Yes, I recently had the Norton 360 program on my computer, and it was the best antivirus I have ever seen. It is also the most expensive though. It will block everything that is potentially dangerous from coming onto your computer, and you do not have to worry about nothing.
There are multiple antivirus programs out there. To claim one is better than another is kind of presumptuous. To recommend Norton as the best would be a mistake. There are many other anti-virus programs that are lighter, faster, better definition process, and best of all, free. The best way to avoid virii is to use a different operating system such as Linux.
What the big antivirus companies don't want you to know is that they're basically all the same. As long as you're using a program that's current and accessing regular updates, it doesn't matter what you have on your hard drive. Norton AntiVirus is perhaps not the best, but it is professional.
Norton AntiVirus is not the best antivirus. At the time of its arrival, Norton was the best antivirus program. To date, many more programs have surfaced the market that outperform Norton Antivirus, and some of them are even free. For example, AVG is one of the best antivirus on the market and has exceeded Norton in every aspect and technicality.
Norton is one of the worst antiviruses on the market. It is clunky, bogs down your computer, has too many annoying pop-ups and it costs too much money. There are free virus scans that are much better than the overly priced norton, and you can find them everywhere without trouble.
