AntiVirus Softwares: choosing the best out of many

firstly any computer user must acknowledge that his the antivirus he is going to use must suit his work, like 
home user 
business user
for home users i recommend the usage of AVG or one can use the AVAST free Antivirus or AVIRA , because these antivirus softwares are light and easy to use, and the home internet users never have to worry about the deterioration of the internet speeds, they are not going to effect the inernet downloading speeds
for business users i recommend KASPERSKY or BITDEFENDER or ESET Nod32, because these softwares make thorough checking and suit the business compatible systems, which have greater configurations when compared to home PCs or laptops or notebooks.
Anyway rating of top 10 antivirus sotwares goes as follows:-

1.) BitDefender

2.)Kaspersky


3.)ESET Nod32


4.) AVG


5.) Norton


6.)Avira


7.) McAfee


8.)Avast


9.) Trend Micro


10.) Webroot
