Advertising is malware
In my view, everyone should avoid all ads, because all ads present a security problem. Online ads certainly have the potential to have an embedded browser exploit, but even offline ads are still usually malware. Advertising takes heavy advantage of psychological research on the flaws in human decision making, and a large proportion of all advertising is attempting to bypass the viewer's rational processes and influence them to make a decision that is not well considered.
I understand that many businesses depend on advertising for their revenue. But I don't see why I should subject myself to adverting because of that. My desire to avoid attempts to hack my brain overwhelms any concern I have for the economic viability of a business.
