Windows Defender is reporting very common anime based VAE files to be malware and is automatically deleting them. This VAE file is a pruned version of that file using the A1111 ToolKit extension, and in testing it works the same. It will not trigger detection and has been scanned by the premium antivirus software SpyHunter 5 and found to be malware-free.

Sample images were made with the same seed, prompt, and model, but switching between the original VAE file and my version. I have also included a simple difference map using layering functions in The GIMP image editing software, and a screenshot of the alert I received from Windows Defender.
