Cookies On-Off Extension Chrome Removal


Welcome to our Cookies On-Off Extension removal guide. The following instructions will aid you in removing the unwanted software from your PC.

What is Cookies On-Off Extension?

Cookies On-Off Extension is an online advertising tool, belonging to the browser hijacking category. Programs that belong to this category can be downloaded and installed on all of your browsers (such as Chrome, Firefox, Explorer, etc.) without knowing it because they are distributed primarily through software packages or so-called “bundles”. Typically, this suspected spreading method is performed with the help of title managers, PDF crawlers, video streaming software, and similar free programs that are marked as “extra components” in some free software installers. Note that these components can only be denied if you pay special attention to the software’s installation process and cancel the checkboxes that have automatically been marked for you to agree to install them. If you already have Cookies On-Off Extension on your system and it keeps bugging your browsing with constant page redirects, ads, intrusive banners and pop-ups, on this page we have a removal guide, which can help you safely uninstall this browser hijacker and have all of its related messages removed. In case that your browser’s homepage or search engine has also been replaced and doesn’t want to go away, the instructions below will help you permanently uninstall it and restore your favorite browser settings.

What issues may Cookies On-Off Extension cause to your system?

Once your browser has been hijacked by a program like Cookies On-Off Extension, your system may start displaying an abnormal amount of pop-up ads during each and every search session. In addition, this program may begin to monitor your browsing queries, and start collecting information related to your browsing preferences such as searches, most visited sites, the information you enter when you visit these sites, IP address and location of your computer. This information is considered to be personal non-identifying information, but its collection and usage by third parties may result in increased spam disturbance and exposure to more nagging ads. The people who benefit from collecting it are usually marketers, vendors and online advertisers, who try to use this information to target the displayed ads more precisely and to redirect you to sites and offers that correspond to your searches. This way, they can benefit from your clicks and get remunerated for them thanks to methods like Pay-Per-Click or some paid advertisement positioning.

Such activity is generally seen as a common online advertising practice, which, despite being invasive, is not considered harmful to your system. It cannot be accused of some malicious deeds like data corruption, spying, online fraud or theft, which are typical for the normal viruses and harmful threats like Trojan horses, Ransomware and Spyware. Still, if not malicious, the browser hijacker’s behavior may eventually be a source of browsing disturbance for some users. If you think you are one of those users, whose normal web activity has been interrupted by Cookies On-Off Extension or a similar program, having it removed may be the only permanent solution for you. Feel free to use the instructions in the removal guide below in order to identify the right components and safely delete them from your system.

How can you prevent Cookies On-Off Extension from becoming part of your system?

If your web browser redirects you to unknown sites or shows you different pop-up ads during browsing, it means that a browser hacker is hidden in your system. As we have already mentioned in the beginning of this article, such potentially unwanted software is actively spreading through software packages. Luckily, you don’t have to stop using free programs to protect yourself from browser hijackers like Cookies On-Off Extension. To prevent them from getting installed, you should use the following tips:

  • When choosing a free program, make sure you have read the privacy policy and the license agreement. If tracking browser behavior, ad content, and similar things are mentioned, you should look for a different software installer.
  • If you have the intention to install a new program, make sure that you do not click on the Quick, Basic, or Recommended installation. Select the Manual or Detailed installation instead and customize the installer.
  • Be very careful during the installation process and read what is written in each of the windows. If you see a highlighted field that allows changes to the homepage or the default search engine, you need to unmark it. You should also reject suggestions to install unknown browser components, extensions, and plugins.
  • Install reliable anti-spyware software and keep it up-to-date. This will help you avoid not only browser hijackers, but also nasty viruses and much more serious infections like Trojans and Ransomware, which may hide deep into the software bundles.
