How to remove Win32:KadrBot

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

  3. Select Win32:KadrBot from the list and click on Uninstall.
  4. Follow the steps in the removal wizard.

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 Win32:KadrBot.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to Win32:KadrBot.
  • 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.

  1. Click on the three dots in the right upper corner

  • 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.

  2. From the menu, click on the Add-ons button.

If using Firefox:

  • 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.

How to Delete Win32:KadrBot

  1. Open task manager

  • If you don’t see a “Win32:KadrBot” 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

    How badly can a Trojan like Win32:KadrBot damage your system?

    A Trojan like Win32:KadrBot can launch a whole list of malicious activities on your machine and you may not even know about them until the harmful consequences appear. This is exactly why we urge all the users who have been infected with this type of malware to take immediate actions and to remove it as soon as possible. As one of the newest representatives of the Trojan Horse malware category, Win32:KadrBot could be programmed to perform quite harmful and malicious targeted attacks. For instance, the hackers who have control over it may try to program it to secretly keep tabs on your online and offline activities and copy your passwords, banking data and online login credentials so that the hackers could get their hands on them. They may also use the malware for espionage purposes and hack into your mic or webcam without your knowledge and use any private data and footage of you for the purposes of blackmailing and personal harassment. Win32:KadrBot may also operate as a backdoor for other viruses (such as Ransomware or Rootkits) and weaken your system by blocking the Firewall or the antivirus program. That’s why, the sooner you manage to detect and remove it, the greater the chances of saving your computer from and potentially irreparable damage.
