Firstly, let’s take a look at what browser hijacking means: your browser is either the home page that you see when you log on to your computer or the search engine that you use (Google, Bing or Yahoo for example). Fairly self-explanatory; hijacking means the same as it does in the regular definition of the word: it is taking something over by force – so in this case, it is your computer’s browser that has been taken hostage. It overrides existing search settings and changes the default search providers in all web browsers. DnsBasic.com even creates a process which runs in the background of your computer and obviously may impact the performance of the system.
It’s a typical day, you log onto your computer and hit the internet icon; the first page you see is your home page, be it your PC’s default page or one that you’ve set yourself, such as your email login for a favourite news or sports website. You then decide to look something up on the internet – perhaps that new restaurant that you want to try out tonight – so you go to one of the search engines but they’re new and their site is not online yet and you get an error page. What’s my point, you ask? Well, the point is that because, as seen above, these three pages are browsers, they are also vulnerable to browser hijacking.
But what does this hijacker actually do? Someone who is hijacking your browser is ultimately taking control of how it works and is configured – this often takes the shape of a new toolbar. They might also change what you see on your home page. This is sometimes known as a ‘drive-by download’ because the tool bar is installed without you being any the wiser – computers with poor security or no antivirus software are particularly in danger of this. Dnsbasic.com for instance, won't hijack your home page but it will change the way you search directly through the address bar or omnibox in Google Chrome. Search results are mixed with good and poor quality links. I wouldn't recommend using this search engine, especially when you can use Google or Bing instead.
At first glance your new search engine provider might not look so sinister – surely it’s just providing you with some extra functionality, right? Wrong: your new super-helpful search engine is actually there to redirect you to websites that you otherwise would probably have not clicked on.
In the majority of cases the dnsbasic.com will have been installed by downloaded software or shareware even from an infected email.
Dnsbasic.com can be tricky to remove, even for the techy guy at your local computer repair store, as the technology behind them is increasingly sophisticated, so it stands to reason that prevention is better than cure. Please use the following removal instructions to remove dnsbasic.com from your computer. If you have any questions, please leave a comment below. Good luck and be safe online!
