I can't figure out how to remove secuirity tool rogue anti virus program. please help.?

No it would not say security tool it would have some random name, you need to find the one that does not belong and end it. Once you figure out which process is security tool then it might work. Another way is to use hijackthis and look for it there, but again you have to know how to spot it. I would try and end it using msconfig since it would be easier to find that way.
