A number of users are reporting that the new Kaspersky AV component in the latest ZoneAlarm Security Suite 7 is broken. And broken in such a way as to leave your system unprotected while appearing to be fully functional.
The problem manifests itself after a successful installation with the AV engine corrupting during a system signature update. Once corrupted it simply fails to offer any protection at all, although the user will be none the wiser of this unless they happen to put their protection to the test.
Something as simple as running an EICAR file past the scanner will do the trick.
