Que tal amigos, he tratado de quitar el virus que me cambia la pagina de inicio del explorador le he corrido el PestPatrol y elimina aproximadamente 40 elementos que contienen spyware, tambien le he corrido el spybot y el ad-aware y tambien encuentra algunos archivos infectados y los borra. todo lo hago en modo de prueba y con la restauracion de sistema apagado, y al reiniciar en modo normal vuelven a aparecer los archivos infectados.

Corri el Hijackthis y obtuve el log espero puedan echarme una manita GRACIAS

Hola te doy la bienvenida al Foro de InfoSpyware, empeza siguiendo los pasos de el "Tutorial de Spywares" con las herramientas Ewido Security Suite,*Microsoft Antispyware, Ad-Aware SE y SpyBot.

Pásale al menos dos de estos "Antivirus Online" y genera un nuevo log de HijackThis (pero con la ultima version de este 1.99.1) para pegarlo en este mismo mensaje y decirnos los resultados de los análisis de las herramientas.
