System Sweeper and Windows Defender Offline will not update or scan

    Diskusi Umum

  • As of Jan 29, 2012 (possibly earlier), the bootable media created by Microsoft System Sweeper and Windows Defender Offline for 64-bit systems will boot, and immediately show that the definitions are out of date. The built-in "Update" feature will download but not install the updated signatures.

    I have tested this on both CD and USB media, on two different 64-bit systems (Win 7 and Win Vista). I'm trying to create a MSS or WDO disc to clean up a third system; the two machines I'm testing on are clean.

    I know these tools are free and beta, so I'm getting what I'm paying for. But in the past System Sweeper was the sure-fire solution to clean up a rootkit infection; it worked great.

    Can anyone else verify that both these utilities are broken?

    Standalone System Sweeper v 1.0.856 64-bit with definitions in mpam-fex64.exe v1.119.905.0.

    In mpam-fex64.exe the mpavbase.vdm and mpengine.dll are dated Jan 17, and mpavdlta.vdm is today, Jan 29.

    Downloaded from https://connect.microsoft.com/systemsweeper and http://windows.microsoft.com/en-US/windows/what-is-windows-defender-offline with both tools resulting in the same failure.

  • I just updated my latest DART build successfully, so maybe they found the problem? Try it out on your end and see if it works...

  • yes, i can confirm for both. Even after reinstalling on a clean usb and downloading the full 250 k, when i boot up with the usb it gives me all red and says i must update.  multiple tries at updating and it never finishes....says it failed due to an internet error....

  • Verified - same problem here.

  • Same problem here as well. I also found this problem affects older DART images that I have built that worked just fine before. This leads me to believe that the problem is rooted in the definition package installer itself. Something wacky going on there...

  • I just opened up a support ticket with MS on this.  They are aware of the issue and hope to give a status update by mid-week.

  • April 24 2012, didn't seem fixed to me, I have the same problem where the scan is not available, the update starts dowloading and installing multiple times, and then finally gives an error regarding the internet connection. I created the 32 bit version USB from a clean pc to run on another which is infected.

  • I've been trying to get a WDO image to boot and scan properly since January. I've gotten each new version, created a bootable USB drive.  Always the same result - boots fine, loads the UI, fails due to out-of-date definitions, and update fails due to lack of network connectivity.   

    This time, I tried a few extra things: tried booting with a wired connection: No love.  Tried a Mod'ed WIM image that brings up networking: Nope.  Tried it on another x64 machine (WS2K8R2): WOW!  It scanned perfectly.   After scan, tried Update: same no network issue, but boot & scan is repeatable.  This got me to thinking.  Now that it's worked once - will it boot on the original machine, perhaps its now marked "updated"...

    Back on the original machine...

    USB boot dev plugged into same USB port it was created in, boot/scan: FAIL; move to next open USB port: FAIL; next port: WORKS! Scans completely, though Update still doesn't work, the out-of-date bug is worked-around.

    Of 4 available USB ports on my laptop, only one works:  Port_#0001.Hub_#0004.

    In each of the other USB ports (Port_#0002.Hub_#0004, Port_#0003.Hub_#0001, Port_#0004.Hub_#0001 ) the out-of-date definition bug always prevents scan.

    Don't know if it'll help anyone else... but worth forwarding the the devs.   Its interesting that only a port[0] works...
