Behavior Shield tried "eating" Internet Explorer

As I was starting my usual morning surfing, there was a pop-up message from Behavior Shield that it wanted to remove Internet Explorer! (There was a bit more to the message, but I didn’t copy the details.) IE would not function.

I remained calm, and was able to add IE as an exception to the Behavior Shield. Even after doing so, IE continued to balk, until I temporally disabled Behavior Shield, at which point IE came to life. IE then continued to function, after I re-enabled Behavior Shield. Hopefully, it was a one-time FP/glitch, that won’t recur.

Am I the only one who experienced this today?
