I have recently installed kaspersky internet security from official website some 1.5 weeks ago. So, I am pretty sure, it's the most latest version.

Hello,

It looks like an actual attack which has been blocked, so you have nothing to worry about. Kaspersky is doing its job protecting you.

To verify that it is not a false detection, we would need traces and network logs submitted to technical support via my.kaspersky.com.

Hello,

Please see the following screenshot. just un-check Internet Protocol Version 6 (TCP/IPv6). I don’t know your network whether is based on IPv6 or not. In my side, My network is based on IPv4 now. If you encounter some network problem after disabled ipv6 support, Please turn the settings back.

This network threat is not hindered by network protocols. IPv4 is more mature than IPv6. It's that simple.

I have one more problem that the anti banner module is not blocking youtube ads in every browsers. Sometimes it gets blocked. Maybe it’s triggering anti banner lately. This issue is happening after .391(b) update.
