What is Questsdns.com?
Questsdns.com is a domain which contains a fake Internet search engine. It looks quite trustworthy when you look at it for the first time, but, luckily, specialists are not so easy to fool. They have immediately understood that this search tool is a part of a browser hijacker infection and, as a consequence, cannot be trusted. In fact, they suggest going to implement the Questsdns.com removal the moment it shows up on browsers.
First, it cannot be called a trustworthy search tool because it is set as a homepage and default search engine without the user’s agreement. Second, it generates tons of commercial advertisements which might be placed on the faēade of Questsdns.com or be shown next to search results opened for users. Last but not least, there is a possibility that Questsdns.com will redirect users to pages with malicious software. As can be seen, there is nothing good out of keeping Questsdns.com set on browsers, so you will not regret getting rid of it too. You will find a thorough explanation about the Questsdns.com removal in the last paragraph. You can go to read it immediately if its deletion is your only goal; however, you should definitely read other paragraphs too if you want to find more about this browser hijacker before getting rid of it.
How does Questsdns.com act?
Questsdns.com is full of third-party links. We call them sponsored links because their purpose is to promote third-party pages. These links do that by taking users to certain pages. Since money is the main goal of the developer of Questsdns.com, links leading to bad websites might be provided for them too. Users do not even suspect about that and surf websites they are redirected to fearlessly. Surfing bad websites might allow malware to enter the system. Unfortunately, it is hardly possible to distinguish those bad links from decent ones, so the best would be not to use Questsdns.com at all as a search engine. Uninstall Questsdns.com from web browsers as soon as possible because it might be too late to do that the next day.
