I like the Quick Heal Antivirus because of its great features like very quick scanning. Some times other antivirus may slow down your computers and your work will be pending. But in quick Heal its very fast scanning it will never slow down your computers. Its having the best updates to protect latest virus and removes them permanently. I am using it almost more than 2 years and very happy with the result. Now Quick Heal also launch total security for full protection like internet surfing will be safe.
