As you can see everybody reSponding is saying xyz is best due mainly because that's the flavour of virus protection they have. Most of us only know the product we use. The best one is the one you feel most comfortable using. If you are OK manually updating once a week pick x, if you're happy running and interpreting scans choose y, if you want to use one with no user intervention pick z. They are all much of a muchness, I personally have used Symantec products since Norton DOS days and know their products very well, I have no evidence it is better than another. I never had a problem with viruses, IsAs you can see everybody reponding is saying xyz is best due mainly because that's the flavour of virus protection they have.

Sorry... can't resist. Can a virus package affect your cut & paste functions?
