It's almost certainly a trojan.

I ran it, and it didn't appear to do anything.

(Of course, my sniffer, regmon, and filemon had another story to tell.)

While it sat there "hung" it was advertising itself... to ICQ users:

Basically, it looks like it's a trojan/worm that uses ICQ users (i.e.
people) as it's transport. A brief glance at the registry and file access
indicates no obvious attempt to "install" itself. It does a bit of poking
at the registry, IE files, ports, and modem settings, but I beliebe that is
because it looks like it's using the IE code to pull and post web pages per
above.

The ICQ user id's look random for the few I checked. There is no obvious
pattern. It just kept trying over and over again, until I killed it via
ctrl-alt-del (there was no window.)

I used NAI's SnifferPro, but any Windows sniffer should work. FileMon and
RegMon are both available via www.sysinternals.com .

As I said, it looks harmless, but don't blame me if you run it and it eats
your hard drive.
