My Most Popular Cleanup/Restoration Service

 Comprehensive computer repair/technical support/PC cleanup and restoration that encompasses every aspect of your operating system's performance. I use multiple free programs to perform 100% thorough virus removal along with all malware, spyware, rootkits, etc. I turn off all the Windows based apps that mine your personal data, clean out all temp and log files, old backups, everything that's clogging up and using space unnecessarily. I install all needed updates, then fine tune and optimize performance to give incredible speed and reliability to your system to make it perform even better than new. I then offer an unheard of 6 month warranty on my service! 

In 6 years, I've gotten 41 reviews on Yelp, all of them 5 Stars! They're only featuring 13 right now

Just need questions answered, or need tutoring?

 If you have questions about what level of computer repair or technical support you may need and why, I'll happily answer your questions in a very friendly manner. I am a Windows 10, 8 and 7 expert, and can shed light on the things you're dealing with in regards to these systems. Make the call, it's FREE! If you'd like tutoring on how to use your computer or programs, I can help you figure out the easiest way to do that as well. There is a charge for that service.
