How to clean up the unsafe software called “Babylon”


I cleaned up “Babylon” software because there was the request for deletion. As a result of the operation, I felt that it is difficult to prevent from it. 

Therefore, I would like to explain how to clean up it and do the tentative preventive measures. The Office  continues to test about the steps. 

Is Babylon software threat?

I cannot allege that it’s the threat because I could not get the sure information. (the information was reported in some blogs that it served as a spyware, but they cannot be verified. 

However, at least, I can say, “The software involves an unwanted function” because it is very hard to remove the software. Moreover, the software try to install to a PC without the user’s acceptant or it tries to camouflage the installation. I think that it is very serious issue because the approaches are adware or spyware.

Do you know what happen when Babylon was installed?

I don’t know about the detail information, but at least, the web browsers in your PC will be forcibly overwritten for always running Babylon system even if you change the settings or remove Babylon software.  Concretely, the following activities were reported.

  • Create the Babylon toolbar in a web browser and a user cannot remove it.
  • The search engine in a web browser is changed to Babylon.
  • Startup page of a web browser changes to Babylon web site and a user cannot change the page setting.

* Even if you remove Babylon software, the Babylon system will continue alive.

Where does Babylon come from?

Basically, it seems that free softwares involve Babylon. Therefore, when a user installs a free software, the possibility to be installed is high. Especially, Babylon is automatically installed without the user’s acceptance. I think that it is very important issue.
