Viruses aren't able to survive on inanimate objects, they need a host, eg animals or plants, depending on the virus. They can only infect you by transfer of bodily fluids. You cannot (at the moment) kill any viruses. You can only slow down their processes or be immune before coming into contact with one. Or have some sort of tolerance to them. Like the common cold virus, we can cope with it if our immune system is working properly but you can't cure it. Eskimos would die from the cold believe it or not. The freezer idea would only kill certain bacteria. P.s Viruses are completely different from bacteria.
