Win32:Delf-MBA [Trj] False Positive?

Just had this strange issue happen. Avast detected dis

9/20/2013 8:01:30 PM SYSTEM 1592 Sign of “Win32:Delf-MBA [Trj]” has been found in “C:\73f05012ee5af8e1117e09b5\81F9197F-49E4-4128-9FE3-E78898E8FF3Dmpasbase.vdm.old.temp” file.

Need this file investigated: also there was other files within this same folder location but they suddenly dissapeared even though it only chested one file. I have no idea what this is… I tried searching around AvaSt forums and found something like of that of an alias to this name and file location and type, just a different random folder address with the files nestled in it.

Need help in verifying if this is a file part of Windows Defender or not:

Windows XP Sp3 installed,

Couldn’t find anything in the registry like :


HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\RUN\ XTray.exe

I didn’t see anything odd in my WIN.INI either… so I have no idea…

Sincerely,
Brick

It’s strongly possible but… cant ever be entirely too sure:

Still trying to research… . Seems like the folder number is about the same digits.
