Vista - Win Defender non start?

Have been running Vista Home Basic since Mar 07, with updates on download and
notify, all up to date, have just checked. Today noticed no icon for Defender
in Quick Launch Toolbar, looked to change display view, no icon to select in
list. Checked security centre, Defender not running. Used Start, All
programmes to start defender. Opened Options, checked for Admin authority and
all users, both ticked. Unticked the admin user, selected save change, then
reversed the process to add tick, and saved, Defender icon appeared, and
almost immediately started scanning system. Whats up doc?? I now suspect
Defender hasn't run for a couple of days but not sure. Also, why no
notification from Security centre? All the other ticks seem to be in place on
the options screen, so just a little concerned about my security status.

Hi, i noticed my icon was not there at startup 3 days ago.
Windows security centre says that WD is running normally and the checkbox is ticked to place WD in the notification area.
If i make a change to my system WD does not notify me.
It does start up ok however from the start/programs list and msascui.exe loads into the task manager.

It is also set to start automatically in services.
vista home premium 32 not running live care.

Thanks

Unable to enable Windows Defender application in Windows Vista

What firewall, anti-virus application or security suite is installed? There
are some that cause problems which do not appear immediately.

Hi i tried that and nothing changed as the result were consistant. However, i have just looked at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and windows defender value data pointed to %ProgramFiles%\Windows Defender\MSASCui.exe -hide I changed it to C:\ProgramFiles\Windows Defender\MSASCui.exe -hide And WD is working fine now ??????

Hawkwind,

I'm glad to hear that you got WD working again. How strange. Both of those registry entries should act as the same location. It must be from corruption somewhere.

Thank you for sharing your results.

Hi Bob,

Using Avast AV, Windows firewall, and have also installed Ad Aware, but run
this on an ad hoc user request basis. Prior to Avast, I used AVG, and prior
to that Norton. Have removed Norton using their tool from Symantec website,
and AVG also gone.
