      File extension: # 1060 bytes
      Not reset-proof
      Bent vectors: LoadSeg NewLoadSeg
      Memory anchoring:
           - test if already in memory ($ 2F01)
           - Loadseg and NewloadSeg are bent
           - Tests later loaded file names for "v" or "V".
             It is therefore useful to have your antivirus program for the
             private !!!! Rename use, otherwise you could
             think your system is clean because the part at "v"
             or "V" removed from memory.
      Link operation:
           - with LoadSeg and NewLoadSeg
           - File not yet contaminated (date)
             So if you copy a contaminated file and the file
             Do not take the date with you, it can lead to multiple contamination
           - Medium validated
           - 4 blocks free
           - File executable ($ 3F3)
           - CodeHunk is found ($ 3E9)
           - File larger than # 2120 bytes
           - File less than # 282286 bytes
           - 1st hunk smaller $ 1fff x 4 = # 32764 bytes
           - The search is in the 1st Hunks in a range of
             # 32736 ($ 3ff0 x 2) to bcc ($ 6v00wxyz), jsr xy ($ 4EBAwxyz)
             or jsr -xy (a6) ($ 4EAE wxyz)
           - This LW is caused by bsr virus ($ 6100wxyz)
           - the part is always re-encoded with $ DFF007
             If the value $ AA is reached in D7, one should
             "Floppy music" can be triggered. Your disk drive will
             So take damage through end stops if you don't
             react fast.

      Removal: Kickstart 1.2 & 1.3 : VT-Schutz v3.17
