How irritating is this problem? (4 votes, average: 5.00)

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

If you are a PC users who is faced with unpleasant browser – related issues such as unauthorized changes to the browser like replacement of the homepage or of the search engine tool or frequent display of irritating adverts and obstructive page-redirects, then you are advised to read the following article. Here, we will tell you about the browser hijacker software category – this is a category of software apps for popular browsing programs like Internet Explorer, Google Chrome, Mozilla Firefox and so on. The specific thing about the hijacker apps and the actual reason why they are called hijackers lies in their ability to gain control over certain aspects and settings of your browsing programs and impose certain unwanted changes to them as well as force them to carry out certain activities that you might find unpleasant. We already mentioned how if you have such a software component added to your browser you are likely to start seeing many different pesky banners, pop-ups, page redirects and other similar advertising materials on your screen during each and every browsing session. It’s even possible that sometimes you might get ads on your screen when the browser is closed. Also, the changed starting page, the replaced search engine and the modified toolbar are also potential symptoms of the presence of a browser hijacker on your machine which you might find rather unpleasant. In many cases, it is actually claimed that the new components added to your browser such as the custom search engine tool or the new homepage (or new-tab page) would actually improve your Internet experience in one way or another. However, in most case, the main reason why a hijacker might introduce such changes to your browsing program would be because the pesky app is trying to further push its agenda, which agenda typically is associated with online advertising.

Type Regedit in the windows search field and press Enter.

    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

After all, it should have been obvious by now – apps of this category are all about their adverts and the money they could generate through them. A good example of a software piece that can be regarded as a hijacker is the intrusive app. Many users complain about the nagging capabilities of this piece of software and since many of you might have come here in search of help against this app, we can offer you an effective way to remove it in the following guide.

The reason why you might need to use the removal guide or the security tool added to it is because it is normally not that easy to uninstall a hijacker the likes of Remember, the developers of need to ensure that their product stays on your PC for as long as possible so that the revenue they could gain from it would be maximized. Of course, you don’t really benefit from that in any way – quite the opposite. If an app like is on your machine, the only thing that you’d get from it is irritation and some potential security hazards. Now, here we are not talking about a nasty malware program – is no Trojan or Ransomware or some other similar malicious virus. However, if you aren’t careful around this app you might as well get your machine infected with some insidious Ransomware infection or a Trojan Horse program. The thing that is most problematic and potentially hazardous is, as you can imagine, the ads. The problem with the ads, the page-redirects, the banners and the pop-ups that may place on your screen is that some of them might be linked with shady sources and online addresses. The Internet is a great thing but could also be a dangerous place for your computer’s safety and there are indeed a lot of ads out there that could land you on unsafe sites and pages. That’s why, the advice we give all our readers is to use the provided guides on our site and use them to eliminate any potentially unwanted software before any actual problem has occurred.

Keeping the machine clean

Awareness while browsing is key when it comes to maintaining a safe and clean system. Naturally, anything suspicious such as spam, questionable adverts, offers and requests, pirated and illegal software or low-quality downloads, suspicious sites and pages and so on must be avoided. Another really important tip is to only install a new program after you have thoroughly explored and examined the setup manager and disabled any optional bundled software components that you might not want to have on your computer. Only after you do that would it be safe to continue with the installation knowing that no undesirable applications would get installed on your PC.
