This really depends on the file. If you have a useless malicious file, such as a infected downloaded file, that has no system importance, then yes, it would be recommended to delete that file. However if it is a infected system file or other important file DON'T delete it. Leave it in the virus chest and see if it is possible to repair it.
Heal function tries to remove the virus from the infected file. If the file is really infected so it may work or not (because it is difficult or it is not really infected), but if it is not then it will not work. If AVG manages to remove the virus, the file is free and not infected anymore, if not then you should move it to the vault or delete it.
