I have reported this as an FP already through the Virus Chest.

I’ve also discovered, if I right click on the system tray icon and open the virus chest from there, I get a different virus chest window than by double clicking the AIS icon in the system tray and selecting Protection → Virus Chest.

In the window I open directly from the system tray icon I can right click on the virus chest entry and select ‘Restore and add to exclusions’ and that does restore the file, and does exclude it, which allows me to continue on with my work.
