What are these google host entries that keep showing up automatically in my etc/hosts file? I went to edit my /etc/hosts file and found a bunch of entries for google urls that I never put there. When I try to delete it, it just comes back. I tried searching google for it but to no avail. Here is a small sampling of the entries:

It goes on for about 242 lines. Any insight would be appreciated.
216.239.32.20 seems to be a legit Google Inc. IP-address - so nothing to worry about in the first instance: Please check herdprotect.com.

The behavior is probably related to Kaspersky Security. Check this thread at discussions.apple.com.

To prevent the flooding of your hosts file uninstall Kaspersky Security. Then clean it up by editing it with sudo nano /etc/hosts.
