This page aims to help you remove Cookies On-Off Extension 1.0.1. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Cookies On-Off Extension 1.0.1 is a browser hijacking program, which may cause you a lot of browsing disturbance. Do not panic – the program is not destructive and will not damage your personal data or your system in any way, unlike a real virus or a Trojan-Ransomware threat for example. The reason to remove Cookies On-Off Extension 1.0.1 from your computer is different and is related to the advertising strategies the program uses to make money from its services. What we have in mind here is the aggressive stream of ads, banners, and pop-ups that it can generate and the potential changes (homepage or search engine replacements, new toolbar installations) it may impose to your Chrome, Firefox or Explorer browser. Let us tell you more about that in the next lines.

I have not installed the program. How did it appear on my computer?

Cookies On-Off Extension 1.0.1 is a program that does not require special conditions or some vulnerability to enter your system. In fact, this hijacker just needs you to download and install a software package or a free installer that contains its installation files. This program could be bundled inside of different automatic setups, free application installers, software packages, spam emails and attachments, torrents or free download links. That’s why, the moment you have to run a given installer, you should always opt for the most detailed installation procedure and customize it via the “Advanced” or the “Manual” option. If you skip that, some potentially unwanted programs may become part of your system as part of the software package. Not to mention that many unpleasant viruses that spread across the web and can do much more damage may also use such an approach to sneak inside your system. So our advice is to always stay away from unreliable sources for downloading software and carefully check what you are installing on your computer.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

  1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
  2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
  3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.



  • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.

Right click on the browser’s shortcut —> Properties.

NOTE: We are showing Google Chrome, but you can do this for Firefox and IE (or Edge).

Cookies On-Off Extension 1.0.1 – a tool that displays ads for profit?

Naturally, there is nothing really free on the web and the authors of different programs and tools either charge for their software product or try to make money using other techniques such as the pay-per-click or PPC in short. This method is well known among legitimate software developers, but some of them are so enthusiastic about it, that they often forget about the very functionality of their service and focus on displaying ads for profits. Unfortunately, that’s what has happened to Cookies On-Off Extension 1.0.1. This program operates as a browser hijacker and can literally fill the users’ screen with various sponsored links. It may also redirect their search results to some ads, sponsored sites and intrusive offers and prompt them to click on them. A lot of users, who have faced this program, are reporting that they have issues browsing the web normally and using their affected browser due to this activity. But is Cookies On-Off Extension 1.0.1 really such a disturbance and can it cause more harm? Let’s find out.

Why is it a good idea to uninstall this hijacker from your computer?

If Cookies On-Off Extension 1.0.1 has hijacked your default browser and is causing you irritation, the first thing you probably tried to do is to reset the original browser settings. Unfortunately, this may not be possible because the annoying program continues to appear in the browser and keeps displaying its ads regardless of your efforts to remove them. At this point, many people think that they have been infected with some nasty virus or some other malware like a Trojan or Ransomware based infection, and tend to get panicked because they feel helpless to eliminate the program and the disturbance it is causing them. However, many users don’t know that what they are facing is typical behavior of a browser hijacker, not a malicious virus.

Programs like Cookies On-Off Extension 1.0.1 usually are not considered as harmful but they are able to remain in your system thanks to some components (such as toolbars, plug-ins and browser extensions) that they install deep inside your system and prevent the easy removal of the hijacker. Of course, when these components start to operate and generate ads, redirect your searches and flood your screen with nagging pop-ups, they may expose you to sketchy content that you may not want to interact with, or even to some insecure web locations where security hazards may be lurking. You can also assume that these additional processes will definitely not speed up the browser’s performance and may, in fact, cause some sluggishness, screen freezing, more often crashes and browsing interruptions. For these reasons, many of you may eventually decide to uninstall Cookies On-Off Extension 1.0.1. Due to the location of the browser hijacking components in the system, however, you may think that the hijacker can be difficult to remove. But do not worry, you can trust the instructions in the removal guide below as they can fix everything for you. Just follow them strictly and your PC will soon be free from the browser hijacker and its disturbance.
