Need help cleaning and optimizing my computer system

Hi there, I’m looking for a friendly tech enthusiast to clean up my desktop and optimize performance. The computer is currently running slowly, has a cluttered disk, and a few unnecessary programs I never use. I’d love someone to uninstall unused apps, clean temporary files, run a basic malware scan, and set up automatic maintenance. Ideally, you’d also advise on organizing files and maybe install a lightweight optimization tool. I’m hoping for a calm, patient approach and someone who can explain steps in simple terms. Access to the computer will be via remote session if possible or in-person at my home in Ireland.
