I saw this movie on cable TV when I was 13 in 1997. It was about a guy whose family had been murdered and he was left for dead ( I think). He survived and took up residence in the rural of a small town, grew a beard too. He lived in a cabin with his dog and stayed to himself, only going to town for supplies and food. During one of his trips to the store one of the men who helped murder his family thinks he recognizes him and tells the other guys. Later on, the bad guys find his cabin while he is off jogging and he sees them and goes into defense mode. He was wearing an all white windbreaker or snowsuit and I think snowmobiles were used as well. I cant remember much more, only that it was a good movie :-) Hope this helps!
I remember that movie, but sorry, I can't recall the title!
