Say you have a jar of perserved peaches that has been preserved over a hundred years. The lid is sealed tight so no entering microbe can seep through. How does a virus get in there?

Viruses need a living cell to enter in order to replicate. A virus could have lain dormant in the unopened jar of preserved peaches from the time it was sealed. You didn't state how the peaches were preserved. If canned hot to kill microorganisms, viruses are resistant to heat, but the heat would kill any living cell which they need to replicate.
Viruses replicate using the machinery of living cells so come from living cells. Where the first virus came from is not known, neither is where life (living cells) originated on earth known.

Viruses are on the borderline of the living and non-living worlds. Thus they can survive very extreme conditions.
