After scanning my system (XP SP 3) with my Internet Security Software (Kaspersky) PM (4.5.3.2 beta) was detected as "High Danger" because of the file zlib1.dll. After updating to
zlib1.2.3 everything is o.k. I´m not sure whether this was really "High Danger" but it might be of some interest for Kirk and the other users.
