I use Norton Internet Security 2009. So far, I have very satisifed with it, I have not encountered any viruses. BTW, I got this particular software because it had the highest review rating.
I use System Suites. It has not let me down in several years and it has tons of great tools to keep your computer working great.
At the moment, I use AVG Free Edition. I don't altogether like it, and I think it does cause me some problems. When I have time, I'll get rid of it and download Avast free version instead, about which I've heard very good things from people I trust and believe. Getting rid of Norton was about the best thing I ever did for my computers.
no antivirus using at this moment i have no data in my pc if my pc lagging then i give a hard kick to cpu then it works fine
Don't use it. And have been virus free for 8 years. When I had it I found that everything took to long to load. And lots of programs did not work. I always had to turn it off anyway. Expecially when playing games because it takes up resources. I am under the believe, maybe misguided, that I am too internet swavy to get a virus. If I do not post for the next week, then you can be sure that its because I got a virus that wiped my computer - the gods punish the overconfident.
