I had the exact same problem a few months back. I solved it by locking my account and downloading an alternative virus scanner to find the keylogger.

 

 

 

I would suggest you do the same, as with me, my first virus scanner didn't find the keylogger but the second did, mcafee couldnt, but avira could. I would suggest you download avira (google it) for free and scan with it, it is very good. In the mean time, locking your account may stop you playing, but it is a much better option in the long run trust me.

 

 

 

Also, it asstounds me that people don't have bank pins set, i've had one since they were first released.

good idea.

 

 

 

but if he clever, he can change his IP or use proxy.

 

 

 

could work though, worth trying
