recent XP security updates

Yesterday, my computer automatically downloaded security
updates for Windows XP. I installed them, before turning
my computer off for the day. This morning, while I was
logging on to AOL, I got the following message -

The America Online software is no longer
running because amcgehee signed into this
computer and used America Online.

I am the only one who uses this computer. I'm signed on
under amcgehee, because this is my computer and there are
no other users.

I've restarted the computer twice, but still get the same
message. I am able to log on to AOL,but it is very
annoying to have this message.

What did you guys do to my computer?

Nevermind - After rebooting several times, the message is
no longer appearing. Perhaps this was McAfee's fault.
They automatically updated my antivirus software this
morning.
