Common sense would dictate that anytime anything pops up on your system that you did not install, it's time to start investigating it. It really is amazing how many times I've had to clean out other peoples PC's because they saw the pop up and just blindly clicked on it. I know, they do make them look very professional. But nonetheless, people need to be more aware of what's on their system and what programs they put on/are on them.
