I have tried to download and install the KB892519 Defender uodatem, which the
system says I need. The shield icon in the icon tray launches the isnstall
porocess, which "fails" every tiem.
I had the same problem. Here is how I worked round it. I removed Dender
via Control Panel>Remove Programs. Shut down Windows completely - not
Restart. Then downloaded and reinstalled Dender from website. Then got
message that Defender had not been updated for 25 days. The Signature
reference in "About" had gone from 1.13.1272.4 to 1.0.0.0. Then found
Article 915105 and followed instructions there. It worked !! Signature now
1.13.1276.3 in "About". I use XP Home so that may be the bug. Hope it works
for you.
