This is usually a Windows update error since Security Essentials uses Windows update.

This problem is not hard to troubleshoot if it is caused due to a corrupted windows update file.

1. Open command prompt and then run the following command,
net stop WuAuServ
2. Open Run dialog and enter "%windir%" (or navigate to C:\Windows directory in Windows 7).
3. Find a folder named SoftwareDistribution. Rename it to something else e.g.- SoftwareDistribution.old.
4. Open command prompt again and then run the following command,
net start WuAuServ

Now this should fix the problem. Try updating now and see if everything goes ok.
