I purchased their software and they enter my computer. After that my computer became slow then some of the features of Windows 10 are not working correctly. Then all of the sudden after few days my computer crashed. Unfortunately I didn't get the activation key. Therefore I can't re-install it. I signed up only a trial period period then all of a sudden I was charged in my card for my 1 year subscription without any notice. I'm already unhappy with the software during my trial period and then I was forced to pay for 1 year.
