Since I do not own the Memeo AutoSync software, I don't know if it will undo the work it's already done. After you unistall the software, check your external drives for folders and delete what you didn't put there. Or go over to the Memeo forums and ask the company directly:
It some how got on to our computer. Keeps telling me I have a 25 day trial. No uninstall like other software. I have done a search and tried to delete it all. One day it appears, I delete it, the next day it reappears. How do I get rid of this? I do not need this.
