Is this bad? Firewall popup for winslave01 when playing Team Fortress 2

[ty1er]

I was playing TF2 the other day, and my kerio firewall pop up asking to allow this.

gameoverlayui.exe (buildbot_winslave01_steam_rel_client_win32@winslave01)

The text in the () just seems strange. I know that the "gameoverlayui.exe" is a part of steam.
Is there any way to check the "gameoverlayui.exe" md5 hash against a legit one?

I search around the net, not really finding a deceint answer.

I get extremely paranoid when wierd stuff like this happens with my pc.

thanks
