OnShopBase Scam


OnShopBase

OnShopBase is a browser hijacking piece of software which can show unwanted ads in your web browser and redirect you to different sites without your approval. In order to promote its ads more effectively, OnShopBase can install different helper components inside the system’s default browser.

The OnShopBase Scam

The OnShopBase scam can integrate with common browsers like Chrome, Edge and Firefox, but other web browsers can also become a target of this program and have their settings changed without notice. This is because the OnShopBase scam operates as a browser hijacker and is programmed to make browser modifications in order to facilitate the promotion of different ads, banners, pop-ups and sponsored web links during the users’ web browsing sessions.

If you are on this page, you are probably not only annoyed by the enormous amount of advertisements and redirect prompts that constantly show up on your screen, but also by the unauthorized changes that OnShopBase com has imposed to your browser’s homepage and the default search engine. Fortunately, these changes aren’t fatal for the operation of your computer and can be removed with the help of certain instructions or a professional removal tool like the one that you will find below.

But if you don’t do something about them, they can be unsafe in the long run. This is because the randomly displayed ads, pop-ups, banners and redirect links provided by OnShopBase are typically one of the most common methods of distribution for infections such as Ransomware, Trojans and other viruses. You can easily get infected by malware of this kind if you happen to click on such an ad and it turns out to be misdealing or infected. Therefore, on this page we will show you how to permanently remove these ads and how to uninstall their source.

The OnShopBase Virus

The good news is that the OnShopBase virus that stands behind the ad-generating activity is not a serious online infection but a browser hijacker which is, basically, an online advertisement program that does not usually pose a safety risk for the computer in which it operates. The OnShopBase virus is responsible for the display of various aggressive advertisements on the user’s screen and some potentially unwanted modifications to their web browser.

For example, browser hijackers like OnShopBase, Maincaptchasource, iStart Search Bar may introduce a new search engine to your browser which is programmed to show mostly sponsored search results and pay-per-click advertisements as the top of the page. In addition to that, the program may try to promote a specific website by replacing your homepage address with its address so that every time you open a blank tab, that URL will automatically be loaded. Additional toolbars and buttons may also be installed inside the hijacked browser and some of them may even look attractive and helpful. However, clicking on them may often redirect you to unfamiliar or sketchy web pages and may expose you to even more pop-up messages, banner ads and promotions on your screen. And given the likelihood that a malicious virus (such as ransomware or a Trojan) may hide inside some of these messages it is best to avoid the danger by not clicking on anything. Security experts even advise to uninstall the browser hijacker that displays these ads and makes modifications to your browser as this is the most effective way to prevent a close encounter with different online hazards.
