How to clear the browser's plugin

Hello! I recently installed some software, did not pay much attention to the options when installing, now I found that there are several search engines (Baidu search, etc.) in my network toolbar, I feel very uncomfortable, I want to delete them, please Dong The master taught me a method. Thank you!

The easiest way is to go to www.360.cn to download a 360 security guard, use it to "clean up the bad comment plugin function, to delete these things. However, most will not appear in the "bad comment plugin," but in the "Other plugins." You check the plugin you want to delete, and then click the “Clear button now” to delete it easily!
