Cleary,
Looks like you have some sort of Trojan there.
Regarding HKEY_LOCAL_MACHINE\Software\JackassArswareOrg\Start Right\Run and is shown as:
File c:\program files\slysoft\anydvd\anydvd exe.doe

You must delete that key and when deleted check and make sure the slysoft executable file looks like this
File c:\program files\slysoft\anydvd\anydvd.exe

You say the registry entry is stubborn to remove, it’s probably because of permissions are prohibiting it’s removal. Use Regedit and navigate to the key, in Start-Run box type in regedit and go to the key.
First try right clicking on the key and chose delete, it may not work.
If not, right click on the key and select permissions. All three boxes should be checked under allow. Sometimes the third box special permissions will be grayed out and you must correct that.
If your user name is not there, hit the add button and type in your user name, once you’ve done that under group or user names highlight your name, then check all the boxes. This will enable you to delete those stubborn keys.
If you are not authorized to do it and don’t have full administrative privileges, have the person who has full administrative privileges do it.

Good Luck
