Access denied: Flashget, How can I get rid of it?

I share computer with my wife. Whenever I log off I keep on getting this error message saying “Access denied: flashget” I’m not very good with computers so these types of pop ups worry me.
This doesn’t happen to her when she logs off. Is it because she has administrator status? How can I get rid of this message? I really hope it isn't a virus. I was so irritated with it, I actually I took a picture. I hope you can help me out.
