If all of your browser apps have began the production of more ads (pop-ups/ banners) than you can bear; or their default homepages and search engines have been substituted with some new ones; and if your browsers have started to redirect you to unknown web pages, it is very probable that your system has been infected by a version of a  browser hijacker. More precisely, its name is, and it might affect and modify all of the most common browsers: Chrome, Explorer, Opera or Firefox, and the less popular ones as well.

What do we mean by “a browser hijacker”?

All of the browser hijackers we know about are actually programs that have all the traits, mentioned above. Each one of them could be able to modify the settings and the appearance of your browser apps. This possible outcome may incredibly annoy you – the whole ad flow or the change of your default homepage/ search engine may also be quite irritating. The possible redirecting processes that result from the contamination with “Malware” may really be very bothering, especially because the distributed web pages might be absolutely unfamiliar or may appear very suspicious to you. In addition, you may not at all like the newly set homepages and/or search engines your browser apps might now have. In general, the way in which such a hijacker could affect your PC may be harmless. Nonetheless, you might feel the awful annoyance as a result of all that follows from such an infection.

Has ever been considered a version of malware?

As a standard browser hijacker, this program has never been classified as malware or a virus at all. For example, any common representative of Ransomware is really able to self-install on your PC, and later on access your disks and drives and encrypt all the essential files on them. Such malicious effects are impossible when it comes to an infection caused by a program like Yet, most browser hijackers are so incredibly annoying – could they in any way also be harmful?

All the irritating changes might lead to are legitimate, and will typically not result in any actual harm to you or your device. Its creators have programmed all hijackers to simply promote new homepages, search engines, products, services, etc. The simple activity of advertising anything is not malicious, nor has it ever been illegal. Nonetheless, the stream of pop-ups and banners may indeed be overwhelming you while you’re surfing the Internet. Despite that, none of these actions are even close to what the really malicious threats can do. Actually, the real reason why developers create browser hijackers is for the purpose of promoting services and products, which in turn earns them a nice profit.  

If is not a real virus, how has your PC ended up contaminated? might come from many different sources. All torrents or shareware-distributing websites may have it integrated into them, and once you load or download anything like that, you might give your unknowing permission to get installed on your device. Moreover, it might be lurking inside the famous program bundles. However, the act of downloading a bundle cannot infect your PC with an ad-producing piece. Getting it installed in an improper or careless manner, however, may leave you infected.

What is ‘a program bundle’? The proper way to install such a software mix:

Generally speaking, a software bundle is the mixture of a number of different free programs (apps/games), distributed as a whole, usually for free on the Internet. The only truly sensible way of having such a bundle installed on your PC (or any of its components, or any other program you download from somewhere), is on no condition to ever give your (knowing or unknowing) approval for the whole content of such a mixture to get installed into your system. The only sensible installation feature which provides the opportunity to opt in and out of any component of a given bundle and the corresponding undesired features of any software is the Customized one (also labeled as Advanced). Always go for it for the safe completion of any ongoing installation process. In this way you will keep your system free from dangers far greater than hijackers even.
