@Phoenix32890,
Well, it wasn't a virus per se, it's an application you downloaded and was
infested. So unless the user downloads the "virus scanner" nothing will happen.
I've used a MAC for 20 years and never had a virus, Apple's built in virus
scanner is pretty reliable and shields you from an outside virus. However,
if you download software that is not a legitimate source, all bets are off.
Usually the OS will ask you if you're sure to download a certain file and the
system does have safety features prior to downloading the file, but if you
do it anyway, it certainly can happen.
In this case however, I think they wanted to have your credit card information as it was a phishing scam.
