The scene details I remember are the following. A young man is working with his desktop computer which is rigged in order to explode and kill him when he enters specific key content. Apparently, the explosive is detonated when the user hits "Enter". The scene moves from inside the room where the "victim" works with his PC to the outside "street view" from where the blast is seen as it blows the whole apartment/room. Hope someone will remember. Thanks.
