Related. Conspiracy theory websites are also very dangerous places to browse. My grandfather loves conspiracy theories, mostly the ones related to free energy machines, and he told me some sites that he went to. I was curious so I visited a few of them (using Firefox + AdBlock). This was the first time I actually got a virus just by browsing a site. It used an exploit that bypassed the browser download popup security mechanism, and it just installed itself. I legitimately got owned, and I was pissed because that just does not happen to me. Now I understand why my grandfather's computer is unusable nowadays.
