Hola, el log debe ser tomado en Modo Normal para ver todos los procesos que se ejecutan en el sistema, el que tomaste está en Modo Seguro.

Por lo pronto sigue estos pasos:

- Descarga y ejecuta la herramienta FixWareout siguiendo los pasos de su manual.

- Descarga la herramienta WinsockFix y descomprímela en el escritorio de Windows, pero no la ejecutes aún.

- Cierra todos los programas, ejecuta HijackThis y dale "Fix Cheked" a estas entradas:

O2 - BHO: (no name) - {CA6319C0-31B7-401E-A518-A07C3DB8F777} - (no file)

O3 - Toolbar: (no name) - {0BF43445-2F28-4351-9252-17FE6E806AA0} - (no file)

O3 - Toolbar: emotigt - {54BECB1C-D4EA-47B2-9B56-C6768144FDD5} - C:\Windows\emotigt.dll (file missing)

O17 - HKLM\System\CS1\Services\Tcpip\Parameters: NameServer = 85.255.115.4 85.255.112.221

O17 - HKLM\System\CCS\Services\Tcpip\Parameters: NameServer = 85.255.115.4 85.255.112.221

- Es probable que al darle "Fix Checked" a las entradas 017 te quedes sin conexión a internet, para reparar la conexión ejecuta la herramienta WinsockFix, al reinicio de tu máquina puede que tengas que volver a configurar las propiedades de tu conexión.

- Reinicia la máquina y realiza un escaneo con Ewido Online.

- Pega un nuevo log de Hijackthis pero tomado en Modo Normal y uno de FixWareout.

Seguimos pendientes.

Saludos
