The shell unexpectedly stopped, the reason and solution for Explorer.exe being restarted

These two days were tossed by the server, and the program in the event viewer kept reporting "The shell program stopped unexpectedly, Explorer.exe was restarted" error, and then the explorer was closed. Restarted, and then there was an error that IE was closed.

began to suspect a hardware conflict, the results of all the machine's hardware is changed again, the next table colleague's machine apart a mess, ultimately failed to solve.

Later, I searched the Internet and found that there was a lot of discussion, but I didn’t understand it. But also want to summarize:

1, first check to see if there is a "trojan" virus — — if not. PS: It was later found to be less likely to be a problem. 2, check for some special things in the registry (including ——HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer\\Run COM Service = C :\\WINDOWS\\msagent\\gditpxr.pif

and {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3}), although I don't quite understand it, but the former is not in my machine, and the latter is from the relevant key name. Obviously related to Adobe Acrobat, I just installed Adobe Acrobat reader 5 and Adobe Acrobat perfonal 7.0, so I uninstalled the 7.0 product first, and the reader did not move, and then check the registry, there is only one or two places that are irrelevant. The place has been retained, and I will ignore it for the time being.

So far, the machine is not malfunctioning, because it is Adobe's relationship. If it is not recommended to check if you have recently installed and updated some software.
