This is obviously just my personal opinion, but McAfee is just as worse. These companies are actually helping viruses to spread uninhibitedly. They want people (especially the *vast* majority who buy pre-installed computers from Dell or Compaq/HP) to pay a subscription fee after a certain amount of days. If you don't pay, then you don't get to update your virus definitions. I can't tell you how many computers I've been asked to fix where they were overun with viruses because Norton or McAfee's free trial expired. I've also run into problems a number of times when it came time to uninstall McAfee. I just refuse to use either product.
If you want my recommendation, download AVG Antivirus. I've been using it for about 2 or 3 years now. It's free, constantly updated, and it works.
