What is com.facebook.katana? Should I remove it
on Windows

Hello. I am seeing this com.facebook.katana all the time on my phone. What is it? Is that a piece of the Facebook application or a virus? Should I leave it or can I remove it? Maybe there is something wrong with my phone and I should fix it because I encounter some pop-ups about this folder or file on the device?

The question of what is com.facebook.katana can come to many Android users because there are some folders on the system like this one and there is no particular information on what it might do on the device. Some people even receive pop-ups,[ref en-1] and cannot know what to do next. There is no need to panic and think about serious damage that the program or file can cause. This is not a malicious piece. 

You can find other filters like com.facebook.katana, and both com.facebook.orca and com.facebook.home are needed pieces of the Facebook mobile application and Facebook Messenger app.[ref en-2] There some instances when these folders appear in alerts and continue to pop-up on the screen out of nowhere. 

com.facebook.katana is the code name for the Facebook app on Android devices, orca is for the Messenger application. You do not need to remove these files if you want to keep using the program. However, when you installed the program yourself, you can uninstall it alongside these folders. When the app comes pre-installed, you can only disable it.

We should go back. What is com.facebook.katana? Should you remove it? This is not a virus and the name of the directory is not generates by a virus, as some dubious sources may claim. This package is automatically generated by the Facebook application once the program is installed. It should disappear once the program is uninstalled.

These folders hold all the data and programming files. There is no point of removing the katana file. But the only way to remove it is by uninstalling the application completely.
