I need a computer cleanup and optimization service

Hi, I’m looking for someone to clean up and optimize my computer. It’s running slowly, with cluttered hard drive, old temp files, and some unnecessary startup programs. I’d like a thorough clean-up, disk cleanup, malware scan, and optimization tips for improving performance. Please explain any changes you’d make and provide recommendations for ongoing maintenance. I prefer a calm, methodical approach and will have an external drive ready for backups if needed. Windows 10/11 compatible, with good communication and transparent pricing.
