Custom Search Bar

Custom Search Bar is an unwanted software component that introduces changes to the main browser with the aim to aggressively popularize low-ranking sites. Custom Search Bar is often distributed and installed with the help of rogue sites and file-bundles and could potentially lead to security issues.

Custom Search Bar is a piece of software that can be referred to as a PUP (potentially unwanted program) or a browser hijacker. The main functions of apps and programs of these categories are to draw in more views to certain websites and serve as online advertising tools by spamming the users’ browsers with endless streams of advertising materials in the forms of pop-ups, banners, page-redirects, pop-unders, and more. The effects of an unwanted app like Custom Search Bar could be experienced in any browser, including Chrome, Firefox, Opera, Edge, etc.

Additional symptoms associated with such apps are default search engine and homepage replacement as well as other potential unauthorized changes that could get introduced to the affected browser without the user’s informed approval. Even though none of the aforementioned effects that Custom Search Bar may have on the browser and computer are directly harmful or threatening, they could potentially expose the user’s system and virtual privacy to a number of risks, albeit in an indirect way.

Why Custom Search Bar should be removed

There are quite a few reasons why it’s best to ensure that any hijacker current present in your system gets deleted ASAP. First and most obvious is the fact that a software like this one could greatly decrease the quality of your browsing experience by frequently interrupting you with its ceaseless flow of advertisements, and by making changes to your browser that make using the latter less efficient.

However, an even bigger reason to uninstall software like Custom Search Bar is that the ads and page-redirects it spams you with as well as the undesirable changes introduced to your browser could potentially make your computer more vulnerable to various types of malware, including Trojan Horses, Spyware, and Ransomware. Additionally, some of the ads and redirects could lead you to scam pages with phishing forms where, if you are not careful, you may end up sharing sensitive personal data, such as credit or debit card numbers, with online scammers. For these reasons, and other similar reasons, we strongly recommend that you do everything you can to delete Custom Search Bar and anything related to it from your computer.

In the end, even if the presence of this browser hijacker doesn’t cause any serious negative impact to your computer, it’s still a piece of software that likely has no practical use for you, and so there’s no reason for it to remain on your computer.

Protecting your browser in the future

The main thing you need to remember in order to keep your browser safe and clean in the future is that most browser hijackers rely on the users’ lack of attention to small details such as the custom settings menu in an installation wizard or the random pop-ups that various sites put on your screen when you try to visit them. For instance, a lot of hijackers like Custom Search Bar and Active Search Bar are added to the installers of other, more desirable, programs as bonus components that most users do not notice and thus do not leave out of the installation. Similar is the case with site pop-ups that may initially seem like captchas, but are actually permission buttons that, once selected, would allow the hijacker to gain control of your browser. It is, therefore, important to always pay attention to anything that seems out of the ordinary so that you don’t have to deal with it at a later time. Also, obviously, keeping away from questionable websites and content, and not downloading suspicious software is extremely important if you want to keep your computer and data safe and secure and if you want to prevent violations of your virtual privacy as much as you can.
