V1047 is a nasty computer virus which pretends to be a file, and when you put something in it, or near that file, it grabs it, infecting that file and the data inside. The next time you try to open a file that has been infected, it shall open it in Safe Mode, and as many people ignore it and turn off Safe Mode, that is when
V1047 strikes the computer itself, deleting and exchanging software so it can grow. If your computer owns V1047, then protect it, or update your System Management so it can handle it.
