I currently use Windows 7 (64 bit) Professional (all updates installed)
I've had Norton 360 for about 4 months and didn't have this problem until recently.
One day, I noticed that Norton 360 didn't turn on at the startup.
I tried to open Norton 360 manually by double clicking on the desktop icon. Nothing happened.
The support website suggested removing Norton 360 using removal tool and reinstalling it.
So I removed and reinstalled, and 360 worked for a brief moment.
However, when I restarted the computer, it didn't turn on at the startup, and I couldn't open the program manually either.
So I repeated the removal and reinstallation process.
Again, Norton 360 came back on briefly but stopped working when I restarted the computer.
I've now tried "remove and reinstall" 4 times, but same thing happens everytime - restarting the computer renders 360 inoperable.
Can someone please help me with this?

Welcome to Norton Community. Do you have any other Security Program in your computer?
What security Program you had before N360 and how did you removed it?
Type cmd in start->right click on cmd run as administrator->type fltmc hit enter and post the entries in your next post.

My computer came pre-installed with Norton Internet Security (trial version).
When the trial period ended, I decided to upgrade to Norton 360 instead of renewing Norton Internet Security.
I believe the Norton Internet Security was automatically removed when I used Norton 360 installer to install 360.
Below is what I got after typing in the commands as instructed.

I followed all of the above instructions but still no luck.
After I ran LiveUpdate and all updates are downloaded, it gave me a prompt saying "need to restart in order to apply updates."
So I clicked on "restart now" button, computer restarted, but N360 again failed to turn on at the startup, and I can't manually open N360 either.
