Hi malware fighters,
"Don't panic. Do a three-fingered salute (Ctrl-Alt-Del) and choose Task Manager. Click the Application tab and choose [New task...]. This is a generally handy way of getting back into your PC if the Explorer.exe process ever dies or won't start – for example, as a result of malware infection, or as a side-effect of ill-advised experiments after reading up about black screens of death.
Run the program Explorer.exe. This gets you back into your desktop, icons, menus and so forth. (If you launch a second or subsequent copy of Explorer.exe, you will get the Windows Explorer file manager rather than a second copy of your desktop.)"
This trick has been applied by me many times.
When Explorer.exe crashes, you will have no desktop. Just restart the process and there you are!
