4. Why can’t I log onto Institutional Internet Banking after installing the WINDOWS update patch?

This is probably because you have installed the Microsoft Windows KB977377 Patch: (a workaround that server administrators can install to disable TLS and SSL renegotiation). According to the announcement for the KB977377 Patch published on Microsoft website, the download of the patch is recommended for server administrators only, and it is unnecessary for other users to install it. We recommend that you install patches with 360. You should only install patches for serious loopholes suggested by 360, and ignore optional patches or those patches that are not recommended. If you have already installed this patch, please use the Add/Remove Program in the Windows Operating System to remove the patch and then reboot your computer.
