Has anyone come across this? Avira has started picking it up, apparently on boot sectors of my C: and D: drives and HD0 and HD1 (dunno what they are
). Google seems to throw up a few instances of people attempting to fix this and having partitions go missing, but I can't seem to find any straightforward way of actually killing the thing. Malwarebytes doesn't even find it. Any ideas guys?
Thanks!

Thanks!
