Hi jraju
I did just that and in fact, 16 updates were transfered, one of them for W.D..
Even after I have restarted the computer, now with the av not disabled, they kept comming, two or three for W.D. and the one anti-malware, arriving one at a time, all of March.
So I'm convinced that no update is missing now!
And, a few hours ago, one more for W.D., with the computer in "normal" mode, I mean, nothing disabled, everything seeming to work properly.
What really could had been was the cause of this?
Thank you very much, Boggin, Jraju and all, for your support.
