Yep, same thing happened to me.
It is because anygif.org is deemed as "harmful" by chrome, and someone probably linked an image from it.
EDIT: It is just a user's signature that is coming from anygif.org. I have sent him a PM requesting that he host the gif on a different site.
Don't worry, it is not anything related to the hive. While I don't believe you'll get any malware from viewing the signature, you may want to avoid viewing threads that display that warning until the signature change is made. Thanks for the report.
