Best free antivirus.

I use Avast! its the best. Highly reconmend it. Its FREE or you can buy some of the packages. But the free does the scan and ant-virus protection. All youhave to do is register the FREE version and done.

personally i like avg free edition and so i think if you wll stay update your pc will be secure enough but if you want try other security software i think something like avira,avast,kaspersky can be a good choice...even eset nod i think is a good software but i am not really sure that there is available a free version.

For me comodo is the best AV and FW. I would also recommend for you to try out Nod32. that for me is the most balanced AV.

Personally I think that Microsoft Security Essentials is the best.

give a try to Avira antivirus its good too...

ok the best idea if you dont want to purchase a antivirus your 12 months catalogue 1 month Kaspersky Pure 2 kaspersky internet security 3 quick heal 4 norton 5 eset nod 32 internet security 6 kaspersky antivirus 7 eset nod32 antivirus 8 AVG pro 9 Avast 10 quick heal antivirus 11 norton antivirus 12 think yourself change your antivirus software everymonth there a lot of companies and these are arranged in order of priorities When i am saying internet security and antivirus i meant to say the other version/type of antivirus software they are selling Abhishek jain

None of antivirus is better because antivirus have always problem since Window vista and Window 7 was new. If update antivirus - still problem.
