On sleep, you should be safe but it depends on your settings. If you want to be certain nobody can use your machine while you're not sitting in front of it, your best bet is to disconnect the computer from the network, hibernate or shut down. Teamviewer may still transfer files as Martin Fürholz mentioned. If you lock your PC, most forms of remote control become more inconvenient for the attacker but you're certainly not completely safe. Other software, notably Remote Desktop, interacts with your user session directly which is why you can log in with Remote Desktop even when the computer appears locked to a physical person sitting there. This is why anything seen through Teamviewer is the same as what the physical person in front of the computer would see. Teamviewer interacts with Windows as if an extra keyboard/mouse/monitor were plugged in. Any processes you have open in your user continue running and this is why you can download a file and lock your computer, and it will continue downloading while your computer is locked. From here, you can navigate to the various features outlined below.Locking a Windows computer with Windows+L simply prevents the physical user from interacting with any of the processes running within your user. Once the installation process is complete, you will then be taken to the main TeamViewer interface, which is divided up into two tabs: remote control and meeting. The initial TeamViewer setup couldn’t be easier: simply install the software, indicate whether you want to use it for commercial or private use, create a name and password for your computer, and make note of it for future reference.
