Problemas ordenador muy lento |
|
| Buenas tengo un toshiba NB500 a 1 GB me va excesivamente lento ya que muchas veces escribo y luego salen las palabras, las paginas web tardan en cargarse y se cuelga constantemente, tengo problemas con firefox ya que no se cargan la paginas bien y con google chrome a todas hora problemas o no responde cuando pulso en alguna pestaña, puede ser viros, pero pase el advance system care y consegui una clave para el profesional, también el superantyspy a modo de fallos y el ccleaner, desinstale el antiguo antivirus e instale el AVG que el primer mes es la version completa y aún así problemas constantes,
Que puedo hacer, y muchas gracias por perder el tiempo en ayudarme Saludos Juan |

| Hola miguelferto.
Pasalé algún antivirus online,también Malwarebytes en modo seguro,y ya en modo normal descarga e instala el programa HijackThis.Lo ejecutas y le das en donde dice Do a system scan and save a log file. Te generará un archivo de texto. Copia su contenido y lo pegas aqui para que sea analizado. Cuando pongas una pregunta,recuerda refrescar la página para ver si has tenido alguna respuesta.Puedes hacerlo pulsando F5. | ||

| Muchas gracias por contestar he pasa dos antivirus y solo han aparecedio 2 supiciosus policies, y cero malware.
respecto HijackThis a mitad de analisis me se para y me dice: por alguna razón, el sistema les niega acceso a cualquier archivo hosts si hijackeddomains se encuentran en este archivo, HijackThis no puede ser capaz de solucionar si eso sucede, usted necesitará editar el archivo usted mismo. para ello, haga clic en Inicio, Ejecutar y escriba: notepad c: \ \ Windows \ \ System32 \ \ drivers \ \ etc \ \ hosts y pulse Enter. encontrar las líneas (s) secuestrar informes y eliminarlos. Guarde los archivos como anfitriones. con citas y reiniciar el sistema. for some reason your system denied acces to hosts file if any hijackeddomains are in this file, hijackthis may not be able to fix if that happens you need to edit the file yourself. to do this, click start, run and type: notepad C:\ \ Windows\ \ System32\ \ drivers\ \ etc\ \ hosts and press enter. find the lines (s) hijack reports and delete them. Save the files as hosts. with quotes and reboot. presion aceptar y el reporte que me manda es: * Trend Micro HijackThis v2.0.4 * See bottom for version history. The different sections of hijacking possibilities have been separated into the following groups. You can get more detailed information about an item by selecting it from the list of found items OR highlighting the relevant line below, and clicking \ 'Info on selected item\ '.
