FIRST
Run netstat -b and look for any suspicious connections to either no-ip.org or some random IP from some program you've never installed. Once you get the hostname, do a DNS resolution on it and grab the IP. You now have the attacker's IP. Alternatively, you could grab the entire list and post it here so some seasoned professionals (like me) can look through it. Feel free to report them to their ISP or what Slick was going to do, report it to the FBI.
SECOND
Look up "darkcomet RAT remover tool". Download and run this. I've had this bullstuff happen before and it's easily removable.
