This is the 2nd time it happens to me! I bought a KIS License in the past, few activations from me, on the same computer, same hardware, just due to formatting it as I do tend to restore back Windows to a previous version when drivers get updates just to ensure optimal performance, so Kaspersky took 15 days to respond to my ticket and give me a manual activation file. Now it happened again with KAV. I didn't even install it more than 6 times and it's already blacklisted!! Never had a problem with multiple installations on any other AV. they take ages to respond!
