Perhaps a false positive? And that's a lot of API calls for something that does nothing...

Well, Kaspersky detects it as a "PE_patch" format file, and most of the API calls seem to be related to file i/o and registry checks, so who knows?

<edit> From a quick look with Process Monitor, it looks at two interesting registry keys:
HKLM\SOFTWARE\Blizzard Entertainment\Internal\Protect Memory
HKLM\SOFTWARE\Blizzard Entertainment\Internal\Debug Memory

If "Protect Memory" is set to 1, the program ends right away. In all other cases I tested, it does a bunch of not-very-interesting stuff then exits. *shrug* it doesn't look malicious based on what it's doing, unless it's being clever about it.
