Well… it should be an English-only forum…
Could you please, go to an automated translation service, copy & paste your text and get, at least, an automated translation of your writings?
Thanks.
I can understand Spanish but it would be good if other users can help you.
It won’t be bad if you try to repair your installation:
Go to Control Panel > Add/Remove programs > avast! antivirus > Remove. Then choose Repair function in the popup window (Repair). You must be connected to the internet while repairing.
If this does not help, can you uninstall / boot / install / boot again?
