content: Well, it doesn't seem to be blocking those sites for me. So maybe they got reported for malicious content? I've seen that before where I get a similar message for a site that contained malicious ads. Though there was an option at the bottom to continue after you clicked "details." EDIT: It appears that some of the sites have resolved the issue. Details can be found at TorrentFreak: https://torrentfreak.com/chrome-blocks-major-torrent-sites-over-harmful-programs-150710/ Apparently the same thing was happening to some people on Firefox.
