I don't understand. OP, you held that many BTCs and left the unencrypted hot wallet in plain sight on your computer? Knowing this, you still opened a blatantly obvious virus/trojan?
What do you possibly think you can get from opening a MtGox2014 file? I think if you gotten a program that was named walletstealer.exe, you'd open that too.
Dude. Don't kick someone while he is down. In fact don't kick someone EVER.
A guy was rubbed after getting hammered by the Gox incident!!!!
OP: I'm very sorry to hear about your losses and I feel bad for you - thank you very much for sharing and warning everyone with your personal experience.
