You can take it up with the hoster for that suspicious link code: <link href='-http://www.cryptodinero.com/2015/07/es-posible-tener-ingresos-de-internet.html' rel='canonical'/>
As I fear that Avast blocks your site as part of a general IP block, you have to ask an Avast team member to make an exclusion for your domain or instruct you what to do.
We aren't Avast team member, just volunteers with relative knowledge, so we cannot.
You could contact Avast via virusAT avast dot com and refer to this thread.
