What is it?

DNSwatch is a free service that will check every website address your computer is trying to access. Basically the checks are performed while you're browsing the internet, clicking a link in an email, or running a program "under the hood" trying to communicate with servers for information or updates. This service is brought to you by the MyCERT folks at CyberSecurity Malaysia.

DNSwatch will help you avoid known bad websites or sites that will trick your computer into downloading and installing malicious programs on your computer. Even better, DNSwatch will also prevent you from accessing malicious websites that you may not even know your computer is trying to access. Additionally,  it also prevents  nasty programs from "phoning home" and secretly communicating between your computer and cybercriminals.

How Does It Work?

When you type in the web address (or URL) in your browser and click "Go" or "Enter", your browser then will send the it to our DNSwatch. DNSwatch looks it up in a table, checks it against the list of bad websites, and if it passes, sends back the numeric IP address so your browser knows where to go to get the web page. All this process is performed in milliseconds and will not affect your browsing speed.

If DNSwatch discovers that the web address is associated with badness, you will be rerouted to the DNS Watch landing page.
