During an application update, the McAfee update icon is displayed in the System Tray. If the whirling icon does not disappear after a few minutes, the update may have stopped responding.
Manually Stop the update and restart the computer
1. Press Ctrl+Alt+Del to open the Windows Task Manager.
2. Click Task Manager.
3. Click the Processes tab, then right-click mcupdui.exe and select End Process.
4. Click Yes in the warning dialog box.
5. Close Task Manager.
6. Restart your computer.
The update session will restart after your computer restarts. The animated update icon will appear in the system tray while the updates install.
Ctrl-alt-del is working with XP home?
Thank's for all.
Glad that you are ok now, do report back if you have any issues
