Trojan/Keylogger Problem?

Recently I got a worm Lsas.Blaster.key logger. and Trojan bnkwin32 key logger. My question is: Do these worms/Trojans steal account information like Facebook/msn/Forex/aim, credit card stuff… etc. I use Mozilla as my browser. My other question is how can I get rid of them, I now they’re trojans trying to trick into buying the security,so someone help me please, I really need to know if they really do steal info.
