HOCI for Norovirus?

We had an unconfirmed case of Norovirus in the house this week (could have been anything but I’m taking Noro precautions since it’s the most contagious)- but our babysitter is coming this weekend. We’ve let her know and she isn’t scared, but I want to make sure she does NOT get it. I’ve been using Briotech Extra Strength HOCl, it just says it’s a “cleaner & deodorizer” but according the ingredients it has 0.05% hypochlorous acid, with 500 PPM and according to the internet all that’s needed is 200 PPM to kill Noro. But I’m just concerned since this brand isn’t listed as a disinfectant specifically? It is not under the EPA registered cleaners, but I’m not sure how often that is updated or the requirements for it to be listed. I am using strong 6.00% sodium Hypochlorite bleach for every surface I can but for spraying EVERYWHERE including my couch/carpets/ color safe objects I would like to use the HOCI. I do not have any money to buy anything more although I am open to a cheap safe around kids & pets product I can get from Walmart in a pinch if needed.
