Baidu Browser

I just opened Google Chrome for the first time after allowing some Windows Updates, not adding any other new software (as far as I am aware) and Baidu Browser started loading and was over the top of my Chrome install. I could close Baidu & chrome was happily still there and operating as expected. How do I entirely remove Baidu, or do I not need to be worried about it at all?

 

Tanks in advance
