More Information

W32/Spybot-CB is a network worm with backdoor Trojan functionality.

W32/Spybot-CB attempts to move itself to AUTODISC.EXE in the Windows
System folder and creates entries in the registry at the following locations to run
itself on system logon:

HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce\
Windows Data Server = AUTODISC.EXE

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
Windows Data Server = AUTODISC.EXE

W32/Spybot-CB also attempts to copy itself to the startup folder of attached
network drives and can be used to record the keystrokes on the compromised
machine, effectively acting as a keylogger. This worm can also be used to initiate SYNFlood attacks.

W32/Spybot-CB remains resident, running in the background as a service
process and listening for commands from remote users via IRC channels.

W32/Spybot-CB attempts to terminate various programs including the
following:

NETSTAT.EXE
MSCONFIG.EXE
REGEDIT.EXE
TASKMAN.EXE
NAVAPW32.EXE
MMC.EXE
NAVAPW.EXE
