Maybe if you go to their website through HMF, you won't have the anti-virus issue. Just click on NURSERIES and enter "newflora" in the SEARCH field. It will take you the the nursery page on HMF and then you can click the button to visit their website. That's the way I've always done it, so I didn't expect that there might be a problem.
The site does list the licensed nurseries, many of which you may have used in the past.
