We have in the office a pack of 10 licenses for Kaspersky Internet Security (KIS).
Since we suspect a serial number leak, we asked Kaspersky support to generate for us a new key and make the old one invalid. Guess what we are waiting 1 month already for answer, any answer.
The ticket is in status: "Waiting for reply from global support team"
I really hate such crappy support.
Conclusion: Kapspersky support sucks (sux )
