Thanks for the report! :)
Can you send me a screenshot of the report on Discord (Sunija#6598)? My windows defender doesn't find anything there, so I cannot check myself. :(
And are you sure that it's the requirements checker? :3 There is a known issue that some of the AI models are falsely flagged as threats.
Also, in case somebody is interested, that's the whole script of the requirements checker / starter: https://github.com/GothaB/invokeai_starter/blob/main/invokeai_starter/MainWindow...
