impossible to scan

Is Someone know why Avast (4.6) cannot scan a EXE program include in a set of Sound card installation (Sound Blaster 16, an old card) ?

Also, java files (exe) are not scanned, avast said that “the archive is corrupted” ??

Hi frantzgac,

This forum has a search function, if you search under archive corrupted you get many results and ditto anwers to your particular question. There are many legit reasons for a file not to be scanned by avast, password protected, file cannot be read, etc.

Hi Polonus,

I juts reproduce the message of avast scanner. But the file is not an archive. It’s an exe DOS file very old and trivial (without password). I van normally execute it and that prove it is not corrupted an can be read. I’m surprised that Avast identifies it as an archive. May be the error message does not cast exactly the cause.

A exe doesn’t mean it can’t be a archive or compressed file.

Sure an exe can be a compressed file. But this one, created in 1993 for DOS OS is a pure executable file. The 2 first characters are MZ as all executable DOS file.

Did you have NAV 2003 in this system in the past or any other Symantec product?

No, I don’t. NAV is too expensive. Neither Symantec Product. It’s a clean and recent system (two months older). Very interesting question !

I have a similar problem in the past so I’ve asked you.
I was introducing my 1st post here in avast! forums with the same problem: http://forum.avast.com/index.php?topic=707.msg3417#msg3417

Can you post the contents of these Windows Registry keys in your system?

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers\VDD
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\VirtualDeviceDrivers\VDD
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\VirtualDeviceDrivers\VDD
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Control\VirtualDeviceDrivers\VDD
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet004\Control\VirtualDeviceDrivers\VDD

You should have aswMonVd.dll and no one s32evnt1.dll in these registry keys (if you have all of them).

I really don’t understand this statement. The MZ header just says it’s an EXE file - which we already know. It can be a self-extracting archive, or an exe-packer packed executable.
For some reason, avast! cannot unpack it (could be an unsupported or somehow modified version) - therefore the message.

To Igor

You are rigth. Self-extracting archive looks as exe file. But this file executed doesn’t extract content but runs and show a DOW Window. It’s a 1993 built file. I think self extracting file was very rare to this year.

To igor

sorry : read “shows a DOS windows”

What I have

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers\VDD
C:\Program Files\AlWil SoftWare\Avast4\AswMonVd.dll

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\VirtualDeviceDrivers\VDD
C:\Program Files\AlWil SoftWare\Avast4\AswMonVd.dll

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\VirtualDeviceDrivers\VDD
C:\Program Files\AlWil SoftWare\Avast4\AswMonVd.dll

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Control\VirtualDeviceDrivers\VDD
absent key

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet004\Control\VirtualDeviceDrivers\VDD
absent key

They’re all right.

No problem… ok, too.

The problem seems to be at the file itself. Can you send it to Igor for analysis?

Hello

sure I can send the file. You find it to :

http://frantzgacogne.free.fr/ftp/install.exe

or (the same )

http://frantzgacogne.free.fr/ftp/install.zip

thanks for your interest

The file is packed by an executable packer, but the format or version is not supported by avast! (so, it’s unable to unpack it). Nothing to worry about.

I guess I’ll remove these error messages from the future versions of avast!, as they seem to confuse quite a lot of users.

Ok, thanks Igor :slight_smile:
