try to re install the norton software and then let the program run live update at end. If this still doesnt work go get another kind of antivirus software. -- wolfy
I used Live Update tonight and, for the first time ever, it told me that the update for virus definitions had failed. I clicked on the error code and the Symantec website advised me to download the Symantec Automated Support Assistant which then updated my Live Update file from LuComServer_2_6.EXE to LuComServer_3_0.EXE.
I then rebooted, as instructed, and tried running Live Update again. Once again it failed but the new error code sent me here: http://service1.symantec.com/support/sharedtech.nsf/docid/
which instructed me on how to replace damaged Live Update files. I followed the instructions but was unable to delete ALUSchedulerSvc.exe because Windows told me it was in use! I followed everything else except uninstalling the whole works and reinstalling.
I'm hopping mad right now because Symantec is the one that forced me to update this file and then they say their update is damaged!!
