somehow someone or something has got into my pc and stole all my bitcoin.
Sounds like a personal problem to me. See my signature.
Don't come whining here again, or I will be forced to point out all the red flags in your obvious and despicable money-grab of a post.The most obvious indicator that your post is utter bullshit is this, "someone or something". What a dipshit you are. GTFO.
Why don't you try spinning your tales on the forums for altcoins? Those people are probably less intelligent than the Bitcoin community.
