Actually this type of problem is pretty common in Europe, most banks have to deal with malware that threatens their customers. One of the most advanced keyloggers out there is currently URLZone, which can also perform MitM attacks and transparently re-routes money transfers, defeating iTan (index transaction number) systems (see http://www.finjan.com/MCRCblog.aspx?EntryId=2345 ).

There are several approaches to stop (or at least make it more difficult) this attack vector. A prototype of a system that implements the techniques described in your blog posting was presented by IBM Zurich about a year ago, see http://www-03.ibm.com/press/us/en/pressrelease/25828.wss for details. Other manufacturers implemented similar approaches, where some kind of trusted device is attached to the machine and also the banking card of the customer is used to verify transactions.
