under C:>Program Files (x86) > Common Files > Wondershare
After this I eliminated the files located in C: > ProgramData all the folders starting with wondershare. To access this folder you must make hidden items visible through Files Explorers settings.(in windows 8 its through View tab)
I also found a wondershare folder in the documents library.
Hope this helps.
