If a browser hijacker has managed to get installed on your PC and added to your Chrome, IE or Firefox browser (or any other browser you might have on your machine), then you are likely experiencing significant browsing disturbance caused by certain changes made to your browser as well as intrusive generation of unpleasant and irritating web-ads and page redirects. Among the most common browser changes that hijackers tend to cause are a replacement of the default search engine, new-tab page and homepage as well as the integration of a new toolbar that gets added to the browsing program. Recently, a big number of users have reported that a browser add-on called Defpush.com “Virus” has gotten inside their PC and has started to behave in a way reminiscent of browser hijackers – it has altered the appearance and functionality of their browsing programs and it has been triggering unwanted redirects to random sponsored sites as well as showing obstructive advertising content over the browser’s screen.

Concerning Defpush.com and other hijackers

Even if you currently have this irritating browser redirect on your PC and are anxious to have it removed ASAP, we still advise you to take a couple more minutes in order to read the remainder of this post prior to actually beginning to use the guide. With any type of unwanted software, it is important to be well aware of its characteristics so that you know what you are dealing with. In this case, Defpush.com, for the most part, isn’t actually a harmful piece of software. It isn’t some sort of malware virus like a Trojan, a Worm or a Ransomware – instead, hijackers like this one are primarily harmless and as far as your PC system and virtual security are concerned. In reality, the main purpose of such browser add-ons that try to modify your browsing programs and redirect you to different pages is generating revenue by advertising different sites, software programs, web services, etc. The creators of hijackers like Defpush.com typically get financially compensated through models such as Pay-Per-Click and Pay-Per-View for displaying ads and promoting various types of products. Obviously, this is the whole reason behind the browsing disturbance you might have been experiencing lately – it’s normally nothing more than an overly-aggressive advertising campaign that is being carried out by the hijacker’s creators.

Why you’d better get rid of the browser redirect

It should be obvious by now that there’s pretty much nothing that you can gain from such a hijacker. Of course, there are instances where such browser add-ons do offer the user some functional and helpful feature, yet, in most cases, the intrusiveness that comes from the ad-generation, the page redirects and the unpleasant browser modifications is just too much and vastly outweighs any potential positive traits that such a browser-redirect might have to offer. Aside from that, though, as we mentioned already, hijackers aren’t typically dangerous, they could still sometimes lower the overall protection of your PC due to some of the modifications they make to your browsers and Internet settings. This is why, if you want to keep your machine well protected against noxious and highly-dangerous threats like Trojan Horses, Rootkits, Ransomware and Spyware, we advise you to remove Defpush.com from your machine as soon as you finish reading this article.

Do not allow hijackers inside your system in future

One of the most popular and successful methods for spreading such page-redirecting browser extensions are the so-called file bundles where the hijacker gets put inside another program’s installer. Typically, if you install a program that has other applications bundled to it using the Default/Quick setup configuration, the added software would get installed by default. This is why, you must always go for the Custom setup settings and manually choose what to allow in your PC and what to leave out. Another very important piece of advice when it comes to preventing the installation of hijackers is to avoid suspicious-looking ads, spam messages, misleading web offers and update requests, pirated and illegal software downloads as well as any other form of unreliable-looking online content.
