Remove Cwasre Virus


The following article will point out to you what the characteristics of a program called Cwasre Virus are, and how to remove the infection this kind of software may cause. Briefly speaking, this program is a member of a very widely-spread software group called browser hijackers. Among their distinctive features are accessing your browser apps (like Explorer/ Chrome/ Firefox/ Opera), modifying their settings and making them:

  • display a huge number of sometimes irritating ads in the form of boxes, pop-ups and banners;
  • put completely unknown homepages and search engines;
  • redirect you to a variety of websites, which you have never wanted to load, while you are trying to browse the Internet.

Typically, such programs are more or less harmless. What else you should expect when it comes to hijackers and how to successfully deal with them are matters, thoroughly discussed in the text below.

How such programs may act:

As we have explained in the paragraph above, hijackers could only infect and change the settings of all your browsers. Whatever browser you are using, you can expect redirecting, ad production and homepage/ search engine substituting. Such software is entirely promotion-oriented.

How such a program may come to your PC:

The usual sources of browser hijackers are the following:

  • Torrents and shareware: Hijackers may come from torrents and shareware, which means that no torrent is safe. Our advice for you is to simply avoid all of them.
  • Contagious websites: This is another popular source, as any browser hijacker may infect your computer in case you unintentionally click on a pop-up, produced by a contagious website.
  • The process ‘Program bundling’: This process involves the spreading of numerous programs/ games/ apps together inside program bundles. Normally, such mixes of software are available for free and anyone could access them. What you should definitely know about this way of distributing Cwasre Virus is that:
    – the simple act of downloading a wanted bundle will not infect your computer with a hijacker;
    – however, installing the bundle in a quick and often – careless, way almost always means getting infected with promotion-oriented programs such as Adware and hijacker-based ones.

How to avoid the hijackers/ Adware from the inside of a bundle, in case we really want to try another program from it?

It is not that hard to develop some proper habits when it comes to installing various kinds of software. What you need to do is to stay away from all the wizard steps promising you a quick and automatically-performed installation process. Usually, choosing such an ‘easy’ feature can deprive you of the chance to select the exact programs from a bundle, or the exact features of a program, which you indeed need on your system. The following installation features are to be always avoided: the Default/ the Recommended/ the Typical/ the Easy/ the Quick one. Instead, you should use the Customized (often called the Advanced) feature, which as its name implies, will let you customize the entire installation process. Thus, the last word will be yours when it comes to the wanted features and programs. Choose wisely, always go with these wizards options.

Why are they developed?

Perhaps you are thinking about the reason why such software has been developed in the first place. Nonetheless, it does not come as a shock at all as hijackers are exploited for advertising purposes. This means that all their features serve the marketing industry and the possible redirecting and ad production are only the results from the desire of manufacturers to have their products promoted; and of the web developers to earn some additional profits.

Why are they considered harmless most of the time?

In general, browser hijackers are normal harmless advertising products, which are considered potentially unwanted due to the possible redirecting and ad generation that they may cause. Nevertheless, they are still considered more or less harmless, as compared to the actual viruses, like the ones based on Ransomware, they do not have anything in common and cannot cause nearly as much trouble. As an illustration – if your system has been infected with Ransomware, all your data will face encryption and even destruction. In the case of contamination with Cwasre Virus, only your browsers could face some slight, yet annoying modifications. We have explained them above. What’s more, the Ransomware viruses will NEVER have to ask you for your permission to get installed they do that in an automatic way, while the developers of hijackers are always looking for a way to trick you into approving the installation of Cwasre Virus, for instance.
