When I try to access AV Comparatives I get the message “Your Access to This Site Has Been Limited.” I"m getting this message on both of my Win 7 machines that are connected to the same network. The 3rd computer on the network is Windows Vista with Avast Free 9 and is able to access AV Comparatives.
Laptop: Win 7 Pro, Avast Pro 9, MBAM Pro
Desktop: Win 7 HP, ESET SS 8
I understand what WordFence is, but don’t understand why it’s preventing me from viewing the website.
As i see at the bottom of your pic there is a FAQ section 
and maybe a forum…
The FAQ didn’t help much, but a Google search leads me to believe it’s an issue with the AV Comparatives site, and something needs to be modified by their admin. Oh well. Just seemed weird that neither my desktop or laptop could access it.
Are you using the correct web address for AV-Comparatives ?
http://www.av-comparatives.org/
Going by his screenshot he is using the correct url.
