What is Windows Interactive Security?

The Malwarebytes research team has determined that Windows Interactive Security is a fake anti-malware application. These so-called "rogues" use intentional false positives to convince users that their systems have been compromised. Then they try to sell you their software, claiming it will remove these threats. In extreme cases the false threats are actually the very trojans that advertise or even directly install the rogue. You are strongly advised to follow our removal instructions below.

How do I know if I am infected with Windows Interactive Security?

This is how the main screen of the rogue application looks:


You will find this icon in your taskbar:


And see these warnings:





How did Windows Interactive Security get on my computer?

Rogue programs use different methods for spreading themselves. This particular one was installed by a fake online scanner.

How do I remove Windows Interactive Security?

Our program Malwarebytes Anti-Malware can detect and remove this rogue application, but because this rogue blocks the normal use of programs we will use Chameleon to remove it.

  • If Malwarebytes Anti-Malware is not installed on the infected computer.
    In order for this to work, you could need a second PC which is not infected and a USB flash drive or blank CD and CD burner or some other means to transfer files from one computer to the other.
    1. Download Chameleon from the Malwarebytes site.
    2. Unzip the contents of the zip-file to a folder in a convenient location on the infected computer.
    3. If you were unable to do this directly on the infected PC, then copy the folder from the clean computer to the infected one.
    4. Make certain that your infected PC is connected to the internet and then open the folder you created or copied, on your infected computer and double-click on svchost.exe.
    5. Follow the onscreen instructions to press a key to continue and Chameleon will proceed to download and install Malwarebytes Anti-Malware for you.
    6. Once it has done this, it will attempt to update Malwarebytes Anti-Malware, click OK when it says that the database was updated successfully
    7. Next, Malwarebytes Anti-Malware will automatically open and perform a Quick scan
    8. Upon completion of the scan, if anything has been detected, click on Show Results
    9. Have Malwarebytes Anti-Malware remove any threats that are detected and click Yes if prompted to reboot your computer to allow the removal process to complete
    10. After your computer restarts, open Malwarebytes Anti-Malware and perform one last Quick scan to verify that there are no remaining threats

  • If Malwarebytes Anti-Malware is already installed on the infected computer.
    In order for this to work, you must already have Malwarebytes Anti-Malware version 1.60 or later already installed on your infected PC.
    1. Open the program folder for Malwarebytes Anti-Malware (normally C:\Program Files\Malwarebytes' Anti-Malware or C:\Program Files (x86)\Malwarebytes' Anti-Malware)
    2. Once there, open the Chameleon folder
    3. Next, double-click on svchost.exe. This should result in a black DOS/command prompt window opening up.
    4. Press any key to continue as it says in the window
    5. Malwarebytes Chameleon will proceed to update Malwarebytes Anti-Malware, so ensure that you are connected to the internet if possible
    6. Once the update completes and it says your database is updated, click on OK
    7. Malwarebytes Chameleon will then terminate any threats running in memory, which may take a while, so please be patient
    8. Upon completion, Malwarebytes Anti-Malware will open automatically and perform a Quick scan
    9. Once the scan is complete, click on Show Results and remove any threats that are found by clicking Remove Selected
    10. If prompted to restart your computer to complete the removal process, click Yes
    11. After your computer restarts, open Malwarebytes Anti-Malware and perform one last Quick scan to verify that there are no remaining threats

Below is what you can expect to see in the Command prompt after succesfully using Chameleon.
