Sigonews How Did I Get It and What Does It Do?

The Sigonews site uses a couple of delivery ways to spread its hijacking program. It could be spread with the help of third-party install setups. Bundled software and freeware programs could install the browser hijacker on your computer device. Such installations could be set to put more components along with the default installation. To prevent unwanted programs from installing on your computer can be done if you find Custom or Advanced options to deselect components.

In the above image you can see that the Sigonews site has a page that is spreading the related browser extension with a direct download. The extension is also available on the Google Chrome Store and similar places. Another way for spreading the unwanted application to your browsers and PC might include the use of advertisements and redirects. They will be shown as pop-ups, banners and text-links on websites. Those websites could be affiliated or partnered up with Mindspark. The following browsers can be affected:

  • Google Chrome.
  • Internet Explorer.
  • Safari.

Sigonews is a Web address that is also a host for a direct download of the browser hijacker named Sigonews. That same company has made bulks of programs with browser hijacking capabilities. If you have any application associated with it on your computer, then your search engine, start page and the new tab window of your browsers will be changed to that of the hijacker.

The Sigonews download page is covered with an arrow pointing to a download button. Its main search page when you load a new tab, however, has lots of buttons under the search bar which is very similar to other browser hijackers made by the same company. The page also has a bunch of links in the footer of its main page and search results.

The same page will be placed as your default search engine of the browsers you have, along with its new tab window and home page. A toolbar or a browser extension can be added, as well.

The extension connected to the hijacker does the following:

  • Read and change all your data on the websites you visit
  • Replace the page you see when opening a new tab
  • Read and change your browsing history
  • Manage your downloads
  • Manage your apps, extensions, and themes

Sigonews will hijack your browser software programs and make changes to them, if one of its related applications finds its way to your computer device. Your computer system can become affected due to the installation of bundled applications. A lot of sponsored content and targeted advertisements could be displayed in your search results as seen in the example underneath. Your search queries will all go through the Sigonews addresses.

In case you have the Sigonews search redirect, every single online search that you do, will be filtered by MyWay and also links will generate money for the hijacker owners by pay-per-click monetization. You will get redirected to and witness pop-ups and other advertisements associated with the hijacker.

You should be on alert when dealing with this kind of search engine redirects. Continue to read below to check out what information exactly will be gathered from you.
