I would like to manually import the virus definition file on a set of computers. These computers block outbound http requests and I'm not currently running an http proxy and I'd rather not set one up just for this purpose. It seems straightforward to automate the process of downloading the virus definition files and pushing them to these computers, but then I imagine I need to configure the computers to import the definition. 

Is there a command that needs to be run to import the virus defintions?
