Hi there,
Sorry, I was too fast on that. Indeed the two problems that I had (notification comming from Symantec Endpoint Protection saying that the product requires my attention; and on the Symantec icon in the notification zone, a message indicating that there are several problems) disapeared.
However, I now discovered that my computer is apparently not protected any more! Opening the SEP interface, I have orange messages, LifeUpdate cannot be accessed any more, etc.
Clicking on details, I have 5 messages that are more or less (translated from French):
Upload diagnostic not working due a component avoiding intrusion
Protection against threat not working due to a error in intern configuration.
And so on.
I thus had to uninstall the Microsoft update I've installed before. My computer is now back under protection, but the two initial problems are now obviously back..
Hence, the problem remains to be solved..
(this looks like a never ending story).
Thanks for any additional help on that.
Cheers, Eric.
