What antivirus do you use on your computer?

I use Norton antivirus for my pc so that it remains safe and secure from different viruses which keep on attacking it.

i am using the zone alarm i think it is good one and i am using that only i did't face any problem after using these friend.....u can also use these if u want ......

i have unlimited service of the mcaffee internet security suite since i previously worked for MSN. MSN gave us the free mcaffee suite together with our MSN software. the mcaffee internet security is not very good and it eats up a lot of space on my PC. its not that good but its for free so i would take it.

Same here,I used AVG and its free.. So far it upgardes automatically and already block or detected several trojans.
