Which is the best antivirus for windows computer?

I have used a lot of anti virus programs. Some drastically slowed down my computer and had to remove them and ask for my money back from the sellers. now AVG Anti-Virus I have had no problems

Norton is the best anti virus, Norton Anti-Virus delivers essential protection against all types of malware,

It really depends on your system.... Vipre and Avast are the Top ...
Vipre is best if you're just doing basic and have 2 -4GB of ram with low resource hungry applications. When you get into using AutoCad or Video Rendering , or music production - Avast Free is the best because it does not hog up resources such as Ram while it's running in the background .. whereas others will take up Resources, even Vipre, and you will find out that your applications will run considerably slower.

i think kasoersky is the best antivirus for your computer

Avast & Norton Security !

quick heal antivirus

Avast works well for me.

I used Kaspersky and it good...

Avast is the best for maintaining good pc performance while also providing very good pc virus protection. From my experience Norton slows ones pc down by 30%.

Norton is my best antivirus so far. I am with Norton without any problem yet. My pc is safe with Norton

I am a freelance computer technician for a couple of years now and been using a lot of different antiviruses for my clients computer security..Been using AVG, Avast, Kaspersky, McAfee and others but I end up using Eset Nod32 Antivirus. It is the best so far and been using it for two years now..full edition..I've also been recommended by my client to other people knowing their computer is being configured correctly and security wise. I am glad to introduce to you guys ESET NOD32 ANTIVIRUS..

For me is Symantec Norton Internet Security software. Here is the link for more information.

Avast Antivirus is the best antivirus. it consumes less memory and keeps the speed faster on the other hand keep the computer safe. I am using it from past 5 years now.

It's best to just recycle the PC and get a Mac to run OS.

MS security essentials

I use Ad-Aware and I am satisfied.

I think Quick heel is the best option...

I agree with Ceina Smith, MS Security Essentials is free, effective, light and auto-updates.
