Hi. I did a download of https://cdimage.debian.org/debian-cd/current/i386/iso-dvd/debian-10.4.0-i386-DVD-1.iso with Firefox 79.0 under Ubuntu Linux and after completion it is marked with a red sign claiming that it contains a virus or other malware. I don't know why FF did that or how it came to that suggestion but i wanted to let you know this. I deleted the file now and can't undelete it. Kay
