TeamViewer is a remote control software primarily used to establish a connection to any PC or server around the world. The software, designed to conduct PC screen sharing & control activities and online meetings, encounters the following error:
No connection to TeamViewer server. Kaspersky Internet Security has been found on this computer, this software may be blocking TeamViewer’s access to the Internet.
As the error clearly describes, an Antivirus installed on your computer might have triggered a false positive resulting into blocking of network connections and traffic to the computers/ servers you’re trying to connect. The solution is simple: add TeamViewer to exclusions, mark the application as a trusted app, or temporarily disable your Antivirus.
