Networks

Not sure about running scripts, but you will also need to terminate the running malware process from memory before you can delete the registry key, otherwise it will just come back when you next restart the PCs. I know its not the answer you're looking for, but I hope it helps!

First thing to do, is to run a network wide virus scan to clean all the current virus' on your network off.

Next up, you can (although I recommend testing this thoroughly prior to attempting it) create a batch file with the correct registry settings and the commands to go out and delete the svchosting.exe file.
