I've been using Kaspersky for a few years now. Since around roughly 1 (2018) year ago, I began experiencing a complete cutoff from the internet. At first, I didn't realize it was Kaspersky that was doing it, but thought there was a problem with my computer itself. When this happens, I cannot open or load any new web pages, or refresh currently open web pages. When I try, absolutely nothing happens. I don't even get an error saying that that Firefox (or other browser) cannot find that site. LITERALLY NOTHING happens. I click the refresh button, or press ENTER after typing the URL or entering search parameters in the browser's search field, and NOTHING happens at all.

I proved it was Kaspersky that was cutting off internet access by completely exiting Kaspersky, so that it was completely shut down. As soon as I did, I was once again able to access the internet normally. I have since repeated this process over a dozen times with the exact same result. Once disabling Kaspersky and getting pages to load, I can immediately turn Kaspersky back on, and the internet remains accessible for a short time, before my access is once again lost. I can repeat this process only 2 or 3 times before the disabling of Kaspersky fails to restore acesss, and I have to reboot my PC in order to restore internet access.

You can try to close the Kaspersky Firewall module to test if you can connect to the Internet.
Or you can update the network driver, this may help you!

Also , and in addition to above suggestion from xiongliangchen_CN :

Your Windows Event Log is displaying following message :
"Name resolution for the name my.kaspersky.com timed out after none of the configured DNS servers responded."

> Can you please run "services.msc" and check if "DNS Client" is running + reboot
> Also , please power off your Router and restart after a couple of minutes

If no fix please contact Technical Support https://center.kaspersky.com
