This virus is multi-platform and polymorphic infector affecting both DOS and Win32 files, it was named after the text strings in its code:
 [Win32.Libertine v1.07b]
 Copyright 1998-xxxx by <NeverLoved>

The virus can be found in three different forms:
- infected Win32 PE files
- infected DOS COM files
- Win32 PE dropper (31672 bytes pure virus code)

While infecting both Win32 and DOS files the virus writes its complete 32Kb code to the end of files and modifies file headers to pass control to the virus routine. The addresses of entry routines are different in all three cases of infection. The virus in both infected Win32 and DOS programs when takes control searches for Win32 dropper (the C:\MYLENE.EXE file), executes it and returns control to the host program. If there are no dropper in root directory on the C: drive, the virus first creates and then executes it.
