It looks like Microsoft released a patch yesterday that addressed "Security updates to the Microsoft Scripting Engine and Microsoft Edge." Looks like it's for Windows 7 and Windows 10, and likely Windows 8, Windows Server (various), and possibly Vista and even XP, if they're still shipping patches for XP. So everyone is potentially affected.
I just need to determine why and how the TD is affected. Sigh. Microsoft.
Thanks for the info everyone. I'll keep you posted.
