Does my SD card have a virus?

I can view all my photos on my memory card when its in my camera (SamsungL313), but when I try to upload them onto a computer either with a card reader or my USB cable it blocks it and says "fukkb shortcut to MS-DOS program 117kb". If I have a virus, how do I get rid of it without losing my photos? I can't even transfer them to a memory stick or a file, so if anyone can shed any light for me, it would be a great help!
