Microsoft Security Essentials Stops Scanning

When I use Microsoft Security Essentials Quick Scan, it works fine.  However, lately when I use the full scan, it stops scanning soon after it starts.  I have removed any other security software that was installed at one time using Revo Uninstaller.  

Any ideas why the scan stops?

This is a stand alone laptop using Windows7.

I found that several people have this problem.  In particular, the scan stops when it tries to analyze c:\windows\system32\codeintegrity\driver.stl.  I don't know why nor do I know how to fix this problem, but the work around is to put the file path and name in MSE Settings> Exclude files and locations. Now the scan will look at every file but the one excluded.  
It works.
Try running the scan in safe mode with neworking. Check whether it stops at the same file. If it doesnt then problem might be caused by some software running at startup.

It wasn't easy to remove, but that was the answer.
