Looks like you put some Spanish through Google translate. Maybe communicating in Spanish is easier: http://forum.avast.com/index.php?board=25.0

I have a Win7x64 bit and avast works fine.
Any other security software? Firewall? Anti-spyware?
If uninstalled how was it uninstalled?
What are you using for system utilities?
