Remove Defense-Search
Defense-Search is a shady browser add-on, whose name suggests that it is meant to enhance your safety while searching the Web. Allegedly, Defense-Search helps filter out potentially dangerous results, and gives you a safer browsing experience. In reality, the only purpose of Defense-Search is to replace your browser configuration by forcing you to use an alternative new tab page and search engine.
As some of you may have already guessed, Defense-Search focuses on promoting a search engine it is affiliated with – Defense-search.xyz. Its creators are likely to receive revenue for all searches performed through it. Furthermore, the Defense-Search results pages may often include ads and sponsored results – further increasing the revenue of the scammers behind Defense-Search.
We consider the Defense-Search app to be a browser hijacker. This means that it is not a threat, but its removal is the best course of action. Browser hijackers like Defense-Search are designed to be persistent and annoying. They will hijack your browser settings, and then prevent you from undoing these changes. The only way to make sure that Defense-Search's changes are gone for good is to eliminate it with the help of an up-to-date anti-malware software suite.
