When did the Pirate Bay become full of malvertising?
I hadn't been to the Pirate Bay in quite some time. I occasionally pop over to look for old videos. I went today and a big popover for a dubious software upgrade came up. Then, another saying that my system is infected and offering to clean it. That's obviously fake, but it was blocking my access to the user interface so I wasn't able to complete my search. Closed it. That's unfortunate.
If you're using a recent version of Chrome, Google has stunted the capabilities of many ad blockers. Suggest using another browser and/or using something that catches this stuff before it gets to your browser like a properly configured pihole. Otherwise, configure your ad blockers more aggressively, especially for sites that are less likely to screen their ads.
