Microsoft Security Alerts
I have a Dell desktop computer, Windows XP sp3. I have my Windows updates to notify me, then I download, install. I did that on Sep 26th. When I did the restart, I got a security alert when it came back on and said I didn't have any virus protection. I use Microsoft Essentials. The icon loaded about then and said I was protected. I x'ed out the alert, ran anti-virus, SAS, and Malwarebytes. All okay.
A few days later, I shut the pc down. It came back up the same way. I was able to x out the window and all was well again. Next time, I got NO alert. Today I downloaded/installed the windows current updates, restarted, icon again says I'm protected but I can't get rid of the Alert icon. It still says I have no antivirus.
Tell me if you need more info. I just don't know what to do next.
