    Strange that Symantec managed to make their product so much worse
    during upgrades; I'm running Engine 5.00.01b, Viruse files 14.01.2000;
    results are significantly better:
    
    1) There is no exclusion for \RECYCLED directory, neither hidden nor
    in the GUI. Exploit does not work, virus is detected.
    
    2) The Excludes for EXCEL.EXE, WINWORD.EXE, POWERPNT.EXE and
    MSACCESS.EXE only turn off the check for writes to program files.
    Renaming the EICON.COM file from the exploit to excel.exe does not
    prevent NAV from finding it.
    
    3) All Exclusions are visible using the GUI Interface.
