Hola JosephBurro,

Descarga la herramienta SDFix y guárdala y descomprimirla en tu escritorio pero no la ejecutes aun.

(Es posible que el antivirus que tengas instalado te advierta de una infección en esta herramienta, es debido al tipo de código pero no te preocupes por ello, permite el paso de la herramienta)

Reinicia eh inicia en "Modo a prueba de fallos" (modo seguro)

Con todos los programas cerrados ejecuta el HijackThis y dale a esta entrada:


O4 - HKLM\..\Run: [Windows Internet Browser Services] internet64.exe
O4 - HKLM\..\Run: [NvGraphicsInterface] C:\DOCUME~1\PCJAIM~1\LOCALS~1\Temp\38.exe


O6 - HKCU\Software\Policies\Microsoft\Internet Explorer\Restrictions present
O6 - HKLM\Software\Policies\Microsoft\Internet Explorer\Restrictions present
O6 - HKLM\Software\Policies\Microsoft\Internet Explorer\Control Panel present




Ejecuta SDFix.exe en el escritorio, se creará una nueva carpeta en el escritorio, entra en dicha carpeta y ejecuta el archivo "Runthis.bat" luego, presiona la tecla "Y" para que comience el chequeo, al terminar, se creará un archivo dentro de la carpeta llamado Report.txt, copia y pega lo que indique ese reporte acá.

Descarga CCleaner y ejecútalo usando primero su opción de "Limpiador" para borrar cookies, temporales de Internet y todos los archivos que este te muestre como obsoletos, y luego usa su opción de "Registro" para limpiar todo el registro de Windows (haciendo copia de seguridad).

Reinicia y nos contas los resultados.

Salu2

Ahi esta el report del SDFix me borro un trojano, pero no se el motivo porque dejo el 38.exe y aparte puso otro 53.exe, me podrias decir el porque, muchas gracias piedra poor tu gran ayuda pero todo sigue igual nuevamente muchas muchas muchas gracias...!! una pregunta mas, skytel no es un malware ???

SDFix: Version 1.137
