A few words about a browser hijacker’s typical behavior

In this digital age, when we browse the web, we commonly come across many advertisements and this is perfectly normal. However, sometimes an excessive amount of ads, banners, popping boxes, new tabs and page redirects may come from specific software that is installed on your computer. This type of software is called Browser hijacker and Error SL9DW61 is exactly one such piece. Developed just with the idea of displaying as many ads as possible and redirecting you to as many sponsored pages as possible, more often than not, this program may heavily annoy and interrupt the users’ normal browsing activity. This is probably the reason why you (and many others) land on this page and seek for salvation from the disturbance.

But why are the browser hijackers causing you such inconvenience?

There are many programs (mostly free ones) that may come with ads-generating functionality. However, most of them provide some useful service for the users. Browser hijackers, on the other hand, may not really provide any usefulness, except the excessive amount of ads they display. In fact, the purpose of these programs is another – they are developed to generate income for the developers through a method called Pay-Per-Click. This is a remuneration method that many businesses, programmers and software creators use to earn some money from the clicks on the ads that the users see. In fact, through Pay-Per-Click every click turns into income and the more clicks the ads get, the greater the income. This explains why users are bombarded with dozens of pop-ups, links, ads, banners and pages all over their screen. The good news is that there is a way to permanently remove them, and in the next lines we are going to show you how to do that.

How can a browser hijacker get inside your system?

Programs like Error SL9DW61 may find their way to your system through various distribution channels. First of all, we should say that these programs need to be installed like any other software that you install on your system. They do not “infect” you unknowingly, although you may not really notice when you got them installed. The reason is that usually, browser hijackers come along with other software you install. This happens through a software bundle you may get from a free download platform, direct download from the web, open source download platform, spam emails, different file sharing sites or installation managers. That bundle usually contains the program you want, plus some additional applications, which will get installed the moment you run the setup. Most users don’t know this and proceed to the standard installation. But there is a way to prevent that: during the setup, simply clicking the advanced/custom option will open a menu where all the add-ons in the bundle can be manually deselected. This is where Error SL9DW61 usually hides and with a simple click you can prevent it from getting installed. Unfortunately, you have probably skipped that step the last time, and now the uninstallation process would take you a bit more effort than a single click.

If Error SL9DW61 behaves aggressively, calm down, it’s not a virus!

While Error SL9DW61 operates on your computer, the intrusiveness of the ads may really appear like a nasty virus infection. However, browser hijackers, luckily, do not contain harmful scripts and are not meant to perform malicious actions. Yes, they can be really irritating sometimes, however, they have nothing in common with malicious threats like Trojans, Ransomware or other harmful viruses. Unlike the illegal forms of cybercrime that destroy your system, steal your credentials or blackmail you (Ransomware does that), Error SL9DW61 is legitimate software and at its best could only expose you to undesired ads. Of course this may also hide some risks, but they are not directly related to the program itself. For example, you may happen to click on a fake redirecting link or an ad, and land on a compromised web page, where malware could be found. Some Browser hijackers may collect information about your online activity and the pages you visit or the things you search for on the web, so they can display relevant ads and increase the chance of you clicking on them. But in most cases, just the irritation from the unstoppable ads is enough for users to decide to remove this type of program. If you have also decided to get rid of Error SL9DW61, just read the following instructions below.
