Signatures [1.20.1286.5]

[Guest]

Even though Windows Defender said that the new signature file was
successfully installed, the main Windows Defender screen showed
the signature version as 1.13.1286.1. I had to manually delete the
signature file, and perform a manual update so as to get Windows
Defender show the correct signature file on the main screen.

Given all of the update problems posted by beta testers, it seems
reasonable to wonder whether Windows Defender did really update
the signature file properly or not.

Why is this thing called (Beta 2) while it is a very big backward
step from (Beta 1)?

Windows Defender Version: 1.1.1051.0
Engine Version: 1.1.1186.0
Signature Version: 1.14.1288.5

So--what have you tried so far?

Please try the resolution steps in this KB article first:
http://support.microsoft.com/?kbid=915105

If those fail with an error message, or don't solve the problem (test with
another update attempt) then:

You can download the Windows Installer Cleanup tool, and use it to remove

Windows Defender Signatures

After that removal, then retry updating--by both methods--Help, About, check
for updates, or Windows Update.
