Enterprise Manager and PureMessage customers will be automatically protected at their next scheduled update. At the time of writing, Sophos has received just one report of this Trojan from the wild. Information about Troj/Adtoda-A can be found at: http://www.sophos.com/virusinfo/analyses/trojadtodaa.html Description Troj/Adtoda-A is a backdoor Trojan. When first run, Troj/Adtoda-A will display the following two messages: "Setup was not able to continue the installation. An illegal copy of Windows Operating System was detected on this computer. The computer informations is already collect and will be post as this computer name: (name of machine)" "The operating system will not work properly before you get a permission after you complete the penalty! For any detail informations, Please contact the following link: http:\\www.microsoft.com\~msproduct\~watch\~piracy10 \secureID=OS_wiNver_532Fg32_ap12nt04A" After the user clicks "OK" on both of these messages, Troj/Adtoda-A installs itself and activates the payload. This inverts the screen and freezes the machine so that is needs to be rebooted. In order to run automatically when Windows starts up the Trojan creates the file C:\Windows\system\winupd32.exe and the shortcut C:\Windows\Start Menu\Programs\StartUp\System Update Service.lnk pointing to it. These files will cause the payload to be run again on system boot. Troj/Adtoda-A also attempts to modify C:\boot.ini to prevent debugging.
