Why does malwarebytes block connections to china everytime I launch this game?

Everytime I launch this game Malwarebytes blocks a connection from hl2.exe to 113.105.172.61 port 58312
It happens everytime without fail, what is this all about? 113.105.172.61 doesn’t belong to any server from gametracker so I fail to see how it is a game server.

Make sure your Steam Download region isn’t set to some Asian country.

Try in Steam offline mode.

Try deleting all .dll and .exe files in game folder and verify game cache in Steam.

Having followed your instructions and effectively reinstalling the game the issue is no longer present or at least it is no longer being reported.
