Avira my favorite, It's really awesome. get it here http://www.softspecialist.com/Avira-Antivirus-Free
well you can go for Microsoft official website and you can download ms security essential its totally free for lifetime..........
Before I am using ESET NOD 32 but now I'm using free AVG instead and so far it's good! Just partner it with Malwarebytes and CC Registry Cleaner.
According to me the Microsoft security essentials in the best in free category. How will i rate them? 1) Microsoft Security Essentials 2012 2) Avira Antivirus 3) Avast Free Antivirus 2012 4) Panda Could Antivirus 5) Comodo Antivirus
My opinion no,never .AVAIRA is best in between two. I am using it right now. AVAIRA gives best performance with win-7 ultimate,that I am getting right now. It is easy to maintain and update .
I’m using a free antivirus from Avira and so far I’m satisfied with its performance. It was recommended to me by my former employer. You can search the internet about it if you want to gain more knowledge of its performance.
Quick Heal is the best antivirus and you can download it from its official sites for free and we24support provides best services for this antivirus
