After uninstalling, there will still be two residual dll files in the program file of drive C, which cannot be deleted, and the boot will start automatically. This is where your partner is despised! ! What should we do at this time? We can change the name of this Baidu file in c:\program files\Baidu, and change it at will. Remember, you can't change the name of the folder before uninstalling! ! ! After adding a name to the file, the program running in the background can't find the dll file, so we can happily delete the folder Baidu and the two dll files inside! !
