Lager.DP is a mass mailing worm that drops a copy of Small.DAM.


Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

Technical Details

Lager.DP arrives on the system as an attachment to spam emails.

When executed, Lager.DP drops a copy of itself named "alsys.exe" in the Windows system directory.

It also drops several files in various locations on the system using a random eight character filename.

  • [8 random characters].t

In addition to this, it drops and executes a randomly named copy of Small.DAM in the current directory.

It also adds the following registry entries to enable its automatic execution upon system Startup:

  • HKCU\Software\Microsoft\Windows\CurrentVersion\RunAgent = "%sysdir%\alsys.exe"
  • HKLM\Software\Microsoft\Windows\CurrentVersion\RunAgent = "%sysdir%\alsys.exe"


Lager.DP propagates by mailing itself to several email addresses gathered from the affected system.
