Worryingly unreliable & flaky - when it's bad, it's really bad,
This review is from: Norton Internet Security 2013 - 3 Computers, 1 Year Subscription (PC) (DVD-ROM)
Seems to work fine on some PCs and not on others. Sometimes installs fine and works ok BUT on a small number of PCs (2 out of our 12) it totally screwed the machine up. Typical problems encountered:
* Slowed the machine right down
* Prevented access to programs
* Caused machine to crash / lock up
* Refused to load on boot
* Strange program behaviour / flaky updating
* Strange "stealth" mode
There does not seem any pattern to this. One machine was running XP and the other Win7. One was a Dell and the other an Acer. there are other problems with Norton too:
* Renewing the license will cost twice as much as buying a new license key!!!
* Almost impossible to remove from a machine
* Norton's own uninstall leaves bits of code everywhere
* Norton help desk is very slow and not always helpful
* When it goes badly wrong can destroy ALL your software
To remove this software you will need to use the Win uninstall. That will get rid of the obvious stuff Then you will need to clean out the registry (I use CCleaner to do this). you will find lots of Symantec junk needs to be cleared out. Then go through all files and folders looking for Symantec & Norton. Manually delete all traces. Clear out all history files and when you have done that, install AVG or Bullguard.
Norton has problems with a small but significant number of machines. When it does go wrong it can (at best) stop the machine working properly or, (at worst) wreck the HDD to the point of having to wipe and do a fresh install. Yes, really.
On the basis that, when it goes wrong it does such damage that it's almost impossible to recover easily, I can't recommend Norton 2013. If it's pre-installed, remove it immediately. I have now removed about 20 copies of Norton from machines that have had problems.
