CMD32.exe is not a Microsoft file, from what I can find it is part of the
KWBOT worm or one of it's variants. Probably this file was quarantined by
your antivirus software, but it left the entry behind. Here are some basic
instructions for removal. If you are not 100% comfortable in the system
registry, get professional assistance and DO NOT DO THIS:

a. Click Start, and then click Run. (The Run dialog box appears.)

b. Type regedit

Then click OK. (The Registry Editor opens.)

c. Navigate to each of the keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsCurrentVersion\RunServices

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce

NOTE: All of these keys may not be found on all the systems.

d. From each key, in the right pane, delete the values if you find them:

SystemSAS system32.exe

CMD cmd32.exe

e. Navigate to and delete the key:

HKEY_Local_Machine\Software\Krypton,

f. Navigate to the key:

HKEY_Local_Machine\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

NOTE: This key does not exist on all the systems. If you do not find it,
proceed to

step i.

g. In the right pane, double-click: Shell

h. Change the text in the Value data box so that it reads only:

Explorer.exe

i. Navigate to each of the keys:

HKEY_Current_User\Software\Kazaa\LocalContent

HKEY_Current_User\Software\iMesh\Client\LocalContent

j. In the right pane, delete any values that refer to the
C:\%Windir%\UserTemp or

C:\%Windir%\User32 folders. For example:

Dir? 012345:C:\%Windir%\UserTemp

NOTE: "?" in this value represents a number that the worm has chosen.

k. Exit the Registry Editor.

Reboot the system and the warning message should not appear.

Did you recently remove a virus? You're now left with a reference
to it that you also need to remove.

See www.dougknox.com, Win XP Fixes, Clean KWBot.Worm Registry
entries.

Or read
http://securityresponse.symantec.com/avcenter/venc/data/w32.kwbot.c.worm.html
and pay particular attention to step 4 in the section headed
"removal instructions," near the bottom.
