Win XP Home SP2 security center issue

Windows XP Home SP2
When the computer boots, Windows XP Security Center tells me that Norton AV
is turned off.

Owner had Norton 2004, which had expired. I uninstalled it using Add /
Remove programs and Norton's SymRT [ removal tool ].

Computer had malware, which I removed.

Where is Win XP looking for, & finding that NAV 2004 was installed on the
computer?

It is not in the Sys Config.

There are no Norton / Symantec services running.

Where is the registry is Win finding the past existence of Norton 2004?

NAV 2004 was uninstalled using Symantec's removal tool & Windows Cleanup
Utility.

Sincerely,
WC
