Norton Internet Security 2005 conflict with Windows XP?

I received my new Dell Dimension 4700 late Friday. Dell installed Window XP Home Edition (version 5.1.2600) and Norton Internet Security 2005. At the end of Norton Internet Security’s initial set up routine, Norton prompted me to scan my computer. When I attempted to launch the scan, I received an error message, Norton AntiVirus Scanner Module has encountered a problem and needs to close. The error message appeared to be generated by Windows: it was in a Windows box and no Norton error code was given. The computer requested permission to send an error message to Microsoft. Among the information included in the error message was AppName: navw37.exe, AppVer: 11.5.0.44, ModName: msvcr70.dll, ModVer: 7.0.9466.0.

I spent Friday evening and most of Saturday on the telephone with Dell and Norton Technical Support. During the course of those calls, I uninstalled and reinstalled Norton Internet Security six times. Reinstalling Norton Internet Security did not resolve the problem. In fact, it made it worse. After the first reinstall, I was no longer able to install Live Updates to Norton AntiVirus, although I was able to download them and install all other Live Updates, including Live Updates to Norton AntiVirus definitions. The error message for this problem included The files below could not be updated by Live Update. File: C:\PROGRA~1\NORTON~1\scanmgr.dl^337520 Bytes 3/3/2005 0:15:28v11.5.0.42 C:\PROGRA~1\NORTON~1\navcomui.dl^1025648 Bytes 3/3/2005 0:15:02v.11.5.0.42. After running Live Update twice, it also included the Norton error code LU1806; however, Symantec fixes for error code LU1806 did not work.

Late yesterday at the direction of Dell Support, I restored my computer to the factory state and reran the initial set up routine. As a result, the Live Update problem is now fixed. However, I was again unable to launch a scan at the end of Norton initial set up routine and cannot launch one from Norton Internet Security now that it is set up. Every time I try, I receive the Norton AntiVirus Scanner Module has encountered a problem and needs to close error message.

Norton believes that the problem is a conflict between Norton Internet Security, probably the Norton AntiVirus component, and Windows, probably a security or Internet security component. Norton bases its belief on the fact that I was able to run a scan in the safe mode, albeit with after my computer told me that it could not run a scan in the safe mode. I suspect Norton is right because the error report that my computer sends to Microsoft includes a document entitled C:\DOCUMEN1\MYFIRSTNAME~1\LOCALS~1\Temp\6740_appcompat.txt and appcompat sounds a lot like application compatibility to me.

Has anyone encountered the inability to launch a scan problem? If so, how did you resolve it?
