Need help cleaning my computer and optimizing performance

Hi there, I’m looking for someone to clean up my computer and improve its performance. I use a Windows PC and occasionally run into slow startups and freezing when I have too many tabs open. I’d like a thorough cleanup: remove temporary files, uninstall unused programs, run a malware scan, organize files, and optimize startup programs. Please also advise on basic maintenance tips to keep it running smoothly. I’d prefer someone patient who can explain steps in simple terms and provide a short post-service checklist. If possible, bring or provide the necessary software tools to complete the tasks efficiently.
