[citation][nom]Christopher1[/nom]Does this attack work on Windows Vista
http://en.wikipedia.org/wiki/Windows_Vista ? Or does the included security stop attacks like this in their tracks before they even get started?[/citation]
The malware targets user files (.doc, .txt, .xls, etc). If you're thinking of something like the UAC, it won't stop it. UAC works on system files/configuration and doesn't protect user files. How about other users' files? Vista won't prompt the user, but will deny the malware (unless it's implemented to bypass user restrictions).
Kaspersky probably already has signature for the caught/detected malware (probably, detected initually as suspicious software). But if the author uses a new kind of packing/encrypting for the malware, throw in some anti-debug and anti-kaspersky mechanism, then the new variation slip right thru.
