I've had a program called Trio Office show up on my laptop that, once I type a letter for instance and I go to hit print it comes up with a window that says "$7.95/yr. or $15/lifetime". It will not print my item unless I pay and I never requested this program. So, it's holding my work hostage. It has taken over all of my work in Files and Documents. I don't dare try to uninstall it for fear of losing all my work. What can I safely do?
