Ever since its inception way back in June of 2016, its first significant change was it was able to create Google Chrome Profile. By doing this, it is able to run all of the user’s internet traffic through the fake profile and it is able to transfer some of the original content of the user from their legitimate profile to the fake one. In this way, the user is not able to change the browser’s settings to its original setup. What’s bad about this is that even if the new profile is deleted, it will come right back up whenever the browser is opened once again. In most cases, it is named “user0” and the icon will be grayed out instead of the regular blue color. If you happen to notice these changes, then you should definitely run a full system scan with your preferred anti-virus software.

In February of 2017, the cybercriminals behind the Youndoo Virus has once again updated the symptoms of the threat. It has started to create additional profiles in Firefox and names it “Firefox Default” and is now able to schedule tasks that run on its desired time. It can also download updates and reinstall the virus if the user attempts to remove it.
