Win32:Delf-MZG

If you have just updated your anti-virus program Avast and now it's detecting viruses and trojans like Win32:Delf-MZG in multiple programs -- probably you don't have to worry. This is happening to everybody who was pushed the new iAVS update for Avast.

The false positive error occurs since Win32:Delf-MZG uses the same script coding as most regular programs such as virus scanners.
In other words Avast is detecting viruses and trojans that are not really there. If you allow it to remove them or move them in the chest, it will make your applications stop working. This is the worst thing you can do because that means you will have to reinstall all of the "infected" programs afterward.


The solution is to wait for another avast! update or just disable Avast (right click on Avast in your system tray and stop it) and download another free anti-virus program until they get this straightened out.

You may try AVG or Avira Antivir. Also make sure that you turn off Avast first, because if you do not, you won't be able to download any new programs.

Important update: a new update (version: 091203-1) that offers a fix has been pushed out. Currently Avast is not reporting any false positives. Manual update of iAVS is highly recommended.

  1. I have the same problem! The only solution for the moment is to desactivate the standard shield or switch to another antivirus program.

  3. I also have the same issue. Cannot update or start my Spy Sweeper. Also found 21 infected files. I deleted them, hope I didn't screw up too badly.

  4. Don't empty your trash if you deleted them. If you deleted permanently you will have to reinstall or do a system restore...

  5. Just click NO ACTION and wait for an update from Avast. Hopefully it will be soon. I have many programs detected as the virus that are not viruses.

  7. I almost deleted my FlStudio 9 Music Program and many many others as a result of this sudden and FALSE warning. I thought that my PC was being overrun with every virus known to man! Somebody managed to hack Avast's server and screwed up the virus definitions. DO NOT DELETE YOUR PROGRAMS!

    /end rant.

  8. Anyone figure out how to revert database back one level?

    I see stuff in
    C:\Program Files\Alwil Software\Avast4\Setup\

    Likely:
    vps-9120300.vpu

    But, no previous *.vpu to restore from back-up

  9. ok, I got the problem last night, turned off standard scanner. received new virus pattern this morning. All is now quiet!
    If you quarantined, restore any "falsies" from virus chest!

  10. Tivo Desktop doesn't work after installing the new avast. Can't restore either. We installed it because the new AVG killed the ReplayTV download program!
