Apologies if this is the incorrect forum for this question.

Let's say that I decide to visit a string of shady websites - the kind with 20 pop ups referencing adult content and fake antivirus software.

I don't plan on entering credentials and being phished. I don't plan on executing any files the site might decide to place in my Downloads folder.

How likely is it that my machine is compromised, if I do not click on anything?

How likely is it that my machine is compromised, if I decide to click on every button I see?

I suppose the site could exploit an unpatched or even zero-day browser vulnerability - how common is that? I believe "drive-by" attacks might fall under that umbrella, but I'm ignorant on how common these attacks are today.
