Remove Search Completion and isearch.searchcompletion.com

Search Completion is a browser hijacker, which is promoted via other free downloads, and once installed it will change your browser homepage to Search Completion and default search engine to isearch.searchcompletion.com.

Search Completion will display advertisements and sponsored links in your search results, and may collect search terms from your search queries. The Search Completion hijack is used to boost advertising revenue, as in the use of blackhat SEO, to inflate a site’s page ranking in search results.

Search Completion it’s technically not a virus, but it does exhibit plenty of malicious traits, such as rootkit capabilities to hook deep into the operating system, browser hijacking, and in general just interfering with the user experience. The industry generally refers to it as a “PUP,” or potentially unwanted program.
Search Completion is an ad-supported (users may see additional banner, search, pop-up, pop-under, interstitial and in-text link advertisements) cross web browser plugin for Internet Explorer (BHO) and Firefox/Chrome (plugin) and distributed through various monetization platforms during installation. The browser extension includes various features that will modify the default or custom settings of the browser including the home page, search settings and in some cases will modify Internet Explorer’s load time threshold, place a lock file within Firefox to prevent competing software from changing its settings as well as disable the browser’s Content Security Policy in order to allow for cross site scripting of the plugin.

Search Completion got on your computer after you have installed a freeware software (video recording/streaming, download-managers or PDF creators) that had bundled into their installation this browser hijacker. Very often users have no idea where did it come from, so it’s not surprising at all that most of them assume that Search Completion is a virus.
For example, when you install the “Fast Free Convertor” program, you will also agree to change your browser homepage to Search Completion and default search engine to isearch.searchcompletion.com.

However when you uninstall the “Fast Free Convertor” program from your computer, your web browser’s default settings will not be restored. This means that you’ll have to remove Search Completion from your favorite web browser manually.

You should always pay attention when installing software because often, a software installer includes optional installs, such as this Search Completion browser hijacker. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.
