[CAESES_watchdog and norton 360 premier]

I updated from 4.0 to 4.1 version and everything seemd ok. what appens is that my antivirus norton 360 premier seems dont like CAESES_watchdog executable, he considers this file highly dangerous and after the scanning this file is put in quarantine. after that I am no more able to unlock CAESES files.

It is dangerous or is only a problem of norton antivirus and in this case what one can do?
