Now available on Microsoft's update portal
Windows Defender Antispyware: v1.43.600.0

End Windows Defender then download mpas-fe.exe then run it.

I have Windows Defender installed and use the built in updater. Is this a different program or the same thing?

I have never been able to get the built in updater get the latest update even when I ask it to during a Quick scan on my XP SP3 systems.

Maybe I'm not patient enough.

This my current version info. It will eventually update with the internal updater.

According to Calendar of Updates that update was two days ago:

Have a look at today:

Yeah I know but in a few days when I manually check for updates it will update with the internal updater. I don't care if it's a few days behind. I hardly ever scan with Windows Defender. I only keep it because I already have it installed and it's not causing any problems. I wouldn't install it again though I have several other apps I prefer to it.
