Summary

Etap is a cross-platform virus, infecting Windows executables and Linux ELF Executables. It was found in February 2002.

This virus has never been widespread. It is difficult to detect reliably as it is encrypted with variable encryption and it uses entry-point obfuscation techniques, which easily create false alarm problems for anti-virus programs.

FALSE ALARM INFORMATION

F-Secure Anti-Virus definition update shipped late on December 17th 2002 contained a false alarm for the Etap virus.

This update will result in F-Secure Anti-Virus erronuously detecting the "Win32.Etap" virus in several clean files.

Examples of such clean files include:

RSE.DLL in Autodesk Inventor 6 SP1

VISLIB32.DLL from Microsoft Visio

S32GUIL.DLL from Norton Utilities

LXAKWEB.EXE from Lexmark drivers

3DADVSIM.DLL from AlphaCAM

3DVERIFY.DLL from AlphaCAM

NETWORKSENSOR.DLL from ISS Network Sensor

IPANEL.EXE from FORAN

You can safely ignore Etap warning on these files.

A fix for this false alarm was shipped on Wednesday December 18th, 2002 through normal update channels.




The false alarm is fixed with the following F-Secure Anti-Virus update:
