More Information
W32/Spybot-DA is a network worm with backdoor Trojan functionality.
W32/Spybot-DA attempts to copy itself to SSYS.EXE in the Windows system folder and creates entries in the registry at the following locations to run itself on system restart:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Windows Config = SSYS.EXE
HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce\
Windows Config = SSYS.EXE
W32/Spybot-DA remains resident, running in the background as a service process and listening for commands from remote users via IRC channels.
W32/Spybot-DA 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.

TASKMON
MSTASK
