For the past five years, we had been using Norton but it just seemed to duplicate too much for us and I found my experience with tech support very frustrating and I found them not as helpful. Since working with McAfee, I had the best customer service help ever and we have run McAfee without any problems. Windows XP is another story especially with SP-2, but overall once again, things have been running very smooth for us lately. I was happy to move to McAfee now, not only because I was tired of the hassles we had with Norton, but McAfee does the job for us and is more in our price range. When you aren't working, you have to try and save without compromise. And another thing that in my mind puts Norton to task is how quickly McAfee gives updates for us in terms of what is happening out there - worms, viruses - and how quick they are to fix those issues. I am not sure if we will ever go back to Norton at this point. McAfee is less a drain on our system than Norton ever was. And we are feeling more secure with McAfee than we did with Norton. We did hear horror stories about how McAfee did not protect people from viruses but that has not been our case. We are very happy with our customer service and tech support now and we will be very happy to stick with McAfee. My parents also switched to McAfee and my brother and his wife have used McAfee for years without issues or problems. We had more problems in recent years with Norton and I was totally turned of to their customer service and tech support. They almost seem to be nonexistent at times and by the time they get a hold of you, your issue has been corrected without their help. It got so bad one year that we had to get a refund because we found out after we installed the newer version that we needed to uninstall the previous version. We did get the next version but that was the last we will be dealing with Norton for some time to come. Our experience with Norton was no bed of roses, and in reading what Smart Computing had to say, they would support our view there. They ranked McAfee as the best of the best antivirus programs and firewalls, and to this point, we have far less complaints about McAfee than Norton. I can't see us going back to Norton after how well things have gone for us with McAfee!
