Now you can use OpenDNS to secure your Mac OS from malwares and trojans.
You can eliminate your worries about malwares and trojans that may attack your Mac machine by using OpenDNS, which will automatically block malicious trojans like Flashback forever.
Adding OpenDNS addresses (which is completely free to use) on your Mac Network can be helpful in many ways. For example, apart from restricting access to malicious content, OpenDNS can also stop browser redirects and block inappropriate websites permanently.
Step 1: Launch System Preference.
Step 2: Go to Network.
Step 3: Select the Advanced tab.
Step 4: Go to DNS tab and hit the + button.
Step 5: Add these IP addresses as shown in the screenshot below: 220.127.116.11 and 18.104.22.168.
Hit OK. That’s it!
Along with making your Internet faster and more reliable, OpenDNS will also protect your Mac — iMac, MacBook Pro, Air — from future, widespread malwares, trojans or viruses. Even Windows users can use OpenDNS to protect their computers.
