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.
First Rule: don't rawdog internet, especially torrent search sites. Always use protections.
Second rule: always check if you're on the right site. It's relatively easy to find torrent search sites, but even easier to find phishing sites (i.e. sites that claims to be the original site, but they actually aren't).
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.
using multiple adblockers can cause conflicts and can sometimes outright negate the functionality of all of them. ublock origin updated regularly will block all of your ads no problem, anything more than that is both redundant and somewhat harmful.
Sadly almost all these comments are wrong. I work in a computer shop and we see the scam you're talking about all the time. It happened because you unknowingly opened an ad. So you clicked on a button that looked legitimate like "download" or "next" or whatever, and that pops up full screen. The fix is a good ad blocker like ublock origin. Google's being a piece of shit right now about ad blockers so I recommend something Firefox-based for effective ad blocking.
The front page of the official site has always been pretty clean. But if you click that search button or try to go through results without a decent ad block, they lay it on pretty thick.
