I have recently run into a problem.
Every time I exit Windows Explorer, a box pops up and tells me that Windows Explorer needs to close. I click Continue, then another box pops up, says almost the same thing, so I click Continue, and my entire desktop disappears, all programs shut down, then my desktop comes back. I have now lost everything I was working on.
However. If I click on Continue then quickly click on any open window before it shuts down the desktop, I keep all programs running, and I do not lose any work(s) in progress.
I searched for what might be causing this problem at the Windows update, and the closest one talked about a Nimda virus that can cause this.
My dad is a software programmer, and he went to work on it, but came up empty handed. I downloaded a FixNimda.exe file from Symantec, but it said it could not find the Nimda either version A or B. I do see the csrss.exe file running in my process list, but I can not stop it, since Windows says it is a critical system process.
