Are there viruses that target viruses?

Given that we have for example phages that specifically target bacteria is there something that is like a virus for virus? Not counting antiviral medication.

Kinda but not quite. A virus needs to infect a cell in order to replicate. Another virus can't infect that virus on its own. However sputnik virophages infect cells that a 'helper virus' has already infected and takes over the cell. Kinda comes down to semantics in a way.
