There is a camp ground not far from me that lists there water as non palatable. Nice high prices in the dessert to camp and non palatable water. Go Figure
This says two drops of chlorine bleach per liter. I double that if in doubt. Use fresh bleach. That does not limit it to viruses, but it would certainly cover viruses after you already filtered it.

I carry a one ounce bottle of chlorine bleach for water treatment as my backup in case filter or Steri pen fails. Chemical treatment involves a delay, generally half an hour.
The term is potable water, not palatable when it comes to water supplies. I have tasted some water that was not very palatable, but it was potable.

Keep in mind that viruses are rarely an issue in the wild, that is more of an issue where human wastes may have contaminated the water. That said, in karst topography you can have problems in areas that appear to be pristine that are not necessarily so. And that includes springs in karst areas.
