I use security software from Symantec / Norton has more than 12 years, stuck with it, 1. From order through to obtain the goods is all OK, but 5 stars, 2. Since I ordered without media, the envelope came only with an installation instruction card and serial number, good for the environment, 5 stars, 3. This time, unfortunately, am a little disappointed, I'm not much surfers because I now have to install the 3rd time Norton Security, because every time after installing that I a few days between the PC by not turn on, etc., as I turn again, leads the Windows system for system recovery, could ever do anything, then of course NORTON SECURITY no longer be seen, 4 stars, usually only 3 stars for it, 4. After you reinstall the PC is running a little slower, stutters every now and then, I have been working for too long with SYMANTEC / NORTON software, this time I'm really disappointed, and I hope that SYMANTEC / NORTON soon have to do something for improvement, go to otherwise IMAGE the drain !!!
