Explorer.exe does not Load

Hi everyone,

 

I am having a really big problem which is that my Explorer.exe is not running at the startup.

 

I have tried running it with the task manager by using Run new task and selecting the Exporer.exe in the WINDOWS folder but it still wont open.

 

I had a some viruses on my computer and this is why I installed the trial of Norton Internet Security 2010.  The Explorer.exe was running fine until I install Norton and then restat.  Once restarted Explorer stoped loading so I uninstalled Norton but the problem is still there.

 

Please could anyone help me !
