How can AVG antivirus be so good and be Free?

I have always had my doubts about it and just recently installed on my wifes computer and it works soo smooth and is great.

How can it still be FREE?

Or better yet how do they stay in business with having a free product on the market?

This is because they accept donations. They do not charge for the service but in turn if you like their product and can even just spare a couple of bucks for their maintenance and upkeep they accept your donation. It's rather ingenious actually. Tons of people donating adds up quick. Especially when the software is so good.

whoever told you AVG was any good LIED the only reason it is free is because it is CRAP just wait till you get a nasty virus or trojan it wont get rid of then you'll see just how good it is
1) It's *not* that good. Avast and Avira are both much better.

2) They and other reputable companies give away less-functional free versions of their paid software as an enticement to buy the better product.
You get what you pay for.
Because it is NOT very good. It virus detection rates are horrible.

Mostly noobs, the naive, the computer illiterate, and children use AVG Free. People of their ilk love AVG because they say it is easy to use and almost never bothers them with any pop-ups or warnings. Of course AVG Free never bothers them, it hardly ever finds any virus to warn them about!
AVG is excellent i I as a matter of fact had a Trojan horses 4 sources it found and destroyed (the free version). AVG is the best there is for free it also finds infected files. AVG can still be free because it makes enough sales through its anti-virus that you can buy, that shows how much people like it.
AVG sucks use Avast or Avira
