Q: Why does the Windows Security Center say that the status of my
Norton
security product is "unknown."

A: Your Norton security products contain tamper protection features
that
prevent malicious code from determining their status. This tamper
protection
also prevents the Windows Security Center from determining the status
of your
Norton security products.

I'm interested in knowing how the update status of antivirus or other
security apps could possibly be of use to malicious code. In any case,
as I read it, this is not the issue being discussed in the article


Symantec has released an update which adds compatibility to the
Windows
Security Center so that it may report the status of your Symantec
security
software. This update is included in Norton 2005 Security Products and
is
available by LiveUpdate for Norton 2002/2003/2004 Security Products.
The
update will install on Windows XP, but will not take effect unless you
have
the Windows Security Center installed.


Which doesn't in the least explain why it needs to disable Windows
Security Center in order to install (if, in fact, it does so. I only
have the article to go by.)
