Include a notice if "tcejbo gninwapS" pseudo-virus was detected in the JSON#2968

It’s no longer connected to a server, but it still replicates itself across any other loaded objects and can cause lag. I run a cleaner every so often and I still get fresh hits, so I think it’s worth notifying people about. Ideally TTS would then clean the json itself, but the current tools are pretty good at that already so perhaps it’s not necessary.

I run this.
