Hola te doy la bienvenida al Foro de Spyware, empieza siguiendo los pasos de este tutorial (http://www.forospyware.com/t8-.html), en particular los pasos de descarga y uso del spybot y de adaware se

Pásale un antivirus online pues tu pc está contaminado con virus, usa (este por ejemplo) (http://www.forospyware.com/announcement.php?f=12) y anota todo aquello que elimina o no puede eliminar.

Paso 1- Apaga el "restaurar sistema (http://www.forospyware.com/showpost.php?p=45&postcount=2) "

Paso 2- Activa la opción de "ver archivos ocultos y de sistema (http://www.forospyware.com/showpost.php?p=46&postcount=3)"

Paso 3- Con todos los programas cerrados ejecuta el HijackThis y dale "FIX Checked" a estas entradas:

Paso 4- Reinicia e inicia en "modo a prueba de fallos (http://www.forospyware.com/showpost.php?p=47&postcount=4) " (modo seguro)

Paso 5- Busca y elimina todos los archivos que indico en negrita manualmente (aunque puede que alguno no este)

Paso 6- Usa el Disk Cleaner (http://www.forospyware.com/showthread.php?p=48#post48) para limpiar cookies y temporales

Por ultimo reinicia el pc y vuelve a ejecutar el hijackthis para ver si aun tenemos que limpiar algo mas.

Sigue tambien los pasos de este post (http://www.forospyware.com/t4067.html) para eliminar el virus.
