TA,
With the very greatest of respect [translation: nah, nah, nah, nah, nah! ;-) ]), I think it is
you who may not have read around the subject.
Go to that
link that I included and scroll down through the comments.
All will be revealed.
Kaspersky is not to blame. All it has done is use a feature that is supposed to be an integral part of NTFS but which would appear to be broken in Vista.
Oh and if you do read through those comments, you'll notice that Microsoft has a
hotfix for the problem - something it wouldn't have bothered creating if the fault lay solely with Kaspersky.
Currently, though, by my reading of what Microsoft says, the hotfix would appear to be a bit like Vista itself, ie work in progress.
