Norton free antivirus is certainly quite effective when it comes to detecting viruses, worms, Trojans and other malicious software codes, but just like any other high-quality product, it too has certain shortcomings. The most common complaint is that Norton slows down the system, so much so that it becomes quite difficult to carry out even the simplest of tasks on your computer. This problem however can be ignored because more often than not the problem is due to the system configuration and not necessarily due to Norton.

In case, you are not too sure as to what exactly is making your system slow down, I would recommend that you delete Norton and see if it makes any difference. If deleting Norton does make a difference to your computer’s speed, then you can keep it that way, but in case you don’t see any significant improvements, I would suggest that you reinstall Norton and keep using it.

The other most common complaint is that Norton disrupts the ‘Automatic Update’ function in Windows based PCs. There is still no reliable evidence that can comprehensively prove this, but since there are just too many people claiming this, you can bet that there is certainly something wrong somewhere. To check for yourself, you just have to delete Norton, restart your computer and see if you are able to get the Automatic Updates. It’s always better to perform your own checks rather than blindly follow what others might be saying or recommending.

To completely delete Norton from your system, you just have to click on Start > Control Panel > Add/Remove Programs > Norton and press on the Change/Remove button. After restarting your computer, you then just have to check whether the targeted problem got resolved on not. If not, then there is no reason as to why you should not reinstall Norton and keep using it for protecting your computer.
