Note that everything is commented out with characters, meaning that nothing is actually being read from the hosts file. Modern versions of Windows include a sort of DNS system already, so if you visit localhost it'll automatically redirect you to If you're doing some local development and are having problems with localhost, you can just remove the comments from your hosts file:.
Then, open PowerShell by pressing the Windows key, searching for "powershell", and clicking "Run as Administrator":. After that, you should be able to visit localhost in your browser and see whatever you're hacking on. If you're still having issues, try closing your browser completely, then open a new browser window and try again. Even though hosts files have fallen out of favor with newer systems like DNS, they still work for legacy reasons.
And hackers have definitely taken advantage of this in the past. What they would do is point a common website like google. This IP address could serve a site that looks just like Google's, but is actually trying to steal your sensitive information.
While this was a problem in the past, most security software like the Windows Security Suite can recognize and fix problems with the hosts file automatically. That said, if you open up your hosts file and see a lot of strange entries, then you may want to revert to the default Windows hosts file. Just copy and paste the default hosts file from earlier in the article into your hosts file and save. Note that some third-party security software uses the hosts file to block dangerous websites.
