The shoutedbeats-tk trojan is only one of the many versions of mIRC-based trojans going around at the moment.

If you've been infected with that specific trojan, you could try this remover program (warning: use at your own risk!). However, please note that if you have been infected, the attacker has had full control over your system, so this remover tool is only the first step - you should definitely use recently updated anti-virus software as well (and that's always a good idea anyway, you might already have other infections on your system).
