I believe Chris may be referring to Malware under Windows Security Center.
It shows Windows Defender as being turned off and does not let you turn it
on. Windows Defender is loaded at start up but not recognized in the
Security Center. Anyone else have this issue?
I had issues with the Security Centre, mainly its very annoying and
unecessary for experienced users to have this service running and
whining in the system tray. I can see the point for non savvy users
but I hate the thing.
Used this fix to remove it altogether

The tweaks there work for 5484 also.

Get Rid of The Nagging Windows Security Center Icon
The Windows Security Center has been one of the biggest annoyances
since the inception of the idea with Windows XP Service Pack 2. Now
with Windows Vista™ it is new, improved, and even more annoying than
ever before! Untill now, you could not get rid of the icon from your
tray.
Here's how to nuke Security Center off your system. This has been
tested and there are no adverse effects from doing this.
1. Go to Start --> Run and type "cmd" without the quotes.
2. Type "cd\" followed by "cd windows\system32".
3. Now run the following commands:
* takeown /f wscapi.dll
* takeown /f wscsvc.dll
* takeown /f wscui.cpl
4. Now you have ownership of the files. Go into the system32
directory in explorer and right click each file, go to the security
tab and add an entry for everyone and give them full access
permissions.
5. Disable the Security Center Service via services.msc if you have
not already done so.
6. In the system32 folder rename the three mentioned dll's (change
their file extension to .bak).
7. To get rid of the Security Center service from services.msc drop
to a command prompt and type the following:
* "REG DELETE HKLM\SYSTEM\CURRENTCONTROLSET\SERVICES\WSCSVC
/F", hit enter and reboot.
8. Enjoy no more nagging or icon in your system tray!
