Hi, I'm looking for someone to clean up my laptop and optimize its performance. It's been running slow lately, and I suspect it has accumulated a lot of unnecessary files and maybe some malware. I'd like a thorough cleanup including disk cleanup, uninstalling unused programs, and checking for viruses. Ideally, the technician should also help with updating software and improving startup speed. I use the computer mainly for work and browsing, so I need it to be reliable and fast again. Looking for someone experienced and trustworthy.
