Problema al actualizar antivirus Avast Internet Security 5.0

[radarman]

Hola tengo el Avast IS, y ayer me pidió que lo actualizara, al hacerlo se quedo bloqueado y desde entonces se queda congelado el ordenador cada vez que lo arranco.

Necesito una solución, gracias.

Intente una instalación limpia de avast...

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. Boot.
6. Register your free copy or add the license key for Pro.
7. Check and post the results. If, for any reason, you did not solve, try doing the step 3 in Safe Mode anyway.
