Faulting App 'explorer.exe', Faulting Module 'ntdll.dll'

There is a client who has some issues on his system, when trying to browse my computer, either by way of double click or right click the shell crashes with an application error. The computer is running on Windows XP SP2 and office 2003. It is updated to the latest patches. I did a scan for malware and removed some corrupted software as well. This computer has got Norton SystemWorks with GoBack and I think that it might have something to do with the issue. It is actually limiting me from deleting explorer.exe, as it comes up "access denied". Can anyone please help.

Can you check the Event Viewer for some error reports in the System and Application logs for the last boot and post the results. You can access the Event Viewer by choosing Start > Administrative Tools > and Event Viewer. Check the below link for more information:

Thanks, after going in the Event Viewer I found some reports in System log, which I have pasted below:
