Did you ever log on via any kind of unsecured network, and have you verified that your system is malware-free?
Nope,I only login from my main PC & scan my PC regularly.
Edit:
Well I'm SOL,I thought so:
Thank you for your inquiry. We would recommend you to change your password as soon as possible. Unfortunately, bitcoin transactions are irreversible and we can not refund any amount of the stolen funds. As a business if Mt.Gox were to offer you a cash or bitcoin refund in compensation of this extremely unfortunate event, there would be a large increase in the number of hacking attempts to capitalize upon the possibility of financial reward.
As a further remedy, if you wish to retrieve your funds, we ask that you file a police report for the stolen goods. It is preferable for the police to inspect your computer, but not necessary. Once this investigation has occurred and a copy of the police report issued, please send a copy of it along with a notarized copy of your passport or Government issued photo ID to Mt.Gox and have the police contact us so that we can cooperate with their investigation by providing any requested information.
Please let us know how you wish to proceed, and again we apologize for the frustration and inconvenience caused.
Like the police can help,now THATS FUNNY !!!!!!!!!!!!!!!!!
I've got the IP & a wallet address the coins went to,anyone willing (or know how to) to do some detective work?? Not sure how much I could pay,but we can work something out.
Oh well,I'll earn more & keep them well hidden.
