Select Tools-Internet Options-Security-Internet-Custom Level in the IE browser menu, and select Reset to Security Level-Medium in the dialog box. Click Reset and confirm. Please note that Download Signed ActiveX Controls and Run ActiveX Controls and Plug-ins must be enabled. After setting IE browser successfully, please click the link "Please download and install security controls for the first time login" on the online banking login page to download and install online banking security controls. In addition, if you install software such as Internet Assistant that prohibits the installation and operation of the control, please modify its corresponding settings so that the control can be installed and used normally.
