First off I have got to say if everyone's customer service was anything like pchealth boost's, the world would be a better place! I came across the software from a post I saw on Facebook. I was praying that it would help my slow PC, and it did! I was so grateful, I had to sing its praises on here! It downloaded in no time, and was finding all of the my computers issues. I started out with the free version, and once I was completely satisfied with the way it worked, I got in touch with their customer service, to move up to the paid version. It was WAY cheaper than having some tech look over my computer, and it was way faster.
