ChatSAI belongs to the class of software more commonly referred to as browser hijackers. As such, ChatSAI infects the browser on your computer and takes charge of it by altering some of its settings.

The ChatSAI Virus will redirect your searches

As a result, users start being plagued by swarms of online ads in every shape and size. These can be banners, popups, in-text links, box messages and various other forms of online advertising materials. In addition, your browser may start to trigger page redirects that take you to different obscure web locations.

The ChatSAI Virus

On top of that, the ChatSAI virus may replace your default search engine with a different one. And very often the ChatSAI virus will also set this new search engine as the browser homepage, as well.

This ensures, on the one hand, that you are exposed to more sponsored search results. And on the other hand, the website in question gets more hits and a higher traffic count, which is quite possibly what the hijacker developers are paid for.

If you try and reset these browser configurations, you will notice that they return back to what the hijacker has determined them to be – no matter what you do. Even reinstalling your browser or switching to a different one will only offer temporary relief before ChatSAI gets integrated as well. And as it so happens, programs like ChatSAI, Shampoo are equally sticky themselves, when it comes to their uninstallation.

You will find that most of them do not offer an uninstallation option the way that regular software products do. And if you try to somehow remove it yourself without fully understanding what you’re dealing with, chances are you won’t find all of the components, and its residual parts may still cause issues during your browsing sessions. This is why our team of experts has put together a detailed removal guide that you can find below.

How to remove ChatSAI

  1. First, click the Start Menu on your Windows PC.

  3. Select ChatSAI from the list and click on Uninstall.
  4. Follow the steps in the removal wizard.

If you have a Mac virus, please use our How to remove Ads on Mac guide.

If you have an Android virus, please use our Android Malware Removal guide.

If you have an iPhone virus, please use our iPhone Virus Removal guide.

What we suggest you do first is, check the list of programs that are presently installed on the infected device and uninstall any rogue software that you find there:

  • From the Start Menu, navigate to Control Panel ->>> Programs and Features ->>> Uninstall a Program.
  • Next, carefully search for unfamiliar programs or programs that have been installed recently and could be related to ChatSAI.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to ChatSAI.
  • If a notification appears on your screen when you try to uninstall a specific questionable program prompting you to just alter it or repair it, make sure you choose NO and complete the steps from the removal wizard.

Remove ChatSAI from Chrome

  1. Click on the three dots in the right upper corner
  2. Go to more tools
  3. Now select extensions
  4. Remove the ChatSAI extension
  • Once you open Chrome, click on the three-dots icon to open the browser’s menu, go to More Tools/ More Options, and then to Extensions.
  • Again, find the items on that page that could be linked to ChatSAI and/or that might be causing problems in the browser and delete them.
  • Afterwards, go to this folder: Computer > C: > Users > *Your User Account* > App Data > Local > Google > Chrome > User Data. In there, you will find a folder named Default – you should change its name to Backup Default and restart the PC.
  • Note that the App Data folder is normally hidden so you’d have to first make the hidden files and folders on your PC visible before you can access it.

How to get rid of ChatSAI on FF/Edge/etc.

  1. Open the browser and select the menu icon.
  2. From the menu, click on the Add-ons button.
  3. Look for the ChatSAI extension
  4. Get rid of ChatSAI by removing it from extensions

If using Firefox:

  • Open Firefox
  • Select the three parallel lines menu and go to Add-ons.
  • Find the unwanted add-on and delete it from the browser – if there is more than one unwanted extension, remove all of them.
  • Go to the browser menu again, select Options, and then click on Home from the sidebar to the left.
  • Check the current addresses for the browser’s homepage and new-tab page and change them if they are currently set to address(es) you don’t know or trust.

If using MS Edge/IE:

  • Start Edge
  • Select the browser menu and go to Extensions.
  • Find and uninstall any Edge extensions that look undesirable and unwanted.
  • Select Settings from the browser menu and click on Appearance.
  • Check the new-tab page address of the browser and if it has been modified by “ChatSAI” or another unwanted app, change it to an address that you’d want to be the browser’s new-tab page.

How to Delete ChatSAI

  1. Open task manager
  2. Look for the ChatSAI process
  3. Select it and click on End task
  4. Open the file location to delete ChatSAI
  • Access the Task Manager by pressing together the Ctrl + Alt + Del keys and then selecting Task Manager.
  • Open Processes and there try to find a process with the name of the unwanted software. If you find it, select it with the right button of the mouse and click on the Open File Location option.
  • If you don’t see a “ChatSAI” process in the Task Manager, look for another suspicious process with an unusual name. It is likely that the unwanted process would be using lots of RAM and CPU so pay attention to the number of resources each process is using.
  • Tip: If you think you have singled out the unwanted process but are not sure, it’s always a good idea to search for information about it on the Internet – this should give you a general idea if the process is a legitimate one from a regular program or from your OS or if it is indeed likely linked to the adware.
  • If you find another suspicious process, open its File Location too.
  • Once in the File Location folder for the suspicious process, start testing all of the files that are stored there by dragging them to our free online scanner available below.
  • Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
    This scanner is free and will always remain free for our website's users.
    This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    • If the scanner finds malware in any of the files, return to the Processes tab in the Task Manager, select the suspected process, and then select the End Process option to quit it.
    • Go back to the folder where the files of that process are located and delete all of the files that you are allowed to delete. If all files get deleted normally, exit the folder and delete that folder too. If one or more of the files showed an error message when you tried to delete them, leave them for now and return to try to delete them again once you’ve completed the rest of the guide.

    How to Uninstall ChatSAI

    1. Click on the home button
    2. Search for Startup Apps
    3. Look for ChatSAI in there
    4. Uninstall ChatSAI from Startup Apps by turning it off
    • Now you need to carefully search for and uninstall any ChatSAI-related entries from the Registry. The easiest way to do this is to open the Registry Editor app (type Regedit in the windows search field and press Enter) and then open a Find dialog (CTRL+F key combination) where you have to type the name of the threat. 
    • Perform a search by clicking on the Find Next button and delete any detected results. Do this as many times as needed until no more results are found. 
    • After that, to ensure that there are no remaining entries lined to ChatSAI in the Registry, go manually to the following directories and delete them:
    • HKEY_CURRENT_USER/Software/Random Directory. 
    • HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run/Random
    • HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main/Random

    What is ChatSAI?

    Yes, you’ve already come to experience all the annoying consequences of having a browser hijacker in your system. But what you may not know about these program is that they may be silently monitoring your browsing patterns and collecting this data to optimize the display of their ads. This is done so that the ads generated on your screen are more appealing to you and you will, ideally, be more prone to interact with them. That way ChatSAI can generate profit for its developers.
    However, this data may be sold to third parties for various intents and purposes – without your knowledge or consent. And on top of that, this background activity does take its toll on your system resources, which can be quite detrimental to your computer’s performance in the long run.
    Last but not least, seeing as the quantities of generated ads and page redirects are so vast, nobody really keeps track or checks their safety. Hence, there’s a risk of at some point landing on an unsafe webpage or clicking on some infected or compromised ad or link. And as a result, you may come face to face with ransomware, Trojan horse viruses and other malicious code.
