I don't believe it's a new variant, but rather a whole new virus
altogether. But, it's so new nobody really knows much about it.

Read about it here.

It's called Mydoom or Dumaruy. Very high risk. We just blocked all
.zips until the virus vendors release new definitions/cleaners.

Hope your day isn't as hectic as mine because of this damn thing.
