All of our software downloads are safe and virus-free, but some antivirus programs such as Norton or McAfee still trigger a warning or block the download since it is an unknown program. To install the software, you will need to temporarily disable your antivirus or firewall program. You can find instructions on how to do this by searching Google for "temporarily disable [your antivirus program]." Once the software is installed, you can re-enable the antivirus software.
