Problem installing/running Windows Defender Offline

Greetings all,

I currently am using Avast AV on my Win 7 64 bit machine. No known problems. I decided to try out the Windows Defender Offline 64 bit version. Downloaded 800k file and ran which prompted me to insert blank CD and it then downloaded and expanded the files onto the CD. All seemed to work fine.

Next, I rebooted from the CD and I got the white bar (progress meter) along the bottom which said "Windows is loading files". Took couple of minutes. One time it made it about 90% through loading. Next time it made to where it said starting Windows. THEN...

It appears the video signal to my monitors dies (which means computer freezes??). Screen went to black and I got a couple of Samsung monitor error boxes (Analog/Digital/Analog/Digital) on the screen which the monitor does when no video feed. Then the monitor went into powersaving mode since no feed. The computer's hard drive light was flashing once about every two seconds. Once I left it for about 90 minutes in this state and it never moved on.

So, ideas? Do I need to run MSE as my AV program with Windows defender? Bad install? Anything else?

Thanks

So you had to recover by using the physical power button or Ctrl/Alt/Del?

Bad burn?

Hard hold down on the power button. Ctrl-Alt-Del did nothing. The computer came up just fine.

Windows defender is not compatible with win7 . It's replaced by MSSE.
See this site:
Windows 7 Compatibility for Security: Anti-virus Software Programs: Download Software Updates

Unless newer versions of Win 7 are different than the original release:

Windows Defender is built into Windows 7, so it is compatible.
It gets turned off when the optional (MSSE) MS Security Essentials AV is installed.
Windows Defender protection is part of MSSE protection.

Installing another AV such as Avast does not turn off Windows Defender...
I have a PC with Avast AV and Windows Defender enabled.
No problems here.

I see Windows Defender listed in Control Panel...take a look...

I never used Windows Defender Offline, so I can't help with that.

no disrespect intended

My understanding is that Windows Defender Offline is a renaming of MSSS.

Windows Secrets review:
Windows Defender Offline

I am just trying it to improve rootkit detection.

Cool, thanks for the link. It's interesting reading.
To me it sounds like MS is re-using the Windows Defender name and this is in a "Transition Phase" right now.
Windows Defender Offline is nothing like Windows Defender...but not yet ready to replace MSE.

Anyway, to make sure I understand correctly,
your problem is you tried Windows Defender Offline,
you had an issue starting windows the FIRST time after WDO, but now everything works.
You can now boot and start Windows OK?

Using Avast + Windows Defender should not be a problem...
MSE should also work ok, but Windows Defender is not needed with this.

Sorry
I didn't intend to mean that is not compatible but when MSSE is downloaded WD will be turned off.
Thank you David and sorry again.

Sorry, i misunderstood

I'm pretty sure this compatability issue is not really related to the OP's problem (unless I misunderstood - which is not unusual ), because the OP is trying to boot off of a CD or DVD and therefore not even loading the installed OS. It's going to load the OS contained on the CD/DVD itself. So as long as the bootable CD/DVD can read the filesystems of his internal drives he should be good to go.

I think I would look at the burn (use something like ImgBurn The Official ImgBurn Website, 4x max), quality of CD/DVD media, and integrity of the iso that was downloaded.
