My memories are incredibly vague, but here goes…
I saw this on TV in Finland in the early 1990s, when I was young. I can't remember whether it was a film or a TV episode. I think they spoke English.
There was a group of kids, who had a desktop computer, and somehow had contacted some alien or monster through it. I have a vague feeling that the creature was in space at this point, but might not have been. The alien spoke to them aloud through the computer, which it might have taken over. My clearest memory is that the CRT monitor of the computer turned like a head to look at one of them, and said something like "You are [that character's name]". It might have told them something about its intentions, but in any case the kids realized that the thing was dangerous, but it was too late and they had attracted its attention or summoned it somehow.
Later, the alien/monster had appeared. My only memory is of a humanoid monster, not very well visible in the dark, maybe in some woods, possibly with cheesy backlighting and smoke machine.
