tag_summary = "Your machine is infected with the 'Code Red' worm. Your Windows system seems to be compromised.";

tag_solution = "1) Remove the file root.exe from both directories:
\inetpub\scripts

and

\program files\common files\system\msadc

2) Install an updated antivirus program (this will remove the Explorer.exe Trojan)
3) Set SFCDisable in hklm\software\microsoft\windows nt\currentversion\winlogon to: 0
4) Remove the two newly created virtual directories: C and D (Created by the Trojan)
5) Make sure no other files have been modified.

It is recommended that hosts that have been compromised by Code Red X would reinstall the operating system from scratch and patch it accordingly.
