Greg, Dave,

A repeat of my activities earlier (file download via IE8 *and* wget) shows =
the problem to have now gone away.

I've still got a copy of the "bad" file - same file size as the "good" setu=
p.exe but with a earlier timestamp:

-rwx------+  1 585728 Aug  5  2008 setup.exe_bad*
-rwx------+  1 585728 Sep 10 11:56 setup.exe*=20

A "file" (OK, not difficult to fool) shows both to be:

MS-DOS executable PE  for MS Windows (GUI) Intel 80386 32-bit, UPX compress=
ed

---

A browser hijack is possible (and something I'll look into), although the f=
act I'm now able to download without problem (via both IE8 and wget) sugges=
ts otherwise. I've not rebooted in the meantime and besides, a download via=
 wget was giving the same problem earlier. This latter observation may be e=
xplained by local proxy caching, though.

The fact that the "bad" setup.exe crashed when executed suggests it might b=
e corrupted in some way. Could some form of proxy issue result in transient=
 data from two independent sources (the genuine setup.exe plus some transie=
nt "ebuddy" traffic) being merged into a single file?

Interestingly, I see multiple WinXP crash dialogs when attmpting to run the=
 "bad" executable. Not something I've seen with other crashing applications=
 before.=20

If either of you guys are sufficiently interested, I can send over a gzip'e=
d copy of the bad file.

Thanks for the interest,

Mike
