There is effectively no way for someone to get into your PC via Steam. Just make sure you have a decent password and firewall turned on. UAC can be turned off in the control panel. It'll only appear for games that need to install something on a first-time run of the game. Like Terraria may need to install the Visual libraries as it's written in the C# programming language. So if you buy a game on Steam and running it the first time is not unusual for it to ask for your permission via UAC. In other words, no need to worry about it. It's no virus or anything, the games just need your permission to install prerequisites on your computer which are required for the game to work.
