Hello list!

It's UPX 1.90 (beta) packed, but I get an other MD5-Sum:
c8448185f7bf5c6cc702f4df24d9aa33 *usb_d.exe        (decompressed)
b33ddfe16b2a11719aef76f3e24c7e04 *Kopie von usb_d.exe        (original)
The sums were created with fsum 2.5

The program has a menu:

POPUP "&File"
{
MENUITEM "E&xit", 105
}
POPUP "&Help"
{
MENUITEM "&About ...", 104
}

The About-dialog has four controls:
CONTROL 107, 2, STATIC, SS_ICON | WS_CHILD | WS_VISIBLE, 14, 9, 16, 16
CONTROL "__ Version 1.0", -1, STATIC, SS_LEFT | SS_NOPREFIX | WS_CHILD |
WS_VISIBLE | WS_GROUP, 49, 10, 119, 8
CONTROL "Copyright (C) 2003", -1, STATIC, SS_LEFT | WS_CHILD | WS_VISIBLE |
WS_GROUP, 49, 20, 119, 8
CONTROL "OK", 1, BUTTON, BS_DEFPUSHBUTTON | WS_CHILD | WS_VISIBLE | WS_GROUP
| WS_TABSTOP, 195, 6, 30, 11

String-Table:
103, "__"
106, "Hello World!"
109, "__"

After offset 0xB030 comes some socket status messages (like "Error creating
server socket", "Error creating socket"), an HTTP-request-header to domain
cjdra.com. It self puts a link to its location in
Software\Microsoft\Windows\CurrentVersion\Run.

For me it seems to be an proxy-server or something which gets its commands
from cjdra.com to perform a sort of DDos or something.
