This update ( KB2286198 ) blue-screen crashed two fully updated Vista Home Premium 32-bit SP2 computers, both running NOD32 version 18.104.22.168. Other PCs, same OS with Norton 2010 updated fine. Both PCs self-rebooted after the crash. One successfully installed the update, the other shows a status of Pending. On the Pending PC, if I Check-for-Updates again, it shows the same update needs to be installed.
