- Trojan Horse
PHP.Sysbat is a Trojan horse, not a virus. Trojan horses do not replicate. PHP.Sysbat only executes on computers with PHP interpreters. (PHP is a server-side, cross-platform, HTML-embedded scripting language.) It cannot be contracted by simply visiting an infected Web page.
PHP.Sysbat modifies the Autoexec.bat file so that the next time the computer is restarted, the command to format the hard drive is executed. The Trojan will also append text to C:\Config.sys and to other files with the .sys extension that are located in the C:\Windows\Command folder. Finally, the Trojan tries to delete C:\Windows\System\Wsock32.dll.
