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.
Use McAfee, it is more reliable and has never let me down.

Yes.
I switched from Norton to McAfee and it slowed my computer and I got a virus.
I then went to Office Depot and purchased AVG 7.5 Antivirus and Anti-Spyware.
It doesnt use up your systems resources like other anti virus products.
Its really good.

go for AVG antivirus. its free and takes less memory and system resource as compared to norton.
download free version from http://www.download.com. in the search bar type the keywords, avg and follow instructions

NOD32 is very light and has great protection, but the latest version of Norton Antivirus is lighter compared to the older versions. Plus i like the interface better than anything else.

Yes, I switched from Norton Internet Security with Norton Antivirus, uninstalled it, then installed Windows Live OneCare. It works great! It uses about 1-5% of your system memory. It includes a startup cleaner, printer sharing, and secure Wi-fi.

Yes. Norton is a hog (and it really screwed up my computer when I uninstalled it, so be careful). I now use Prevx and like it much better.

Just done Norton->McAfee, and I can’t tell the difference in performance.

…”Norton” is good, it will get the “job” done but your computer will “crawl”… McAfee puts Norton back in the “stone-age”…

Norton works best on mine

Yes I got AVG backed up by Spyzooka
