Defense-software.com Ads is a browser hijacker targeting Macs

Defense-software.com Ads is a redirect virus that affects Macs, also called a browser hijacker. Since their primary intention isn’t system harm, they’re classified as pretty minor infections. However, it is not benign either as it aims to generate traffic and profit and it will do that by leading you to suspicious web pages.

Summer Locker Ransomware

Even if hijackers can install silently, their behaviour once installed is an immediate giveaway. Your browser will very obviously be acting strangely, search results will be a mixture of sponsored content and legitimate results and you’ll be randomly redirected. Some users, however, might not associate the unusual behaviour with browser hijacker if a browser hijacker isn’t something they’re familiar with. A simple search of the signs/web page redirected to with a search engine generally points users to a hijacker.

The hijacker will not only redirect you, but will also make changes to your browser. Your browser will have a different homepage/new tabs, and it may be complicated to undo these changes. The reason your browser’s settings are changed is so that the hijacker could redirect you.

Plenty of users think that hijackers are malware or viruses, which is incorrect, meaning they do not just install without requiring your permission. Users commonly allow them to install, although they normally do it without realizing it. Hijackers, among other pests like adware and potentially unwanted programs (PUPs) are added to freeware as additional items, and when users install the freeware, they end up installing the attached items as well. It’s not difficult to prevent these undesirable installations, as long as you are aware of how to do it, and we’ll clarify in the proceeding section.

Even if the hijacker isn’t particularly severe, the sooner you uninstall Defense-software.com Ads the better. You could be exposed to dubious content by the hijacker, such as malware and scams, in addition to causing disruptions to your regular browsing.

Ways a hijacker installs

Browser hijackers install with freeware, as we have said above. Program bundling is how this method is called, and it is essentially attaching infections like hijackers to free programs as additional items. Software bundling is quite questionable because while the offers can install alongside the free software, users don’t initially see them. The installations aren’t difficult to avoid, however, if you pay attention to software installation processes.

When you’re installing free software, choosing Advanced (Custom) settings is important. The added offers will be hidden if you pick Default mode. However, Advanced won’t only make them visible, but also allow you to uncheck them. Unchecking the items will be enough to prevent them from installing. Once infections are already installed, it is much more time consuming to remove them, compared to blocking their installation from the very beginning. And actually paying attention to how you are installing applications will prevent your computer from being filled with junk programs.

More details about the hijacker

Not long after installation, redirect viruses hijack browsers like Safari, Google Chrome and Mozilla Firefox, and start to redirect to weird websites, which makes them immediately obvious. The browser’s homepage and new tabs will be set to the hijacker’s advertised web page, and that is the site you will be redirected to whenever you open your browser. In addition to a different homepage, you will also have a new search engine. When you search for something through your browser address box, you will be redirected to a website the hijacker is promoting and then get your search results. Those results will probably be altered to include sponsored content that doesn’t actually relate to your searches. The hijacker carries out those redirects so it could generate page traffic and profit. The random will not only be highly irritating but they may also put your system in danger. Therefore, it is suggested to not engage with any sponsored content or adverts while the hijacker is still installed. You may be redirected to sponsored pages that may not be safe because hijackers do not review whether they’re secure. The web pages you get redirected to may attempt to fool you into installing malware or promote all kinds of scams. That’s why you shouldn’t permit hijackers to stay installed, even if they aren’t directly harmful to the system.

The hijacker will also collect information about you, including what you search for, what content you interact with, the websites you visit, your IP address, etc, it’s essentially spying on you. The hijacker could later share the data with unknown third-parties, and it’s doubtful you want that.

In general, the hijacker installed on your Mac without needing your permission, made not wanted modifications to your browsers, began redirecting you to sponsored web pages for revenue, and possibly subjected you to unreliable content. don’t hesitate to remove Defense-software.com Ads even if it doesn’t seem like the most severe infection.
