One culpret that others have fingered is the switch syntax on the
command
line, when the host OS is Windows 2000.
However- since you were able to run the unmodified command
interactively and
get an effective scan, I think the most likely issue with the scheduled
scan
is the credentials under which it is running.
On my system, if I make the hidden task visible, and right click it and
choose properties, looking at the Task tab, the Run as: is set to NT
AUTHORITY/SYSTEM
If yours does not read that way, try changing it. If it does, consider
setting that to an administrator level user with a password on your
system,
and set the password for that user, using the set password button.
It is also possible that changing these credentials and then re-setting
them
to NT AUTHORITY/SYSTEM may make a difference--there have been some
other
posts in relation to credentials which suggest that it won't hurt to
try
that, at any rate.

Scheduled Task kicked Windows Defender off at 4:00 PM but Windows
Defender
never ran (as before). So it's not the 'check for updates' function.
I
did
check my Firewall (Microsoft OneCare Protection Plus) and Windows
Defender
was defined and 'Allow'ed.
I'm at a loss. I'll wait for your response.

Additional Information: I copied the Scheduled Task entry for
Windows
Defender into a Windows "Run" window and it ran OK. I was also able
to
monitor it running in the Windows Defender window.
The run command was:
"C:\Program Files\Windows Defender\MpCmdRun.exe"
Scan -RestrictPrivileges
The only change that I made this time was to unselect the 'Check for
updated
definitions before running'. I re-sechuled it for a 4:00 PM run.
We'll
see
what happens then.
Bob F
:
Looking at my previous update: Scheduled Tasks kicked off Windows
Defender
task at 2:00 PM as it should have. Windows Defender never ran.
At
2:02 PM
I started a Windows Defender Scan that lasted 2 minutes and 14
seconds.
The
Windows Defender window then indicated the completion of the scan
that
I
started.
Hopefully this (this reply and my previous reply) will help
determine
what
happened and lead to what is happening with the scheduled scan not
occuring.
Bob F
:
Just for clarification--you won't see anything happen on a
scheduled
scan,
unless you open the Windows Defender UI while the scan is in
progress, and
let it stay open for a bit, so it can connect to the process
that is
actually doing the scan and display the progress.
So--it isn't clear to me whether the scan is really not
happening, or
whether it might be happening, but that there is a problem
updating
the UI
to show the last scan date correctly.

I found it in 'Hidden'. Did not scan though. I changed it to
1:00PM.
Still
didn't scan. Task Scheduler indicated the change. Task
Scheduler
says it
ran
at 1:00PM but Windows Defender 'Last Scan' doesn't indicate it
and
I saw
nothing happen at 1:00PM.
Windows Defender build is:
Windows Defender Version: 1.1.1347.0
Engine Version: 1.1.1372.0
Definition Version: 1.14.1452.3
Bob F
:
In the task scheduler window, go to Advanced, in the top
menus.
and check
"View hidden tasks."
You should then see a job for the Defender scan. "MP
Scheduled
scan."
What build of Windows Defender are you on--top number in
help,
about?
What's the scheduled time/date of that job? If you
right-click it
and
tell
it to run, what happens?
--
The OS is Windows XP Professional SP2 running all the
latest
Microsoft
updates. The Task Scheduler is started but there is no
entry
for
Windows
Defender in it.
Bob F
:
I need more information here - What OS are you running? Is
the
task
scheduler service started?

Hi,
Does anyone know why Automated scanning doesn't scan
despite
its
selection
in tools/options?
Thanks
