Fast virus definitions are typically used as part of a general security campaign where fully certified virus definitions are deployed under normal circumstances, and fast virus definitions are more likely to be deployed at the perimeter during epidemic situations. Most customers should not use Rapid Release virus definitions as their default desktop deployment package, although this is technically possible. Rapidly propagating virus definitions are easier to deploy as standard procedures to edge devicesx, such as mail servers and Internet traffic gateways, since the risk associated with false positives of these elements only leads to blocking of traffic, and not to disruption of desktop computers.
Descriptions for rapidly spreading viruses are no longer available through LiveUpdate.
