Well, a sample with this name exists, but it doesn't work. So it's not a virus, and nothing for you to worry about.
Sophos from UK did make a warning about it in December 2001, but they did later on figure out the virus does not work.
Here's the Sophos page, describing a virus which doesn't exist: https://www.sophos.com/virusinfo/analyses/vbsgrateb.html
So there's nothing to worry about. Merry Christmas.
