Pls.tell me how can I update kaspersky antivirus without connecting to the Internet?

Well, you could manually download the update (with the internet), and then install it by double-clicking it (and hopefully you don't need the internet for this).

Hope this helps.
You will need to connect to the internet to download the updates, but then you can disconnect.
