Not that it really matters, but that malware wasn't claiming to specifically be a MultiBit executable, it is claiming to be a multi-bitcoin wallet, whatever the heck that is...
Its the kind of malware that steals your coin no matter which wallet you use
I think a warning here is enough because the URL is close to the one of multibit and a google search (as well as some others) of "multi bitcoin wallet" does not lead to the malware.
I am not so sure however if its wise to post the URL here, idk. Maybe make code tags around it so it cant be easily clicked by someone that does not read.
