Cookies On-Off Extension 1.0.1 Removal

In the text below we are talking about a program called Cookies On-Off Extension 1.0.1. Being classified as a browser hijacker, this software could function in the here explained way:

  • It may infect your computer with your unknowing permission and invade and modify your browser apps following that. Neither Explorer, nor Chrome and Firefox can be safe from this kind of software.;
  • The way it might alter your browsers is by setting them to redirect you to somewhere on the web: normally a website you have never needed to load.;
  • What’s more, such programs may cause the generation of a really big number of cyber ads in the form of banners and pop-ups while you are surfing the Internet.
  • Furthermore, Cookies On-Off Extension 1.0.1 may even take off the homepage and/or search engine you have set and may put (a) new one(s).

More info about browser hijackers in general, and this particular one, is ready to be read in the passages below. We really hope that our article is what you need to solve your hijacker-related annoyances.

Something more about browser hijackers:

Cookies On-Off Extension 1.0.1 and all its related programs can be regarded as NOT really dangerous. Still, all browser hijackers might at times have some really questionable features such as being able to get access to your browser data records and use the info from there to try to determine what kind of products you will be interested in. Following that, only the advertisements supposedly matching your tastes will get displayed. It is a simple marketing strategy, however,  a really effective one that could be seen as more or less intrusive. 

Also, the intensive broadcast of ads might perhaps slow down your device a bit. This possible negative effect depends on the resources of your computer and you are likely to never really experience it.

Is this program related to any malware type?

Luckily, there is no relation between hijackers and any malware of any kind. However, we need to make the considerable difference they have clearer. For this reason we will compare a Ransomware version and Cookies On-Off Extension 1.0.1:

  • Perhaps you already know much about the characteristics of Cookies On-Off Extension 1.0.1. A real virus normally functions in a DIFFERENT way. For example, if the virus is a Ransomware-based one, it will sneak into your PC, stay there and review your hard drives to determine which your most favourite files exactly are. When a detailed list containing all of these files gets ready, the Ransomware usually goes on with encoding them all. In this way you won’t be able to access them, and the Ransomware will display a notification, informing you your files have been rendered unavailable and you should pay a ransom in exchange for them. If compared to this malicious consequence, the Cookies On-Off Extension 1.0.1 effects indeed look quite harmless.

How you may have caught Cookies On-Off Extension 1.0.1

Despite these significant differences, the manners in which programmers may spread  hijackers are usually quite annoying and unclear, as you may unknowingly accept and authorise the installation of this advertising software. Surely, you won’t let such a program get installed on your PC if you are aware of just how much it could disturb you. Consequently, its programmers have found a way to spread it without clearly saying it is there and you might catch it because of that. For distributing ad-causing programs such as hijackers, programmers have come up with the idea to make their sources seem very tempting. This is why program bundles have appeared – they represent tempting free software sets that may contain all kinds of programs that may seem especially interesting to you. Nevertheless, it is not the download of such a bundle that matters, it is the installation process that does.

How to install a bundle but avoid the potential hijacker inside it?

The most typical mistake you might make that will certainly cause the infection with Cookies On-Off Extension 1.0.1 is to install the wanted piece of software or bundle in one of the following steps:

  • Automatic; Default; Recommended:
    These features describe the process of automatic installation of the WHOLE CONTENT OF A BUNDLE or ALL THE FEATURES OF ANY PROGRAM. Basically, this means that all kinds of infections are probable, as well as some undesired changes to your PC may occur.
  • To stay away from the unwanted effects explained above, please, select the Customized or the Advanced installation options. If you do that you will always have the word when it comes to what is supposed and is not supposed to be installed.
