"Jim is local. It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job. He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer, Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

"I found him hard to work with (e.g. doesn't listen, pushy about doing it his way.) I was really hesitant after the estimate but he just kept pushing about it and I didn't have any other options - but I was sorry afterwards. I don't really like it, the quality doesn't seem great - but most important, it's not level. Drives me crazy and looks bad - just three panels and it's not level! Makes me nuts looking at it - feels like I threw my money away."
