This page aims to help you remove Logger.js/Haso.pubmatic.com. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.
In the event that you’ve been infected by Logger.js/Haso.pubmatic.com, there’s little to no way of mistaking it with another type of program. As a typical member of the adware family, Logger.js/Haso.pubmatic.com is designed to flood your browser with a stream of adverts of all the shapes and sizes you can imagine. You might have even experienced certain changes to your browser settings, such as your search queries being redirected to a different search engine, from the one you had set, and upon opening your browser there might be another homepage there to greet you, from what you last remember. Many users have found that even though they’ve tried to change the settings back to the way they were, it didn’t have much effect, as the next time they started their browser – it was as if they’d done nothing. In addition to this, nothing that they’ve tried to stop the numerous ads from appearing has worked either. Many install popup blockers and other ad-blocking and ad-filtering programs on their computer, but this, too, fails, because those tools are designed to battle ads that are generated by websites and not a program that’s firmly seated within your system. So, the point of this article and the guide below it is to show you how to remove this pesky software from your computer and avoid getting infected in the future.
Why the many ads?
Adware developers earn money based on the amount of times their ads get clicked. This means that it’s in their best interest to produce as many as possible and place them on as inconvenient for the user places as they can. This is probably the most annoying part, because you may have yourself felt what it’s like when you’re trying to navigate a certain page, but end up opening some new tab or window. However, the developers also strive to make the ads appealing to increase the chance of gaining more clicks. So, to do this, their software – be it Logger.js/Haso.pubmatic.com or another program of this type, has been programmed to collect information regarding your browsing activity. Things like the pages you visit, the topics you search for online, your most frequently visited and favorited websites, along with any details you may have entered are all gathered and stored by the ad-generating program. This allows it to later produce content that would be more relevant to you and though this might sound very clever and convenient at first glance, there’s more than just one side to this.
The data that’s been gathered on you is often sold to third parties for the extra few bucks, once it’s no longer needed. Most times this is even stated in the EULA of the program, but who reads that, right? But even so, many users still consider this to be a violation of their privacy and adware is therefore also classified by security experts as a potentially unwanted program, but not only because of this. There’s also the fact that an advertising campaign that’s been created for each and every specific user cannot be expected to be 100% legit. One way or another, if you start clicking on the ads (which we do not advise for reasons we’ll explain later) you will soon find that by far not all of the ads actually answer to the content they redirect you to. In fact, a lot of the ads are downright misleading. On very rare occasions, those ads could even lead you to dangerous websites with all sorts of malicious programs lurking on them. You could this way fall victim to some virus such as a Trojan or ransomware, and this should hardly come as a surprise, as ransomware is actually most commonly distributed through malvertisements (malicious advertisements). Don’t jump to the conclusion that Logger.js/Haso.pubmatic.com is a virus, though. It’s not. As pointed out, it’s more of a PUP and most adware is actually completely legal. Nonetheless, it is our advice to you to remove it from your PC, as aside from the aforementioned effects it may have on you, its long-term presence on your computer may cause it to slow down and malfunction.
When it comes to unwanted programs, be it of the annoying or malicious type, it’s important to avoid getting them on your machine altogether, as opposed to cleaning up the consequences. Be very cautious with the sites you visit and be even more cautious with the content you download from them. Programs like Logger.js/Haso.pubmatic.com are usually distributed through program bundles, usually with various freeware and shareware. So, aside from filtering your download sources, you should also always customize the setup of any new program you install. This will allow you to leave any unwanted contents behind.
