I didn't see that warning when I reset my password from gmail.

I believe the attack occurred when I was using the computer, i.e. one minute I was logging in btcguild just fine, the next minute my password was changed. Both my mining computer (the one I believe was compromised) and my laptop were physically by my side.

MtGox is in the process of tracing my bitcoins now, I will continue to update this thread when I receive more info.
