What is the best free antivirus????internet

If you want a free anti-virus I recommend in order of popularity, but please choose the right one for you (install only one):

1. AVG Free

a. A simple interface (easier to use than Avast! and Avira)

b. Can detect about 82.82% of viruses

Cons: low virus detection

2. Avast!

a. Real-time protection

b. It has an option to delete a virus once found

c. Can detect about 87.46% of viruses.

Cons: Too many icons and confusing user interface

3. Avira AntiVir

a. It can detect malware better than Avast and AVG

b. It's cute umbrella icon

c. Can detect about 94.26% of viruses

Cons: A very sluggish update

Never install Norton anti-virus, it will take over your computer and is almost impossible to completely remove. The best anti-virus available is Kaspersky or NOD32 (recent tests at av-comparatives.org).

AVG Free edition. Downloadable free from www.download.com %26 fully free to use. They also do a free anti spyware program which works great too. I swear by this program, over any of the ones which you pay a subscription for.
AVG Anti Virus Free Edition. I'm surprised you haven't heard of it!
