    - NEurOTiCDEatH virus type 5 link virus
        Name NOT understandable, but adopted
           In the decoded link part you can read:
           8002ee58 32c04e75 00000002 00005b4d ... X2.Nu ...... [M
           74675f33 415d0000 1bdf0000 00096100 tg_3A] ........ a.
        Compared to Type 3, I don't have a Neuro .. text
        File extension: larger # 6000 bytes and smaller # 8000 bytes
            (so it was with my tests)
        Not reset-proof
        Processor better than 68000
        Not all kickstart versions
        Bent vectors: LoadSeg NewLoadSeg DoIo
        The virus part is to be activated from Dec. 28, 96.

      Memory anchoring:
           - Test whether already in memory e.g. debug Data
           - Test whether antivirus prg.e is active (e.g. Xtruder)
           - Loadseg NewLoadSeg and DoIo are bent
           - Tests later loaded file names for "v" or "V".
      Link operation:
           - With LoadSeg and NewLoadSeg
           - Medium validated
           - File executable ($ 3F3)
           - CodeHunk is found ($ 3E9)
           - Overflows $ 3F1-Hunks
           - File length larger # 32768
           - File smaller # 286720
           - Searching for bcc ($ 6v00wxyz) in the 1st Hunks,
             jsr xy ($ 4EBAwxyz) or jsr -xy (a6) ($ 4EAEwxyz)
           - This LW is replaced by bsr virus ($ 6100wxyz)
           - the part is always re-encoded with $ DFF007

           - NO

           - Write garbage with DoIo
           - Destroy Random Block based on $ DFF006
           - Random block always bigger # 63 ($ 7E00)
           - VT CANNOT recognize a block like this
           - This block cannot be saved
        VT tries to reset the vectors in memory.
        VT cannot repair all files.
        If there are errors in the file, send me
        such files please.
