If your internet connection is not working correctly, try to connect to the update server. Also, it might be possible that you have blocked the link to the update server. Go to the TrustPort Center and check your settings to resolve this issue. If you use a proxy server, ensure it is set up correctly in TrustPort Antivirus Download. In the system tray, click the Update item and select the proxy server. If you are a proxy server user, you can log in to it by entering the server's IP address. You will need to enter a username and password if it requires authentication.
