Back in the day, when I previously used the Norton Anti-Virus suite for my home computer, it gave me the hump. There were a few reasons I got narked with it, the main one being that the hit on system performance was pretty high for an AV suite, and for a chap who liked to play the odd online FPS, it was a bit of a pain. Secondly, once you installed it, it was installed. Every facet of your computers being was wormed into and monitored by Norton, and it felt stifling, and ominous. And if you wanted to get rid of it, you would have been lucky to remove all of its various components and registry entries without a team of Microsoft computer scientists, and a man with a hammer in reserve.
