I get so many of these similar emails from all over.. blockchain.info, spendbitcoins etc they are all spoofed and wth a .jar vrus but annoying.
I can imagine quite alot of people probably do get fooled
I think many people do not have Java installed on their machines, but I could be wrong.
Will we loose BTC if it have BTC stealing viruses? Roll Eyes
The idea is, after the user open this virus. The virus will send your btc to another address (steal).
If you just ignore these mails you wont have any problems.
