How do you find out if someone is snooping on your computer remotely?
How can you check whether someone is checking out your computer using some remote tools that are hidden in your laptop or PC?
You can turn off remote access from control panel, system remote settings. Then look at recently installed programs and check there are no programs like Teamviewer recently installed. If not sure, post an image of installed programs. You can also install and run "malwarebytes" free and do a scan just to check nothing unusual has somehow been installed. Then do a full system scan with defender or whatever av program you have installed.
