There is something wrong with Pokejungle and a user who is in the thread you want to read is hotlinking an image from Pokejungle. It'll clear itself up overtime as this was an issue with Pokebeach images from MRAS' signature last week.
Found the user that triggered the Notice and sent him a PM asking him to remove the image. Though it he doesn't I can't really do anymore than that as its a browser issue not an actual viral/malicious threat. We can only wait for Pokejungle to sort out the issue themselves.
