Am new to this, so unfortunately have the odd question that will have you experienced players face palm at my stupidity.
I've checked the rulebook but I can't work out which virus counters are purged when the Corp spends their 3 clicks.
Is it just the ones on their cards (and does this include any viruses being hosted by their cards?) or does it cover all the virus cards owned by the Runner as well?
I'm assuming the former, but if somebody could point me to where I get the answer, that would be great!
Thanks in advance.
