In our garden one of the tomatoes we bought had mosaic virus. This has since spread to a few other pots. We would want to get rid of the plants and repot some new plants. How do I dispose of the plants, the soil and disinfect the pot for new plants?

There will be no disinfecting enough to keep the virus at bay. Usually, once it is established it will not leave. If there are other plants nearby, then they can carry the virus. Many plants will not show symptoms, and will be unaffected, however, many will be permanently affected and will require that the area never contain any plant that can catch it.
There are around 150 plant species that can contract the disease, so as long as you avoid them, it won't pose any kind of threat. Unfortunately, there is just no getting rid of it once established in an area, due to the way it spreads (even on plant pollen).
