You will get as many different opinions on this as you will replies. It is usually whatever works for you. Personally I use Norton myself for the AV but I do not like suites of any brand. I prefer to use a seperate program for each thing. There are numerous past discussions on previous pages for your question too if you would like to scroll back through them. You are on page number 1 now and the next most recent threads would be on page 2 and so forth down the line.
