Basically a bunch of scientists at a research facility in the snow covered mountains discover some sort of virus or creature, and this special ops team is sent in to investigate/exterminate whatever killed all of the scientists. I think the virus may have turned the scientists into zombies.
I know for a fact that it is not resident evil, it may be in Russian, not sure though
I remember another one< where there were black spots under armpits and people were getting mad because of parasytes. Mad and killing each other. Maybe it is X-files episode.
