Geraldo came to clean the computer of malware but quick troubleshooting proved the operating system was corrupted. He took the computer and overnight wiped it clean and installed a clean operating system and reinstalled all my files. When hooking up the system back home, he quickly connected the wireless computer and everything was was 100% and like new in no time. He was reluctant to accept any money beyond his quote for cleaning malware even though he did much much more work.
In short, Geraldo was efficient, clear, and honest. I'll call him again.
