My story is :
I updated a website’s content through a windows computer with Kaspersky antivirus enabled on it, I didn’t care much.
I accessed that site’s Cpanel and was updating through the file manager. And later, my website was unexpectedly slower, yeah slower than slowest. At the bottom of the browser it showed connecting to gc.kis.v2.scr.kaspersky-labs.com and it would take more than a minute to load the page.
I googled about connecting to gc.kis.v2.scr.kaspersky-labs.com and found out that it was because of Kaspersky Antivirus Internet Protection enabled that was making it slow.
Not sure though!
