Melder is a harmless nonmemory resident parasitic Win32 virus. The virus itself is a Windows PE EXE file, written in Delphi. The virus size is about 46KB.
The Melder virus infects .EXE files in the Kazaa file sharing network download directory. In case Kazaa is not installed, the virus fails to infect the computer. While infecting the virus writes itself to the beginning of the file (the original file body is moved down before infecting).
The virus also copies itself to two files in the Windows directory and the Temp subdirectory:
in Windows directory: Melda.Scr in WindowsTemp directory: KaynakDosya.exe
The virus contains the text string:
