I have rarely seen such an obstructive software. It may be that it is quite safe. But it is also very annoying and obstructive. I had to help someone who bought the program get out of the jumble of pop-up windows. Even with a newly installed SSD with a new system, it makes the computer slow. This is not allowed to happen. The modules say version 8.58 of themselves, and elsewhere 9.04, and offered here at MU is version 8.12. This is inconsistent, and unrealistic. Also the presentation of these versions is meaningless and disturbing.
