Preview bug?

New bug this morning.  I can't preview any files associated with Abobe? The preview window in both Illustrator and windows explorer say " The file you are attempting to preview could harm your computer" . Don't know if there was an update or something. i made no changes from yesterday when it was working fine? Please help! Windows 11 PC.

I uninstalled the Oct securty update and it fixed the issue. I have paused any future updates. Hopefully they fix this issue.

Hi FS412,

 

Theres an update lately from Windows. It was 15 Oct. update.

 

You can uninstall that specific update to resolve this issue. Hopefully it will work for you!

It looks like an update to Windows is causing this issue. Look at these posts from Microsoft:
