Yeah, it seems it is the site itself that is triggering our AV's. Shortly after posting my last reply, I remembered that every time somebody in a forum links a picture or file hosted at ripway, I get a alert from my AV and it blocks the site.
all patches, cfw, hacks, keygens etc are viruses or malicious software don't forget all these are designed to alter operation systems or programmes that are closed source and not meant to be touched only via original vendors updates, so for the safety of your hardware AV programmes will flag most of them as malicious.
I don't think this will work as mentioned it needs to activate the DLC before it can be used, and there is no known way of doing that without the NPDRM keys.
