Skype Trojan, Virus, Worm

There appears to be a Trojan/Virus/Worm on the loose that attacks Skype, and the people on your contact list.  If you receive an IM that appears to be a link from a trusted source - do not click it.

The wording in the message varies, but I have been able to grab these variations from other sources on the 'net:

If the link is clicked you will be directed to download an executable .SCR file from socsec.co.il that will install malicious code.  The system HOST file also seems to be edited to keep your computer from receiving virus updates.

This worm copies itself to the following locations, so delete these files:

%SYSDIR%\stwinsdat.exe
%SYSDIR%\odcwinst.exe
%SYSDIR%\windb32.exe
%SYSDIR%\servftc.exe

The registry is altered in order to run the process after reboot, remove these entries:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
• Windows Sysdat="explorer.exe odcwinst.exe"

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
• "Logon Settings2"="odcwinst.exe"

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run
• "Policies Options2"="o﷽﷽�ā쵨ĊⷨĂ"

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
• System Driver2=-

HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce
• "Services Start2"="odcwinst.exe"

The following registry keys are added, remove these entries:

HKLM\Software\RMX\cfg
• j="j"

HKCU\Software\RMX\cfg
• j="j"

The host file is altered to avoid contact with AntiVirus sites, and definition updates. Remove all entries from the Host file.
