I just scanned the zip file and the unzipped file, but no virus was detected. It was scanned by Windows 11 Pro with the virus definition file (1.371.895.0) created this morning and the latest virus definition file (1.371.920).
No changes have been made to the uploaded Lovely Composer ver.1.2.6 file from the beginning.
The virus definition file seems to be updated at least once or twice a day. If possible, it would be more helpful if you could tell us the version of Windows and the version of the virus definition file when the virus was detected.
