I currently have v3.07 which I installed on May 21, 2021. I was doing some selective tag updates using an Action I created to copy the artist tag to the album artist tag. These files were recovered from my old Ipod Touch. I was able to do about half of the files when I got a message from the Acronis software that it appeared that MP3TAG was perpetrating a ransomware attack. This never happened with the older versions of MP3TAG. I don't really think there was an attack but something in the new version must be doing something to the mp3 files that makes Acronis think it is.
Acronis did a recovery of the files in question. I did a scan of the files and my system to see if there were any viruses or malware but all seems OK.
Any Ideas as this is somewhat concerning.
I was unable to capture the messages but if it happens again I will and add them to this post.
