W32.NewApt.worm:

Infection:
The worm is sighted 'in the wild' in states of europe, america and asia. It diffuses (naturally) with emails in an infected attachment. The known filenames of the attchment are:

PANTHER.EXE, FARTER.EXE, GADGET.EXE, BOSS.EXE, IRNIGANT.EXE, MONICA.EXE, CASPER.EXE, SADDAM.EXE, FBORFW.EXE, PARTY.EXE, CUPID2.EXE, HOG.EXE, GOAL1.EXE, BBOY.EXE, PIRATE.EXE, BABY.EXE, VIDEO.EXE, GOAL.EXE, COPIER.EXE, THEOBBQ.EXE, COOLER1.EXE, PANTHR.EXE, COOLER3.EXE, CHESTBURST.EXE, G-ZILLA.EXE.

The subject of the infection mail is "Just for your eyes" or "Re: Just for your eyes". The mail may content text or not. If the attached EXE-File is executed, the worm will get control to your PC.

Payload:
If the worm is executed, it copies itself into the Windows-directory using its current name mentioned above. Then it registrates its copy in the registry editor under the key
SOFTWARE\Microsoft\Windows\CurrentVersion\Run
with different entries (respectively to the filename) and the value "C:\WIN\EXE-Filename /x". This entry takes care for the execution of the virus at every systemstart. After this the worm shows the following message on the screen:

The dynamic link library giface.dll could not be found in specified path
D:\SAMPLES;C:\WINDOWS\SYSTEM;C:\WINDOWS;C:\WINDOWS\COMMAND

which is intended to mask its existence and lead to a restart.
Further it creates and initializes the following registry keys under  HKEY_CURRENT_USER\Software\Microsoft\Windows:
  itn = , cat = , cd = , lk= , lms= , mda= , mde= .
The wormn registrates itself as a service and so it is executed unvisible at every start. Here it searches on every harddisk drive for internet-files (MS Mail, Outlook Express, Netscape Navigator etc.) and opens these files and sends itself to the found emailadresses.

Removal:
To remove the virus from your PC,  you must delete the 'Run'-entry in the registry and thereafter remove the infected files. Norton Anti Virus offers an update. Download it: Download Virus Definition Updates

Remarks:
The worm deletes itself at June, the 12th in 2000 by removing the 'Run'-value from the registry, After this it will not be executed when you start the computer. If the date-value is set to a value before 06/12/2000, an infected EXE-file can restart an infection on your PC.
