Wow.
Bad news in multiple ways, those sites.
I’ll look at G rated model sites if I get the urge :)
It won’t help. We have people get infected trying to find code examples. If you leave a commercial site up long enough, you can expect malware. Companies can’t control their banner ads.
If you are going to browse around, you should create a user with the lowest level of authority and use it to browse. If all you got was malware, count your blessings. I left a share open on the work network with no security as a test and it got ransomed in a few days.
