If you had another user account then you could log into that alternate account and get rid of it. I don't know if you'd want to go through the trouble of creating a new user account (which you could delete immediately afterwards) just to get rid of this file, but if you do, here's how you would do it:
Log into the other account. In windows explorer navigate to C:\Users\Tommo\Desktop. Click on Organize then choose Folder and search options and click the View tab near the top. Under advanced settings, go to Hidden files and folders. Make sure that "Show hidden files,folders and drives" is checked.
Now move all of the files in the Desktop folder, except the "dayna" file, to another location. Now open Command Prompt and go to C:\Users\Tommo and enter this command that will delete the desktop folder: RD /S Desktop Then create a new Desktop folder in C:\Users\Tommo and move all of your files back into it.
Finally, log out and then log into your regular user account to verify that the file is gone and all of your other desktop icons are there. If it is, you can safely delete the new account that you created if you want to.
I know that this is a lot of trouble to go through just to get rid of one file, but it should do the trick.
