Once upon a time I would have been as anti NAV as the previous reviewer. Working in IT I have seen many a computer system brought to its knees by the system requirements of Norton. However, I read with interest magazine reviews of Norton Internet Security 2009 and thought I would give it a go on one office computer. It's very good you hardly know it's installed on your computer and its very quick to flag up problems and potential problems (like "dodgy" websites...no not that type honest!)
So I would suggest you give it a try, its much better than the old versions and works a treat.
Go on, you know you want to!
I mean it, do not buy this product or anything to do with norton anti-virus!!
We had this installed on our machines for years and we had nothing but problems. It just slowed down the system and somehow managed to let a load of viruses onto our computer and couldn't do anything about them.
Also, when we finally uninstalled the thing it kept causing problems for any other anti-virus software we put on the computer. The only way we managed to reslove the problem was to use Kill-disk to completely wipe the HDD and start all over again.
