We have over 100 systems affected by this and none of the proposed fixes seem to work for us. We shut down most of our 1200+ as soon as we realized something was going on - not knowing if it was a virus or what we figured this was the safest path to take. So we really do not know how many systems... Most that we know for sure are Windows 7 Pro ... as far as we can tell so far, no Win xp systems were affected. Please provide fix asap because if computers are not online by Monday am we are in deep trouble. We already have folks expecting to be able to work in the am.
