Possible virus/trojan in MDK ISO

Post by Rekrul »

I just downloaded the ISO of MDK and after unpacking the Rar files, I have a CUE file, an ECM file, a 3dslxecm.exe file which matches unecm.exe found elsewhere on the net and a file named unpack.exe, which my virus scanner identifies as "W32/KillAV.FN". I also submitted this file to the online virus scan sites listed in another thread and about 75% of the scanners used tagged this as a virus/trojan.

At the very least, this file is unnecessary as the 3dslxecm.exe file is the one needed to unpack the ECM file.

So what is "unpack.exe" and why is it in the archive?

Don't know. The NFO says that InsaneFury had it first. It also says that unpack.exe is needed to install correctly... the W32/KillAV part means that it shuts down your antivirus. Playing devils advocate, maybe early versions had a conflict with anti-virus programs so they needed to be shut down first before installing, but if the file is an ISO then you aren't going to install from the directory anyway, I don't see why that would be nessessary...

If you have unecm.exe just move the ecm file over it.

I think releases like this usually came with an unpack.bat file, which would just call the unecm.exe, adding the ecm filename as a parameter.

Perhaps someone tried to create a Win32-native executable that does the same, or perhaps converted the batch file to an executable. Perhaps disassembling the exe would answer some questions.

from my memory, i can confirm that this executable was converted to an EXE file from a batch file, using some 3rd party bat2exe software.

You can't be that wrong ;)
