MSDDLL.exe New Virus!!

I've seen a pretty nasty virus in last 2 days I think its a variant of Win32.Virut.Gen it spreads across the network pretty quick and will start broadcasting on any port it can find open, it appeared as a DOS attack initially but after looking at it I found MSDDLL.exe running and an up to date version of NOD32 wasn't detecting it, I have spoken with Eset and they are working on it as they believe the variant I saw had different signatures hence not yet dectected by NOD32.

Malwarebytes AV was able to detect it and appears to have cleaned a lot of it but I'm still seeing some references in the registry.

So if you are seeing something that looks like a DOS on your firewall have a peak at task manager and see if MSDDLL.exe is running
