Here's a mnetion from 2011:

(http://answers.microsoft.com/en-us/windows/forum/windows_7-s...)

So, someone using an OS heavily targeted by malware decides not to use anti-malware software, and to have javascript and apparently java enabled in the browser, and then chooses to visit an URL advertised in a chat window - that URL is unknown to that person, does not match the URL they're on but claims a link to the URL they're on, etc etc.

It's a shame someone got robbed, and the responsibility is clearly on the criminal to not engage in criminal behaviour.

But come on; don't just give them your money.

EDIT: I just read the first answer to the MS post above. It's baffling.

> On reflection the best and easiest recourse might be to just tell AVG to "ignore" this "infection." Is this thing actually a virus? or an infection? I have seen no operational problems, nothing in chkdsk, sfc, Registry Mechanic, etc., to concern me.

Totally unrelated to MtGox but: someone has anti-malware software. That software tells them it's found an infected file. There's no evidence this is a false positive. Rather than wipe and re-install (a distressingly unpopular choice) or using anti-malware tools to clean the infection the advice is to train the software to ignore the infection.

MS is stuffed. There is nothing they can do to repair their malware reputation when the users are that stupid.
