Hi all

I have a Windows Domain with all clients Windows 8.1 and Kaspersky Security Center 12 installed in a server and distributed by agent.

In a workstation I have 3 installed browser: Chrome, Firefox and Edge.

Firefox and Edge haven’t trouble while Chrome get “Err_connection_reset”.

Disabling Kaspersky, Chrome is working again and if I re-enable Kaspersky Chrome doesn’t work.


What I can check?
