I think it is probably algae. Algae is green and slimy and likes to grow on wet areas like mold. I would make a dilute vinegar solution and spray it on the pavers. The vinegar will also kill any weeds that want to grow in between the pavers.
I took care of a puppy with parvo at home. She recovered slowly, it takes time for her digestive system to heal and for her to feel better. She will start to eat little bits of gentle food slowly and you will notice that everyday she will have a little more energy. It took about 2 weeks for my puppy to heal and start running around and being herself. You have to be patient, and a little TLC helps too. There are a lot of good ideas online about treating a puppy with parvo. They were great. The vet gave me the meds (antibiotic and another)and I did the treatments at home with the over the counter meds (anti diarrhea med, pepto bismol, pediolyte ) and the prescription meds.
Take them and a photo to your local state university extension. Master Gardeners have training in identifying bugs. Find your local extension and call them.
The best thing to do is to switch laundry detergent. I now use Nellie's which is a natural one without a fragrance. It removes all of the old film that you did not know that was on your clothes from detergent and fabric softeners. The clothes are fresh and do not need fabric softener anymore. You only need a tablespoon per load. It is does not damage the ecosystem. There are probably others that are similar. Look it up online. I bought the large one and I do not need to buy anymore for a couple of years.
