believe me, I am very good regarding security. It just can't be coincedence if so many accounts were hacked into from users machines. Just read all reports around forum. And read this post - https://support.mtgox.com/entries/20208066-huge-bitcoin-sell-off-due-to-a-compromised-account-rollback?page=2#post_20249476 - they admit they had issue where all information was leaked from their db!
