Windows 7: Desktop.ini on my desktop

HI: A couple of days ago my computer would not shut down. I tried ctrl-alt-del, alt+F4 and window key-release-rt arrow-enter and it didn't help. At a last resort had to press the power button on computer and it did finally shut down.
It started up into safe mode and was waiting for an option, so I highlighted normal or regular start. The desktop appeared but with two icons of desktop.ini. When opened up in notepad, this is what they read:

[.ShellClassInfo]
LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21799
[LocalizedFileNames]
Norton Internet Security.lnk=@C:\PROGRA~2\NORTON~2\Branding\muis.dll,-102

[.ShellClassInfo]
LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21769
IconResource=%SystemRoot%\system32\imageres.dll,-183
[LocalizedFileNames]
Internet Explorer (64-bit).lnk=@%windir%\System32\ie4uinit.exe,-735
Internet Explorer (No Add-ons).lnk=@%windir%\System32\ie4uinit.exe,-737
Windows Media Player.lnk=@%SystemRoot%\system32\unregmp2.exe,-4

Scanned both desktop.ini icons on desktop with Avast, MBAM pro and SAS and all were OK.
I don't even have Norton installed on my PC. (where would that have come from?)
Could you please tell me what all this means and why because of a bad shutdown this appeared? Can they safely be deleted?
Is there a recommended way to force a shutdown?
Many thanks for your help.

Not anything serious, dont worry. It is not a virus or anything.

Go to control panel folder options, and make it sure that the protected OS files are hidden, at first ! All the hidden files are also not to be shown.

Hidden Files and Folders - Show or Hide

There's nothing wrong with showing hidden or system files if you know what you're doing. Those are the first things I "fix" on a new Windows installation. Despite showing hidden/system files, I normally don't see desktop.ini on my desktop. It recently appeared for me when I updated NVIDIA drivers, but you can just delete it.
