I wonder if that has happened from ABP's approved networks. From what I recall, their criteria are rather strict, and I would expect a network to get banned if that happens.
To be honest, pretty much the only ads I notice are sponsored results from Google (static text). I also use uMatrix for untrusted sites.

Google's AdSense has delivered malware in the past. And nobody is about to ban them.
It doesn't matter if it's just a "text ad" either. They allow a script, which means a malware payload can get delivered.
Google do a fair effort stopping malware, something like 400,000 malware ads try and host themselves through their network every day. But some do get through.
