Maybe you could recommend something to our friend? Personally, I have been using, recommending, and providing symantec corporate AV solutions to clients for years. I have yet never seen or heard any of my clients catching a virus. Myself included. Symantec AV does hog resources no doubt. I disagree on the detection rate. I believe it is just as good as any other AV solution. However I will say that symantec AV is terrible at cleaning a computer once it is infected and found that using a free version such as AVG does a better job. If you use symantec AV, make sure you schedule "daily" updates because by default its once a week. Stay away from norton internet security if you value resources! My 2 cents.
