This page aims to help you remove Ads by Leadbolt. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

The annoyance that online ads may bring really make your browsing experience very frustrating yet, in most cases, it is inescapable to encounter some form of advertising activity while browsing the net. However, something that many users fail to realize is that not all online ads are coming from specific sites and pages. In fact, there is a type of web advertisements that are getting generated directly by the user’s browser or rather by an app installed inside the said browser. If you have such an app on your Chrome or Firefox or whatever other browser you use as your default, then you will likely have ads streamed on your screen on pretty much every site and page that you visit – even on ones that do not normally show advertising content. The category of software that causes this uncontrolled display of pop-ups, page redirects, banners and other types of ads is called adware and the whole purpose of the representatives of this software family revolves around making money via such advertising campaigns. The more the ads on the users’ screens, the greater the chance that some of them would get clicked upon which would, in turn, generate money for the people behind the adware. This type of revenue-generation methods are typically known as Pay-Per-View or Pay-Per-Click. Now, this sort of activity in your browsers doesn’t directly threaten the safety of your computer since adware apps aren’t really dangerous and malicious malware infections the likes of Trojan Horses or Ransomware cryptoviruses and screen-lockers. However, removing any adware from your computer is still the best course of action in case you have such a component latched onto your browser. Here, we will help those of you with Ads by Leadbolt (a highly annoying and recently released adware) on their computers remove it and fully uninstall it from their browsers.

Some potential hazards you ought to be informed about

As you all probably know, interacting with random advertising messages and links on the Internet is hardly a good idea as doing that could put your computer at risk. Well, this applies even more to the ads that get displayed by adware applications like Ads by Leadbolt – you really can’t put your trust in the ads that adware tends to generate because, even if a lot of the advertisements may be legit and may even link you to interesting offers, others could easily be misleading and trick you into installing more low-quality and unwanted software or maybe even land you on pages and sites with shady, obscene or harmful contents. It’s even possible that nasty infections like Ransomware, Spyware and Trojan Horses as well as other viruses could target your computer if you aren’t careful with what type of ads you click upon while an adware app is active in your browser. Naturally, the best thing you could do in such a situation so as to keep your computer away from danger is to eliminate Ads by Leadbolt and by doing so stop the uncontrolled stream of ads targeting your browser.
