Some of the experts here may have better ideas, but until then I would visit the Windows Update site, let it scan your computer and then choose Custom install.
Then if Windows Updates lists those two KB's, you can choose to "hide" those updates. That should stop your computer showing the icon.
I recently changed ISPs as part of a reformat and reinstall of Windows XP Home. When I went to Windows Update to download all the critical and security updates, all went well until I got to the security updates that reference MS KB920683 and KB914388.
When I install them, upon reboot, I get the error dialog "Generic Win32 Host Processes has encountered a problem and needs to close." After that, I cannot get online. I can "fix" the problem by either using System Restore or System File Checker (SFC /SCANNOW), but then the little yellow shield pops up in the system tray telling me that those updates need to be installed. Interestingly enough, when I open Add/Remove Programs, both updates are shown as installed.
