It lives in the soil of hundred year old graveyards.
First viruses are not alive. Technically because viruses do not reproduce by sexual or asexual means they are not alive. Viruses reproduce by hijacking the internal machinery of a host cell.
Second very few viruses remain viable (transmittable) after being transferred to an inanimate object for more than a few days (the cold virus is very durable and is viable for up to a week). They are destroyed by ultra-violet radiation, are eaten by bacteria or simply dry out.
Even opening the grave of a victim you would not find viable virus
Perhaps if you found a victim of small pox frozen in a glacier somewhere you might find viable virus.
I suspect you are thinking of anthrax spores which can survive in the soil for decades.
