Please follow the instructions for removing worms.

Change any data that may have become compromised.

You will also need to edit the following registry entries, if they are present. Please read the warning about editing the registry.

At the taskbar, click Start|Run. Type 'Regedit' and press Return. The registry editor opens.

Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export range' panel, click 'All', then save your registry as Backup.

Locate the HKEY_LOCAL_MACHINE entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices

and remove any reference to any file you deleted.

Each user has a registry area named HKEY_USERS\[code number indicating user]\. For each user locate the entry:

HKU\[code number]\Software\Microsoft\Windows\
CurrentVersion\Run\

and remove any reference to any file you deleted.

Close the registry editor.

Check the following items

• To renable DCOM you can edit the registry, but it's better to use Dcomcnfg.exe. See Microsoft article 825750 for details.
• The HKLM\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous = "1" setting does not allow enumeration of SAM accounts and names. The default is "0". It can be changed in Local Security Policy. See Microsoft article 246261 for details.
• Check your administrator passwords and review network security.

W32/Rbot-RK is a worm with backdoor Trojan functionality.

W32/Rbot-RK is capable of spreading to computers on the local network protected by weak passwords after receiving the appropriate backdoor command.

W32/Rbot-RK will attempt to spread by exploiting the following vulnerabilities:

• DCOM (MS04-012)
• LSASS and IIS5 SSL (MS04-011)
• WebDav (MS03-007)
• UPNP (MS01-059)
• Microsoft SQL servers with weak passwords.
• Buffer overflow in certain versions of DameWare (CAN-2003-1030)
• Backdoors left open by other worms and Trojans such as W32/MyDoom,
• W32/Bagle, Troj/Kuang and Troj/NetDevil.

W32/Rbot-RK may attempt to spread with a filename of BLING.EXE.

When first run, W32/Rbot-RK copies itself to the Windows system folder as MSVCS.EXE and runs this copy of the worm. The copy will then attempt to delete the original file. In order to run each time a user logs in, W32/Rbot-RK will set the following registry entries:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
MsvcService
msvcs.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
MsvcService
msvcs.exe

W32/Rbot-RK will also set the following registry entry:

HKCU\Software\Microsoft\OLE
MsvcService
msvcs.exe

The worm runs continuously in the background providing backdoor access to the infected computer.

• Port scan for vulnerabilities on other remote computers.
• Send emails as specified by the remote user.
• Flush the DNS and ARP caches.
• Shut down and reboot the computer.
• Add and delete network shares, groups and users.
• Sniff network traffic for passwords.
