Weird file question.

[SuSu]

Hi everybody !  
I have this weird file that kinda recopies itself or something like that. When you doubleclick it, it asks what do you want to open this with, I am very hesitant to open it with DOS being worried it might be some kind of weird virus, even tho all virus scans come up clean. The properties of this file are this.
Type:  File
Location: C:Windows\Desktop    also recopied itself into Windows folder after moving it from Windows to desktop

MS-DOS name:  ~

It is almost impossible to search for this ~ symbol anywhere since it is just one character long and after searching many DOS pages I cant find anything about it.

Any knowledge on a ~ file would be greatly appreciated!

                                        Thanks
