How can you tell if another computer other than your cable provider is linked to yours?

I took my computer to a shop, since then I've had odd pop ups.Like an alert that another account is opened for my e-mail.Is there an way I can check to see .And a easy way I can undo the link if there is one?


Thanks for your help!
