No puedo instalar avast home editión

Hola a todos:
Alguien me puede ayudar en español, sobre como instalar de nuevo “Avast home editión”
El problema es el siguiente:
Al encender el ordenador aparecia una ventaña pequeña en la parte derecha inferior que ponía: “Estas utilizando un archivo VPS antiguo”
Entonces intente actualizarlo pero no pude.-
Luego desinstalé el avast en agregar o quitar programas, pero siguen quedando archivos en: D:\programas descargados\Alwil software, que no puedo desinstalar
Al intentar instalar el programa de nuevo aparece los siguientes mensajes:
A setiface error has ocurred2. Try to reinstall or contact supprt please
An error 3 (00000003) has ocured - Las performed operation was - spawning
Un saludo

I suggest an installation from the scratch:

  1. Download the latest version of avast! Uninstall Utility and save it.
  2. Download the latest avast! version and save it.
  3. Uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
  4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after you’ve run it.
  5. Install avast! using the setup saved on 2. It will be good to accept the boot time scanning. Boot.
  6. Check and post the results.

Which was your old antivirus (before avast)?

Haulero, there is no room for FUDing avast in its on forum.
If you don’t like avast. Just drop it. There are 90 millions users, most of them happy.
The problem in your computer seems not related to avast (specially because you’ve uninstalled it and used the uninstall tool to remove any leftover, if any).

I know there are millions of users happy with this product, but there are people unhappy with the product as well. I’m just telling him to be careful and make sure is going to work with his system because I don’t want him to have the same problem that I’m having right now. The problem of my computer was caused by Avast, don’t know what was going on but Avast did it and I need to fix it thats why I’m asking for help to you guys because you know about this Antivirus. Whatever Avast did during the process of installation that made my computer run slow, it didn’t fix it when I uninstalled it. I’m not the only person in this world that uses more than one antivirus at the same time knowing that is not adiviceable because no AV is perfect, one finds the virus that the others don’t thats why some people is running with more than one antivirus

Voy a tratar de traducir al español lo dicho por Tech:

  1. Descarga la ultima version de la herramienta de desinstalacion de avast! desde http://www.avast.com/eng/avast-uninstall-utility.html y no lo ejecutes
  2. Descarga la ultima version de avast! desde http://files.avast.com/iavs4pro/setupesp.exe y solo guardala
  3. Desinstala avast desde el Panel de Control (si es posible). Si por alguna razon no logras desinstalarlo, intenta iniciar el sistema en Modo Seguro y hazlo desde ahi.
  4. Ejecuta herramienta de desinstalacion de avast! que descargaste anteriormente. Si no logras desinstalar avast intenta hacerlo en Modo Seguro.
  5. Instala avast! usando el archivo ejecutable que guardaste en el paso 2. Seria bueno aceptar el escaneo al inicio del sistema
  6. Publica los resultados

Cual antivirus usabas antes de avast?

You don’t know that using 2 or more antivirus can cause problems in the system as slow? (that’s your case).

Hola que tal amigo, resulta que mi problema es que no acepta las licencia que me envian, no se por que, he pedido varias licencia y sale un mensaje que dice : numero de licencia no valido, tu sabes porque?

Haulero, your problem is reported and addressed here. If the procedure I (and others) recommended has not worked for you, please post to that thread.
And I’ll reiterate: The problem was not caused by Avast. The problem was caused by your installing more than one resident scanner. Any advice to install more than one applies to demand scanners, only, or resident scanners each of a different category.
