Hi A
To stop Remote Access to your PC:
Open the old Control Panel (click your Start Button, then just type control and hit Enter)
At the top right of Control Panel, make sure View is set to icons
Click System, then choose Advanced System Settings
On the resulting dialog, choose the Remote tab and turn off any option that allows remote access to your PC . . .
Back in the Control Panel, go to Programs and Features, check in the list of installed Apps for either LogMeIn or TeamViewer, if you find either, uninstall them from there . .
That will stop anyone from remote accessing your PC
