A service I provide to friends and family is cleaning up their computers when they start reporting, "it’s moving so slow!" or "I keep getting these popups." or error messages or whatever. Usually they are having a virus, spyware or malware issue. I’ve published my trade secret on how to fix this yourself. It takes me roughly 5 hours to clean a machine thoroughly. Granted, I usually do it overnight by sitting the computer beside me and taking breaks between programming tasks to evaluate the problems. You take smoke breaks; I take computer repair or social media breaks. For the service of cleaning a machine, assuring it has adequate virus protections, and making sure all the latest security patches are in place, I charge $135. In addition to software/hardware upgrades, I have replaced keyboards on laptops and even re-soldered a power connector on a laptop to its circuit board.
Yesterday a friend brought her computer and speakers by the house so I’ve added a service…speaker repair (I’d recommend just buying new ones).
