Avast Blocking my site in a new server

in the last week, we moved our site babalufashion.com to a new dedicated server, and since that, avast started blocking the site. We have another mirror of it for testing in the same server, and the testing site is not being blocked.
We scanned the site with urlQuery, this is the result: http://urlquery.net/report.php?id=137775
As the site is an exact copy of the one in the old server, we don’t know why is being blocked. The only thing that changed is the hosting server, so please, tell us at least why is being blocked or is there a way we can know why?

Hi Praxis,

Robtex saw at least 18 hosts on your IP address: http://www.robtex.com/q/y?q=65.75.133.142.
This information is outdated, you probably inherited a bad reputation from one of these sites.

Here http://www.avast.com/contact-form.php?loadStyles is a webform you may use to contact avast about your problem.

Best regards,

Only issue I see here is a location header redirection. The location line in the header above has redirected the request to: http://www.babalufashion.com/spa/pages/home
IP PTRL does not resolve - ambiquous http://cidr-report.org/cgi-bin/as-report?as=AS36444

Contact avast as said,
