Browser hijackers – how do they work?
Browser hijackers are programs that are developed to display a wide variety of ads on the user’s screen while they browse the web. This is perfectly legal activity; however, it may cause some disturbance and decrease the quality of the online experience due to the dozens of undesired messages, popping boxes, page redirects and new tabs that constantly appear. As a typical browser hijacker, iStart123.com could be related to all the activities described above. When this program operates on your system, you will probably notice some undesired changes in your browser like a different homepage, a change in the default search engine or a new add-on in the taskbar. Even your searches are more likely to be redirected to some promotional pages, hot offers, new products or sales.
In case you wonder why anyone would need to create such an annoying piece of software and bring you this entire disturbance, you should know that money stands behind it. While it may not really provide some real value to the users, this program is mainly used to generate profits for its developers through a method called Pay-Per-Click. Every click that the intrusive ads can get converts into income. That’s why the developers try to collect as many clicks as possible by displaying huge amounts of ads. This revenue usually helps them support their own software and promote it for free while earning from the ads. The developers use a method known as a software bundle that distributes browser hijacker programs along with other applications you may download from the web. This is the most common way to get iStart123, but you may also find it in spam emails, torrents, direct downloads or platforms where software is distributed for free.
iStart123 looks like a virus, could it be one?
Rest easy, contrary to what most people believe iStart123 is not considered a virus. Often, you may read about browser hijackers and their annoying activity being compared to a virus infection. Due to their rather aggressive way of displaying ads and page redirecting, these programs may indeed be easily mistaken for malicious. However, browser hijackers like iStart123 aren’t considered as such a serious threat. Security experts even consider them as harmless applications, compared to malware like Ransomware, Trojans or viruses. The worst that a browser hijacker can do is to bombard you with ads and interrupt your browsing by redirecting your searches, but it surely does not contain malicious scripts that could directly harm your system. Just for comparison, Ransomware contains a harmful script that could encrypt all your files and prevent you from accessing them, which is a really nasty and malicious action.
There are some security risks we should warn you about.
Even though browser hijackers are not capable of malicious actions themselves, there are some security risks we should warn you about. Since malware uses all the options to infect more and more unsuspecting users there’s still the possibility of coming across misleading ads which may somehow appear among the real ones. This could happen if you click on them, while you are trying to close the dozens of pop-ups that are flooding you. Although the chance is still small, you may get redirected to an illegal website or content with malicious payload. While this is a risk you can’t predict, it is a good idea not to click on any of the ads, even if you try to close them, or better just remove the browser hijacker from your system.
How to remove iStart123 completely?
As you have probably realized, browser hijackers are way harder to remove than the way they get installed. You can’t uninstall them the usual way you uninstall software because the ads-generating files usually integrate deeply inside your system files. In most cases, you need to detect them first and then delete them manually. This is exactly what we are going to show you in the removal guide below. And if you don’t want to get iStart123.com again, it is a good idea to avoid installing software from free platforms and always check what comes with it in the bundle. This could be easily done when you run the installation, click the custom/advanced option and manually unselect the potentially unwanted software that is bundled in the package. The next time you do this, you won’t have to deal with browser hijackers or any undesired bloatware later.
