We have been in business since 2007. We had a new website designed by a new company in March of this year. The site was doing well up until a few weeks ago when we were notified by a customer that Norton was blocking the site. We have since been notified that Avast is also blocking the site. We contacted our website provider and they are telling us they are not seeing any issues. Apple & other platforms are not detecting any problems with the site either. We have scanned the site with online scan tools like Site Lock and see no issues. How do we know what the problem is and remove any issues so the site can marked as safe? We are losing valuable traffic everyday and we’re not sure why.
