Extract:
Stephen Toulouse, a Microsoft security program manager, said the program, known as "Bankash-A Trojan," could attempt to disable or delete the spyware removal tool and suppress warning messages. It also may try to steal online banking passwords or other personal information by tracking a user's keystrokes.
To be attacked, Toulouse said a user would have to be fooled into opening an e-mail attachment that would then start the malicious program. He said the company had not seen any evidence so far that the program is widespread.
So common sense would appear to be a great deterrent here, don’t open unknown email attachments.
