I'm looking for a skilled computer tech to clean up my PC, delete unnecessary files, optimize startup programs, and run a quick malware scan. My desktop runs slowly after several years of use, and I want a fresh start without losing important data. Please back up essential documents if possible, organize files, and provide simple suggestions to keep it running smoothly. I’m available on weekdays; please indicate preferred time and any requirements you have regarding access to my machine, software you’ll use, and whether you can work remotely or in person.
