I have much the same issue, this folder keeps filling up whenever the security centre is running and choking my OS drive. I'm personally not keen to move the %ALLUSERSPROFILE% folder itself, just the location KSC uses to retain temporary copies.
Can you provide more detailed instructions on how to move these folders to another partition permanently? This problem has been raised several times on these forums and to my knowledge no solution has been forthcoming from Kaspersky, I would love to be proved wrong if a fix exists.
Alternatively can Kaspersky provide a patch to allow these updates to be redirected?
