According to Dr. Web, it spreads through USB disks and the internet, and Dr. Web has great solution to that problem: "Dr.Web Office Control access restriction system: Restricts or completely prohibits access to Internet resources and removable devices, and therefore, excludes the possibility of a virus invading via those sources." "Users should only have access to the local resources they require to perform their jobs. It's no use trying to convince staff that flash drives are dangerous. It is much easier to centrally disable access to such devices."
