What can be thought about DriverRestore

Last year I have downloaded on my PC (runing Under Windows 8) the scareware Driver  Restore and have paid for two years subscription. At that time I d'nt know it was a scareware and would say that it run well on my PC. Unfortunately, I recently uninstalled it by error. I would like to download it again for free at least in order to use it until the end of the paid subscription i.e. until August 2016. I d'nt know if this is possible but I'm ready to try. However I have since read several things about DriverRestore which lead me to think that it would be better not to use it. Can anyone tell me what to do ?

Many thanks
