Hola

Recuerda pasar por el windowsupdate.com regularmente y mantener tu sistema actualizado.

Bueno, veamos ese reporte.

Recuerda seguir estos pasos para la reparación.

1. Ver los archivos ocultos de tu sistema
2. Desactivar la restauración del sistema
3. Iniciar el sistema en el modo «a prueba de fallos» o «modo seguro»
4. Haz los pasos con todos los programas cerrados salvo el que estés usando para la reparación o limpieza.

Deberás marcar estas líneas en el Hijackthis para reparar:

• c:\windows\system32\mkneiqi.exe
• R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://websearch.drsnsrch.com/sidesearch.cgi?id=
• R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://websearch.drsnsrch.com/sidesearch.cgi?id=
• R1 - HKCU\Software\Microsoft\Internet Explorer\SearchURL,(Default) = websearch.drsnsrch.com/q.cgi?q=
• F2 - REG:system.ini: Shell=Explorer.exe C:\WINDOWS\Nail.exe
• O2 - BHO: (no name) - {5C8B2A36-3DB1-42A4-A3CB-D426709BBFEB} - (no file)
• O4 - HKLM\..\Run: [unfrfqf] c:\windows\system32\mkneiqi.exe
• O4 - HKCU\..\Run: [porncams1] C:\Archivos de programa\porncams1\porncams1.exe /nostart
• O8 - Extra context menu item: &AOL Toolbar search - res://C:\Program Files\AOL Toolbar\toolbar.dll/SEARCH.HTML
• O23 - Service: Windows Installer (MSIServer) - Unknown owner - C:\WINDOWS\system32\msiexec.exe (file missing)

Si los encuentras, deberás borrar estos archivos y carpetas:

• ]c:\windows\system32\mkneiqi.exe
• C:\WINDOWS\Nail.exe
• C:\Archivos de programa\porncams1\ (borra esta carpeta)

Después de haber hecho esas reparaciones, ejecuta estas otras aplicaciones por si se le ha pasado algo al HijackThis:

• Ad-aware SE
• Disck Cleaner
• Spybot Search and Destroy
• RegSeeker. De este programa deberás usar principalmente la opción de «limpiar el registro»

Tras estos pasos y reparaciones, cuéntanos como evoluciona el tema.

Felicidad

buen dia
