I give Carlos Diaz a five-star rating because he is professional, persistent, and very knowledgeable. He helped me rid my computer of malware that was slowing it down. Initially, I was reluctant to let someone I didn't know access to my computer but I also didn't want to be without my computer so I took a leap of faith. It was so worth it!! Carlos is honest and diligent. It took him considerably longer than expected to remove unwanted programs and malware but he worked into the night until everything was running smoothly. I am going to hire him to debug my other computer. His price is fair and he is wonderful to work with. He even followed up the next day to make sure everything was OK and sent me information about how to avoid downloading unwanted programs in the future. If you need help, Carlos is the one to call. I highly recommend him!!!
