Microsoft Defender Antivirus has detected malware in lexart model included with this extension

[halr9000]

Until this is resolved, I highly recommend switching to a different, safe model (see first comment below), and if you don't know how to do that, cease using this extension. Could be a false alarm, but safer to trust Microsoft rather than disable pickle checks.

Repro steps:

1. Install extension
2. Switch to promptgen tab, generate a result
3. In auto1111, this error is reported: AttributeError: 'NoneType' object has no attribute 'keys'
4. Windows Defender alerted me to a threat

Note that promptgen cannot be used once the file has been quarantined. So this is a critical issue even if Defender is throwing a false alarm.

I'll note that I've been using promptgen happily for months, this is the first time Defender popped up. Possible this is a false alarm, but also possible it's a newly updated model on huggingface, or a newly updated definition by MS which finds malware which had always been present. Looking at Defender, this issue started popping up 3/15.

The file may be malicious, so the program is not going to read it.
You can skip this check with --disable-safe-unpickle commandline argument.

Interesting, 3 days ago, someone submitted PR for a safetensors version on hf here https://huggingface.co/AUTOMATIC/promptgen-lexart/discussions/1

That'd be nice right about now @AUTOMATIC1111

Could you tell me where the models even are saved? I installed the models by adding the Huggingface Name into Promptgen Tab in the Settings. But I never could find out where exactly they were downloaded. That said, I let Windows Defender scan the whole Stable Diffusion Directory and also the huggingface cache in the Userfolder. There was no alert for me.
