Re: I got hacked after downloading a file from https://multibitwallet.com

His AV/Firewall probably did its job, the problem is that, despite the warnings, he allowed the program to be installed, and he didn't immediately disconnect from the Internet.
I would not agree with that statement, many people learn from other people's mistakes, and I see no reason why it could not be the same in your case. You looked for software that had been abandoned for years, you ignored the security warning of your security software and after all, instead of taking urgent action, you went to a party. You are every hacker's dream.
