Com.yhn4621.ujm0317 is a browser hijacker for smartphones and tablets with the Android OS, and it is known for its aggressive site-redirects and pop-up messages. Com.yhn4621.ujm0317 will not stop showing ads on your display and lockscreen until you uninstall it from the device.

Generally, software like Com.yhn4621.ujm0317 is unable to damage the device you are using, but it can have negative effects on its security that could eventually lead to attacks from more hazardous software like Trojans or Ransomware. The main problem with Android hijackers is that they gain a wide range of privileges and permissions on the device without the user realizing it, and they could use those permissions to spam you with automatic page-redirects, misleading banners/pop-ups, and other forms of aggressive promotional content. They could also make changes in the default browser of the device as well as in browsers like Chrome or Firefox.

One additional problem with Com.yhn4621.ujm0317 and other similar software is that it tends to gather data from your device and send it to third-parties who will use it for undisclosed purposes. Obviously, in most cases its all about targeted advertising but since you are never explicitly told what data will be gathered from your device or how said data will be used, it is not a good idea to trust Com.yhn4621.ujm0317 or allow it to stay on the device.

Hopefully, with the help of the quick removal guide posted below, you will be able to clear your smartphone from Com.yhn4621.ujm0317 and bring its browser and Internet settings back to their normal state.

• Important!

If you are still seeing Ads in your browser, it is likely they are generated by the websites you visit and there is nothing you can do about it.

However, if you are seeing Adverts outside of your internet browser, then one of your installed Apps contains the problematic Adware. In this case you need to take a look at this guide.
