Should I continue using search engine?

Questions about virus

Make sure you do not run into virus when looking for an alternate search engine. It is a questionable browser hijacker type program[1], which targets Mac users. It slithers into a computer in the form of GiantSender.dmg file[2], which immediately replaces your homepage with search engine. We must point out that GiantSender is a product of Tabatoo, Ltd., which claims that it collects “information you provide us with: Tabatoo may collect information you enter to the website, including but not limited to information you provide at the registration process.” It means that this tool can store your email address, also email addresses of people that you try to transfer files to. On top of that, this controversial program uses common tracking measures such as cookies and web beacons, which help to gather personally non-identifiable information, such as search queries, browsing history, browser type, IP address and so on. All this information helps to ascertain your interests to deliver targeted ads later on. These ads are going to be delivered alongside search results whenever you search via However, pay attention to the fact that this search engine delivers modified Yahoo search results. The tab name on results’ pages always points that it is Genieo Yahoo Search results, which means that search results are supplemented with ads from a content recommendation engine Genieo[3].

Clicking on sponsored search results by Genieo can be dangerous. You can never know where they will take you, and what websites hide behind these sponsored search results. In the best case, you can end up on secure websites, but you might also be forced to visit shady-looking or insecure Internet pages. The Privacy Policy of this browser hijacker states that “the website” may contain links to third-party websites that contain co-branded products by Tabatoo or its affiliates, and that “Tabatoo is not responsible for third party sites and services and is not liable in any way for any result of your use of these.” Therefore, keep in mind that you might run into unsafe web pages when exploring search results, so be careful and do not trust them! You can unintentionally install a safe-looking Java or a different update without realizing that it contains harmful or spyware-type elements. This can cause annoying problems such as the repetitive appearance of pop-up ads, browser redirects, or even more severe problems. Therefore, we believe that you should remove redirect virus from your Mac immediately. You can do that by using Malwarebytes or manual removal guidelines presented below the post.

How did I infect my Mac with this hijacker?

Macs can be infected with spyware programs, too. Apparently, your Mac is being affected by hijack[4], which doesn’t let you change your homepage or get relevant search results. So it means that this potentially unwanted program (PUP) somehow managed to be installed on your computer, and it did that with your permission. That is right – spyware programs are not illegal, and they use tricky, yet legitimate ways to talk the computer user into installing them. Most likely you have agreed to install it alongside another free application that you recently downloaded to your Mac. To find out what additional apps and browser extensions come with your selected program, make sure you choose Custom/Advanced settings for the installation[5]. If you find any optional programs in these settings, deselect the agreements to install them. It is also strongly advisable to read Privacy Policy and Terms of Use documents thoroughly.

How to remove hijacker?

Do not let this annoying program control your Mac’s browsers no longer. Simply remove virus by following instructions that we provide, or employ a powerful anti-spyware or anti-malware program and let it do the cleaning. Please remember to be careful when installing new apps to your computer, and do not let any suspicious programs slip into the system unnoticed.
