Cant update 10.6 to either .3, .4 or …

goClimb found the solution:

Figured it out (or fluked it and missed something completely :o)

Problem Summary: 21″ iMac couldn’t run software update (any version of last three), got as far as moving items and hung. Reboot would then hang and had to restore to backup. NO ISSUES WITH MAX FILES. Note: Also had previously uninstalled trend micro smart surfing and then sophos anti virus. Despite being removed weeks ago Trend had left behind (I believe) two processes: 1) iCore plug in manager and 2) iCoreServices. Also note that iMac had been set up using set up assistant and I have deleted a redundant non-admin user account.

Solution: Repaired permissions and disk, rebooted in safe mode, used Terminal to kill the iCorePluginMgr and iCoreService processes and then ran the update (10.6.5) from a local downloaded disk image.

Would be interested if anyone knows how to permanently kill these processes?

Thanks, at last :o)
