I know you 'get what you pay for' and boy did I with the "FREE" version. Not only did I download what seemed to be a cumbersome application for plan reviews, but I also downloaded TEN (10) infiltrations to my WINDOWS operating system as well. My virus scanner was able to 'clean' these infiltrations, but the four hours I used this software were a complete nightmare for me, turning me off from ever considering a PURCHASE of any version of MediaFire. I see other reviews stating 'no viruses' but that was NOT my experience.
