The virus? It is called by a script. When deleted, get a black screen. However, functionality is not zero. Ctrl-Alt-Del brings up task manager and you can run programs by typing in their executable name, e.g. "firefox", or "iexplore", etc. All works well. typying in "explorer" brings up the desktop and all looks OK, until one hunts around, and it is clearly a fake.

If the process 'explorer.exe' is stopped via WinTaskMngr, the desktop disappears, but is easily restored by simply going to the Appl tab of WinTaskMngr, if already open, and click on New Task and enter 'explorer.exe.'

Very, Very, Important system.

explorer.exe is a critical component of Windows. Ending the process will cause the desktop, taskbar and any open windows associated with it to disappear, leaving the computer almost non-functional until it is restarted.
   
Explorer.exe is located in the Windows directory of your boot disk and it is the file manager, taskbar and start menu of any Windows version in since Windows 95. If explorer.exe crashes, you can re-open it through Task Manager.

Best practices for resolving explorer issues

A clean and tidy computer is the key requirement for avoiding problems with explorer. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the explorer.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
