Windows Defender Update

[Guest]

Could anyone tell me how to update my Windows Defender definition
files offline ?

Could I dowload the update just like antivirus virus definitions
update file ?

One more, Windows Defender cannot be updated through proxy servers
with password security. Any solution ?

Thank you.

A workaround for the proxy servers is to allow free access to
update.microsoft.com, I believe.

For manual updates--see the URL's that Engel posts regularly--most recently
in the post directly adjacent to yours.

Interestingly, (or not)--this page:

http://support.microsoft.com/ph/11952

appears to have a link to the information you are looking for--in KB article
923159--but that article is not available. Looks like it was published on
October 25th, and has since been recalled.

Is your problem with Windows Live OneCare, or Windows Defender, or both?

If it is OneCare, have you tried their support?

Hi,

my problem is in Windows Live OneCare, i can't update the antispyware
definition, i asked in the one care forums and they sent me here to ask for
help.

regards

Michael

P.S. this is hou it looks like tuesday http://mmantz.de/defender.jpg
i had some trouble installing my bt usb stick and i had to install my backup
from okt 23, i had to do that a few times, now the bt stick works fine, but i
can't update the definition for antispyware, only 1x worked the update, but
since i had problems with the bt stick, i had to install the backup but the
update wan't work anymore :/

Are you on version 1.5 of OneCare--can you check the version number via
Help, About?

If you are on the version which integrates the antispyware into OneCare, I'm
not sure I know the locations of the files involved for this fix--I don't
presently have a machine with that version installed.

Here's what I think should work for you:

go to a command prompt in the folder Windows Defender is installed
in--typically this is c:\program files\windows defender.

If you don't have a Windows Defender folder--do a search under program files
for mpcmdrun.exe.

In the folder in which mpcmdrun.exe is located:

mpcmdrun -RemoveDefinitions -All

mpcmdrun -SignatureUpdate

(hit enter between, waint for completion then do the next one--the second
one will take some time--perhaps 5 minutes or more.)

Let's see if that does the trick.

Hi,

the first one was ok, but when i do the second one, it takes one second and
it ends...

oh i forgot, onecare version 1.5.1851.8

 

[Bill Sanderson MVP]

OK--so it sounds like you found the executable in the expected
location--thanks for confirming that. I ran that version of OneCare for a
short time on Vista, but I had some troubles with its firewall and my
wireless set up and I ripped it out rather quickly.

This sounds like a problem with AutoUpdate at this point.

What happens if you go to Windows (or Microsoft) Update and do an express
scan?

That should bring you current definitions.

Are you aware of any problems with AutoUpdate on this system?

Is it current with all critical patches?

 

[Guest]

i made aesterday a update, november stuff was updated, where can i make this
express scan, i can't find it on the update page of microsoft...

 

[Bill Sanderson MVP]

Hmm--yesterdays updates should have done the trick.

OK--here's what to do.

Note the time.

go to http://update.microsoft.com

and hit the top button, which is labelled "express" in english.

See whether you are offered definition updates to Windows Defender, and
whether the install is successful.

If it does not succeed, do:

Start, run

notepad %windir%\system32\windowsupdate.log

(and hit enter)

Maximize the window, scroll to the very end of the file.

Then scroll back up to the time that you initiated the update.

highlight and copy and paste that tail end of the file to a reply here.

It is possible that my lack of German will be a barrier here--but let's see
how it goes.

i never saw on the update page something that is related to one care, there
ic no log file for the updates....
i am a little bit confused,because when i was experiencing with the driver
for my bt stick,i had to install the backup a few times, and 1 time i was
able to get the updates, why not now? i remember that i hit in one care the
update button a few times and it worked once but only that time,the bt stick
made some trouble and i had to install the old backup again and since than
not :/

 

[Guest]

Hi,

now i am @ home and i started onecare and the update works now )

[Bill Sanderson MVP]

Excellent--thanks for letting me know--all should be well from now on, I
think.

 

[Guest]

but no one can tell me why i wasn't able to make this update since tuesday :/

 

[Guest]

Hi Michael,

I can tell you this:

In Thursday 9 Nov. was the updªte for Signature 1.14.1828.5

In Tuesday 14 Nov. was NO Updªtes for WD, until Thursday 16 Nov. with the
Updªte 1.14.1836.1

Update is still rather erratic at present. It comes out as and when MS
programmers feels like doing something!! I got mine earlier today -
hooray!!! Yippee!!! I can now rest for about 7 days!! On a second
thought, they might send another one tomorrow!! It is an unpredictable
affair as it stands. They must all be busy planning for Bill's
retirement next June!!

You're right--in that there isn't a set schedule for updates--they will be
more frequent if hot issues arise--a false positive that needs fixing, or
some high-profile adware that they want to add coverage for, perhaps.

Autoupdate works well for this--just set it and forget it. When Engel posts
a new update, I usually don't have it yet, and like pavlov's dog I go do a
manual update just to verify Engel's information. but on office
workstations I just let them run and look every once in awhile to see if
they are staying current, and they mostly do.

You had, in the past, been able to update the definitions.

You then had trouble with the "bt stick" and had to recover from backups
several times. My supposition in the advice I gave was that something about
the definitions in place was corrupted, and that removing them would allow
normal updating thereafter.

That seems to have worked, with the exception that your first attempt to
update via the command line didn't appear to work. However, when you
checked back some time later when you got home, the autoupdate had
functioned and you were up to date.

 

[Fat Kev]

they will be more frequent if hot issues arise

are you suggesting that these "hot issues" aren't as frequent as claimed
by security experts? We are always told that there are new variants of
spywares (and viruses but this is a different topic altogether)
virtually everyday but you appear to suggest that they are not as
serious as claimed in the press. Have I understood you correctly?
