Identifying a possible virus

I have been sent a plugin from my friend, for a mode i was saying I needed. I didn't trust him that much and decided to run it on a separate test server on here. After the plugin loaded, it made the largest log file I have seen, that not even mclo.gs would upload it. mclogs says "Failed to save log: Required POST argument 'content' not found." and i don't think thats bc of mclogs.
