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