Hi Weathergeek, not d2p has not been proven to be effective against viruses...yet!!
This is a quote from an announcement a few weeks back:-
"Symphony has initiated tests by an independent laboratory to determine whether they are also effective against viruses, and tests will be run on the COVID-19 virus as soon as a specimen becomes available. However, it should be noted that until such tests have been completed and verified, there can be no guarantee that Symphony's d2p technology will be an effective barrier to the COVID-19 virus".
