Could be a virus, but since you say it's not...
I'd check the event log (run "eventvwr") as step one.  Look for any
error messages, and I'd pay particular attention to messages about bad
sectors, NTFS errors and the likes.

(And then I'd probably store the files in a repository, using
something like TortoiseSVN.  Makes it real easy to see whether files
are missing or not, plus you'd have a sort-of backup.  Easy to store
the repository on a samba server, too.)

Did you mean"of this" and "open one folder"?

Open  Access: Read

Looks rather harmless, since a) it's opening for read access only, and
b) the stream is non-existent.

That said, I've never seen my explorer.exe do the above, so there's a
reasonable chance that it's an in-process COM object that is doing

For example, since you're browsing a folder (or so I'm guessing), it
could be a column handler COM object.  Try nuking all of them (backup
first) from HKEY_CLASSES_ROOT\Folder\shellex\ColumnHandlers and see if
the above goes away.

(If you're at all interested in making it go away, heh, seeing as it
seems harmless.)
