The .scr is most likely binded with some sort of RAT.
Run it, stub creator gets your computer information and details, can do anything from there. Upload files directly to victim's computer, control victim's mouseclicks, etc etc..
It could very well be a victim of a RAT sending you this, or the RAT creator himself. The way that this scam link is posted on a variety of random profiles and such leads me to believe there's one/two person/s behind this sending out the viruses manually. It could also be automated, but that is quite a bit more advanced. You can't know with these sort of things.
In previous links they did actually have an image, and that was of the Windows XP desktop background. I don't know if this file actually has an image embedded in it. Nevertheless, there's some sort of virus in it.
