Beware!!!! I purchased the program, ran it, and then left the computer for two days...when I came back it ran a scan and identified "hundreds" of issues to fix. Having purchased only the single scan they were not fixable. But that raised a question of how can a computer be "fixed" and two days later end up with hundreds of items to fix even thought it was not used? So maybe you need to purchase the year subscription or maybe it really didnt fix the computer. I purchased it trying to fix an audio issue which it did not fix nor identify. So for me it was a no go. Just beware.
