I doubt the anti-virus by itself would include ad-blocking – you’d have to have the Internet Security suite, or perhaps just Firewall.
The day anti-virus programs come with ad-blocking built-in, is D-day for online advertising as we know it. Billions of dollars down the tubes across all online industries.
OTHO, I would like to see anti-virus block spam… LOL… the trouble is, how would it be able to tell spam from legitimate newsletters that people have subscribed to?
