Today, on one of my two WinXP computers, I have a red security alert shield
in the system tray. I checked Microsoft Update, and there are no updates
being offered. Is this a "legitimate" red shield rather than malware
masquerading as a Microsoft notice?
If it's legit, is it likely to be the Fix it for Security Advisory 2749920
that I read about at the Microsoft Security Response Center (by way of
Google Reader):
http://support.microsoft.com/kb/2794220
Should I click on the Fix it button "Microsoft Fix it 50971"? Should I open
the Security Center from the red shield instead?
I'm confused about why I have the shield on only one computer, when both of
them are running IE8. The only difference I know of between the two
computers is that the one with the shield is using WinXP Pro and the other
one WinXP Home. I've never had the red shield before and want to make sure I
do the right thing...especially since Microsoft normally presents its fixes
with a yellow shield and an update at the Update website.
Thank you!
