Since yesterday is very likely that the following has occurred to you: the Chrome and Firefox browsers have qualified several websites with links to P2P download sites with malicious code as showing a warning with a completely red background and quite apocalyptic. It is the case of Rarbg, ExtraTorrent or KickassTorrents, among others.
This is not a lock, but the page acts almost as one apparently offering a unique option to return to the page where we were before. You can always move forward "at your own risk" if you click on Details, then click the button to go to the website anyway. It is quite hidden, but not impossible to find.
Right now many of these sites have already solved this problem, but when Google still had active websites qualified as simply "suspicious" warning that some sites could install malware that installs additional listings in secure sites. And remove the malware, in some cases, it is quite complicated.
The question is: why suddenly Chrome and Firefox have called P2P download sites as suspects so quickly? It is impossible not to think of some kind of strategy behind this movement, while still allowing access to the sites is able to scare away the vast majority of people. Meanwhile, Google has simply been limited to reiterate its policy of protection from some websites containing malware.
