I have used this free software but biggest disadvantage of this antivirus is non availability in cities also in India, I tried a lot but I didn’t get it. Not only me many of my friends because many people will not trust on online shopping that’s why kasperky.
Norton, quick heal became popular because of availability and also price will be in dollars which makes huge price for common people for ex Kasperky costs 900 rs for 3 users but we don know what is the price of avast this is the biggest problem.
