Comodo antivirus bad GPG signature found error

I tried to install Comodo antivirus fedora version. I download cav-linux_x64.rpm from comodo web site. Then it is opened on discover. I click on install, after few second its displaying “ Bad GPG signature found “ error. I’m new to Linux. So can help me to install Comodo antivirus? I, using fedora 30 64 bit version.

The download is most likely corrupt and you need to download it again. If you do not have a reliable Internet connection, this could be why. I tested in a Fedora 30 container and it worked with the RPM I downloaded.
