Which Antivirus software is better and why?

Norton Antivirus is the most over rated AV of all. Why don't you try NOD32? It's fast, work silently in the background, easy to manage, uses less resources and won't affect your system speed.

Hi swapw07, for paid version, you can try Kaspersky and Symantec antivirus. Both the two does its jobs pretty well. For free version, you could choose AVAST, AVG, and AVIRA. Currently, I am using a free version, which is Avira AntiVir Personal Classic Edition. I have been using this one for over a longer period of time. Since using this software, I have never had encountered any problems at all with regards to the overall function and system performance of my machine. Otherwise, I am very impressed and satisfied with its performance. Its feature is to update regularly and this can be scheduled at your most convenient time. It is very light on resources and does not use a lot of memory. It does not slow down your computer. Overall, it does its jobs pretty well. It detects and deletes rootkits, viruses, worms, etc. Hope this would help. Have a great day and God speed!

i suggest NOD32. it uses less ram, works silently, stops malware and spyware to some extent. above all, unline NAV, it doesnt start communicating with its servers whenever internet is connected. i think it is the best.

Trend Micro's PC-Cillin is good. I especially like the toolbar for Outlook that allows you to block and report spam. I use this at work, but have NAV Internet Security at home. I wish I had stayed with PC-Cillin at home also, but it's done now. I've heard that AVAST is good too. I've used their free download, and it's worked fine for my laptop at home (rarely used).
