Malware warning from Bit Defender re possible "ransomware behavior" (encryption of files) by Musescore 3

While using Musescore 3, Bit Defender popped up a warning: "Ransomware behavior detected. The process C:\Program Files\Musescore 3\bin\MuseScore 3.exe manifests ransomware behavior and was blocked."

Several files were encrypted. Bit Defender unencrypted them, but then the Bit Defender message popped up again.

The encrypted files are iconcache_16_.df, iconcache_32.db, iconcache_idx.db, and acb021ed125a0fe3.bin.

Is this normal behavior? I've used Musescore for several years and haven't encounter this previously. One option for me is to tell Bit Defender to ignore this in the future. Should I do this? Many thanks.
