I was just Browsing the web with Safari and suddenly a Reboot Mac window appeared.
The following is the Error Report:

The problem comes from your Symantec Internet Security Kernel Extension (com.symantec.kext.ips(1.2f28)).

It has generated a Kernel Panic (BSOD on windows).

If this happen again you should contact Symantec to report this issue.

Thanks a lot XianLi

I was just worried as this never happened before... And was trying to figure out How to post a new thread on Apple Discussion Forum from 30 mins !!!
