Norton Security Suite

What is the best antivirus software to use when you're always online?

I am currently using Norton but sadly it will expire soon. I am looking for an antivirus software that can protect my pc longer especially when I'm always online. I have a 496MB ram.

1. AVG from Grisoft is a great one. I've used it for about 5 years now. They have a free version too. http://www.grisoft.com
2. Panda antivirus is the best antivirus It scans your browser while u r online and it also tells u the applications while are trying to access internet without your consent
3. Avast Antivirus free edition http://bestofrest.blogspot.com/2006/12/avast-antivirus_07.html
