scr is a windows screensaver file, it is not an exe file but it can more-or-less do anything an exe can including being a virus. There are plenty of instances of criminals sending people something that thye claim is an image, getting the victim to download the "image" and then open it. What the criminals do is either put a double file extension sneakyfile.png.scr, and hope the user only notices the png part as windows will usuallly hide the second file extension so the average user would only see sneakyfile.png . In other cases the criminals might not even bother with double extensions, just get the user to open something which they say is an image but is really an scr file. As windows(by default) hides file extensions the user wouldn't realise the file was not what it cliamed to be until it was too late. Don't download random files from random people who message you, don't download scr files and make sure to set up windows so it "displays full extensions for known file types" under "folder options".
