I see a lot of issues flagged here: http://dnscheck.pingdom.com/?domain=%2Fwww.livinggreenbarrie.com&timestamp=1394892622&view=1 in the form of DNSwarnings and actual errors.
I see no iFrame flags, neither with Quttera’s.
This however could have been the main reason for an eventual general IP block: http://sameid.net/ip/192.185.73.103/ as it is being flagged as URL;Mal.

According to me you can file a report and ask for an exclusion for your domain here: www.avast.com/contact-form
then it is up to avast team to exclude your site from their URL:Mal blocking.
