I use McCafee Security as a part of my Internet service by AOL. Applicable softwares are supposed to be down loaded automatically into one desktop in Windows 7 and another one in Windows XP. Recently software updating in the XP stopped. Websites of AOL and McAfee don't help. Any clues?
Some malware disables automatic updating, so right-click the McAfee icon in the system tray and select Check for Updates and then run a Quick or Full Scan.
Also you can manually update the files
This might enable detection or at least shock the updater into working if the update button option fails.
That has been a problem to be before when I was in Windows XP. This is why I suddenly switched to Windows Vista as I can't find any solution for it, but I will still get back to Windows XP once I have found any fix for this problem.
