Uc always pops up unhealthy.

Just turn off the pop-up screen in the settings. If you can't solve it, you can try reinstalling the browser or cleaning up the cache. It is inevitable to kill the virus without poisoning. Today's browsers are all like this. When you open them, many advertisements will pop up, which is very annoying. Otherwise, please try another browser. I have been using QQ browser. Just turn off the settings of this pop-up window, which is quite convenient. It also has the function of walking around and filtering advertisements, making the internet quieter and safer!
