Sometimes, anti-virus software may incorrectly flag a new or unfamiliar software or download as harmful, although it's not. Should you experience this situation, we encourage you to make contact with the product owner of the product directly.
If an owner was trying to spread harmful viruses, they would be unlikely to respond to any support requests received - however genuine owners will always seek to assure customers that their product is authentic and safe.
The owner's support contact information is on the receipt JVZoo sends you above the download link.
If you are still uncertain if a file or product contains a virus contact support and the product will be reviewed and ensure that it is safe.
