-------

        Sophos seems to truncate the paths for the sake of the report, but
they are long (the second one exceeding 256 characters even when using the
'~' notation.
        Those eicar files are still there from when I originally tested
(with 3.53 [January's update]). Obviously explorer was unable to delete
them.

        The platform tested was Win2000 SP2 (before and after the recent
security roll-up patch). I have not tried NT4.

        Regards,

Dave
