Need help cleaning up my computer and optimizing performance

I'm looking for a friendly technician to clean up my laptop, remove unnecessary files, run a malware scan, and optimize startup programs. The goal is to speed things up and improve battery life without risking my data. I use Windows 10 on a mid-range HP laptop. Tasks include disk cleanup, software updates, uninstalling unused apps, checking for malware, updating drivers, and setting up a lightweight, privacy-conscious browser configuration. Please bring or be comfortable with using your own external drive for backups. I’d prefer someone who can explain what they’re doing in plain language and can work during late mornings.
