FLAME isn't a virus, it is software from Brazil, just like LUA is from Brazil.
"Tool prototyping in the FLAME platform is based on the Lua scripting language. Lua is adopted in FLAME as an extension language: its interpreter is embedded as a library into the measurement agents. On the one hand, the Lua interpreter gives to the scripts running in the agents access to active measurement primitives through a high-level, minimalist API. On the other hand, the measurement agents and the measurement API are implemented in C, preventing significant overheads in the measurement results due to the execution of Lua scripts."

Looks like that link's since been updated to make it clear that this is a completely unrelated piece of software called Flame that just happened to use LUA too, with it being very unlikely that any code could be shared between the two. Basically, the name's just a coincidence.
