Here is the situation.
Parasite has 3 virus counters on it and is attached to Data Raven. The runner also has Data Sucker with 1 virus counter.
When the Runner approaches Data Raven can they avoid choosing between taking a tag or ending the run by using Data Sucker to destroy the ice (lower its strength to 0, triggering parasite)?
Does this scenario play out any different if they have Ice Carver?
