W32/Rbot-AL

Please follow the instructions for removing worms.

W32/Rbot-AL is a worm which attempts to spread to remote network shares. It
also contains backdoor Trojan functionality, allowing unauthorised remote
access to the infected computer via IRC channels while running in the
background as a service process.

W32/Rbot-AL spreads to network shares with weak passwords as a result of the
backdoor Trojan element receiving the appropriate command from a remote user.
W32/Rbot-AL also tries to use network exploits to spread itself unprompted by
a remote user.

W32/Rbot-AL copies itself to the Windows system folder as JACFG2.EXE and
creates entries at the following locations in the registry so as to run itself
on system startup, resetting the entries every minute:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
HKCU\Software\Microsoft\Windows\CurrentVersion\Run

W32/Rbot-AL sets the following registry entries every two minutes:

HKLM\SOFTWARE\Microsoft\Ole\EnableDCOM = "N"
HKLM\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous = "1"

W32/Rbot-AL deletes the C$, D$, E$, IPC$ and ADMIN$ network shares on the host computer every two minutes.

W32/Rbot-AL attempts to terminate certain processes relating to anti-virus and
security programs including REGEDIT.EXE, MSCONFIG.EXE and
NETSTAT.EXE.

W32/Rbot-AL also creates a log file called DCPROMO.LOG in the Windows subfolder DEBUG.
