Technical Details

A StartPage trojan can be a script (VBS or JavaScript file) or a binary application (Java applet or Win32 application). StartPage trojans in the REG file format (Windows Registry export/import file) also exist.

StartPage trojans usually modify the Windows Registry to alter browser's settings. Some will alternatively register themselves as components of Internet Explorer and therefore only activate when the browser starts. Once active, they then extract HTML pages and open them in the browser.
