Situation:

Connected a FAT32 drive (D:) to a system with an NTFS Win-XP pro drive
(C:)

XP booted and at some point created a \system volume information\
directory on the D drive. While in XP, I can browse, delete, and move
files within the D:\system volume information\ tree at will. I can't
do any of those things with the C:\system volume information\ folder.

You can point Norton to the D:\system volume information\ folder and
tell it to scan that folder, and it will go through the motions, but
it will report 0 (zero) files scanned (there are 2 files there - a
.log file and the .SCR file in question).

The cleaner WILL scan the D:\system volume information\ tree and
apparently Norton will intercept all files accessed from this tree and
scan it before The Cleaner gets it.

Using native system functions (my_computer, explorer) can you browse
your C:\system volume information\ folder while running XP?

Will Norton Scan "?:\system volume information\" during a manual or
scheduled scan (it appears the answer is no) or does virus discovery
in that folder depend on some other program accessing files in that
folder (it appears the answer is yes).

Clearly the permission structure is different. Again, if a FAT32
drive (D:) is connected to a computer running XP (C:) then you _can_
browse, copy, and delete files within the D:\system volume
information\ folder. You can't do the same for the C:\system volume
information\.

I don't have an XP system in front of me currently, so I don't know
the answer to this: Tell Norton to scan your C:\system volume
information\ and look at the report. How many files did it say it
scanned? Zero?
