My system was slow, my browser were freezing a few times an hour, and my anti-virus would not run. Joel gave my pc a tune up and removed my anti-virus, which I was unable to do. In the end, my anti-virus was installed properly, but this was the only improvement. He even contacted me the next day to check on my system. When I told him that the issue had worsened, he advised me that my hard drive was dying. Overall, he did the best he could, but I would have preferred he let me know how serious he felt the problem was sooner.
