When I open different websites, in some of them there are a lot of ads by DNSUnlocker, I already changed my DNS to Google DNS, but my problem hasn’t solved by now. Please Help.
MacBook Pro with Retina display, OS X El Capitan (10.11)
Download and run Malwarebutes Anti-Malware
It's free.
Then quit and relaunch Safari.
See if that deletes the DNSUnlocker ads.
First, never use any kind of "anti-virus" or "anti-malware" software on a Mac. That's how you create problems, not how you solve them.
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Extensions
Uninstall an extension named "DivX Plus Web Player," if it's present, as well as any other extensions you don't know you need. If in doubt, remove all extensions. None is required for normal operation.
Do the equivalent in the Chrome and Firefox browsers, if you use either of those. You may also have to reset your Chrome profile.
