We had Christopher update and clean up our PC. It had been almost 4 years since we purchased the PC. It was very slow. He was able to identify the source of the problems and clean up the malware, cookies, temp files, viruses, etc that were slowing down the PC. I was able to ask many questions about the PC including safety issues related to PC's, passwords, etc. He was very professional with all of his interactions. I would highly recommend Christopher for both personal and business computer service needs.
