I've used Norton Antivirus in the past,but not anymore.There are far better alternatives.
In my opinion the most reliable pair now,after I've tested a few is:<b>Antivirus</b>:1.<A HREF="http://www.trendmicro.com/en/products/desktop/pc-cillin/evaluate/overview.htm" target="_new"><font color=red><b>Pc-cillin 2005</b></font color=red></A>
I use it without its integrated firewall,as firewall I prefer <A HREF="http://www.zonelabs.com/store/content/catalog/products/sku_list_zap.jsp" target="_new"><b><font color=blue>ZoneAlarm Pro5.5</font color=blue></b></A>
Another very good alternative for those who want a very fast scanning rate is: <A HREF="http://www.eset.com/products/nt.htm" target="_new"><b><font color=blue>Nod32 2.5 Antivirus</font color=blue></b></A>, nod32 has also high detection rate,the lowest memory used & system resources occupattion.
Together with <A HREF="http://agnitum.com/products/outpost/newcontrols.html" target="_new"><b><font color=blue>Outpost Firewall Pro 2.7</font color=blue></b></A> is a good choice.
And at last, but not at least <A HREF="http://www.bitdefender.com/PRODUCT-45-en--BitDefender-8-Professional-Plus.html#" target="_new"><font color=red><b>BitDefender 8 Pro Plus</b></font color=red></A>
BitDefender 8 has a good firewall, <A HREF="http://anti-virus-software-review.toptenreviews.com/" target="_new"><font color=green><i> here is a 2005 review</i></font color=green></A>
These combinations are in my opinion the best available right now, on the market.I say that after I tested Norton Antivirus 2005,AVG pro,McAfee,Avaast,Panda.
Other good firewalls are :
Sygate Personal Firewall Pro 5.5
Kerio Firewall
