AVG Free Edition good antivirus, and it's free. no popups no spam. its great. much better than (s)norton
Zonealarm is fantasic. Norton is horrible! If you want to protect your computer, uninstall it immediately. AVG free is better for many reasons. First, its FREE. Second, it uses half the system resources as the memory-hungry norton usues. Third, it finds way more viruses than norton. I used to use norton, until I found out about AVG. When I ran AVG for the first time, it found SEVEN viruses, two of which were trojans! Norton is crap...
YES norton is crap worst program i EVER used it crashed on me 3 times in 2 months so i dumped it AVG is lots better and free other good ones are Trend Mirco PC-cillin Internet Security 2005(which i use) and Nod32 is said to be a good one
I use Trend Micro PC-cillin. Not had any trouble yet. Had Norton once, got a virus in under 15 seconds on the internet, in spite of it been up to date! Needless to say I binned it! There are SO many people who have Norton & have problems with it! Only yesterday a work colleague asked what I know about viruses, 'cos he has one, he has Norton installed! I had a guffaw at his expense! AVG is extermely popular with all who use it.
Norton Antivirus is alright, i have been using it for ages, have upgraded to 2005 internet security... my resource for everything software related is about.com, i recommend you visit there, here is its recommendations: http://antivirus.about.com/cs/beforeyoubuy/tp/aatpavwin.htm take a look and see what you think...

I also have Norton AntiVirus 2005 and it's doing ok. Not all AntiVirus is 100% secured -- each has their own good and bad side. And of course you'll also need other free alternatives such as CCleaner, Spybot Search & Destroy, CWShredder, Ad-Aware SE Personal, Microsoft AntiSpyware, AVG Free Edition. I find Sygate Personal Firewall (free) to be a very useful tool, it monitors both outgoing and incoming traffics.
As far as paid for, I have TrendMicro on one computer, and Nod32 on the other. I would say Nod32 is the better of the two, however, TrendMicro is more user friendly. Both update definitions almost daily. I also use MS-Antispyware, Ad-aware SE, and Spybot S&D.
Antivir - A free antivirus, I only found it a few months back and have found that it is defintly better than other free antivirus programs.
