Have you switched from Norton Antivirus to a different anti-virus software and got better results?

I've heard from a lot of people that Norton Antivirus is a very "heavyweight" antivirus program; it slows down your computer a lot. Has anybody switched anti-virus programs and experienced this while having good protection from viruses?

All my clients are using AVG from http://free.grisoft.com, this has never let any of them down. It is very light weight but very effective.They also have free anti-spyware and anti-rootkit scanners.

just recently we switched TO norton from mcafee and it's working a whole lot better. i guess it depends on people's computers, huh?
i Dont know about heavy weight but the do not update fast enough and virus's get through. i had it on my Vaio and it crashed because noton's/mcafee suck. i discontuned norton's and been with AVG antivirus and it up dates daily and have had it for a year and no problems yet .it scans emails.websites everything on its own then lets you know if any was found the it puts it into a virus vault to contain it and then you just delete them.you can try the free dowload but it dont give you maxium protection so i paid for it on 3 computers.
I hate norton... I switched from norton from mcafee and now my computer is healthier than ever
norton never really impressed me with it's "security". I use a few random ones from download.com that i verified to be safe from spyware
yes.... norton made my computer reallt slow cuz it has alot of memory
Norton SUCKS.
