Help! How do I clean my file? It has been infected with a virus.

I need help! How do I clean my file, which has been infected with a virus?

I need to use the file but I can't access it ever since Norton Internet Security 2010 detected a virus in it and kept it somewhere.
Is there a way for me to use Norton Inter Security 2010 to clean the file by separating the virus from the file, so that I can restore the file without any worries?

The virus is a Trojan.Maliframe!html
