To start off, I'm running Bitdefender Total Security 2013 on Windows 7.
I'm having trouble visiting a website which I suspect Bitdefender is blocking for some reason. I have tried disabling all of my firewalls, using different browsers, emptying cache, disabling autopilot mode, adding exceptions to the firewalls, etc. and nothing seems to help except just completely uninstalling Bitdefender. None of the parental settings have been activated. Also, my brother, who is on the same network, is using the same antivirus package as me, and he receives a warning but is able to access the same website.
The site I'm trying to visit is http://uac.ac/

As mentioned before, I have successfully accessed the site by uninstalling Bitdefender, so I know that's what's blocking my access.
