AVG Technologies (NYSE:AVG) makes money by providing internet and mobile browser security. The company uses a "freemium" model. This means that users are able to download and use much of the service for free. However, additional services and functionality is given to users though a subscription. Additionally, AVG works with the community to identify and reply to threats as they appear. Some of AVG's services, such as cloud-based storage, sync, and share solutions are not directly linked to internet or mobile security.
AVG's total revenue for the nine months ended in September 2011 was $198M. This resulted in a net income of $100M. The same period in 2010 resulted in $125M in revenue and $48M in net income. The company's single largest expense comes from sales and marketing. 
The company's initial public offering of stock on the NYSE occurred on February 1, 2012. The company offered 8M shares each for $16. This was at the bottom of the $16-$18 initial price range. The deal raised a total of $128M. The lead mangers of the deal were Morgan Stanley (MS), J P Morgan Chase (JPM), and Goldman Sachs Group (GS).
AVG's security software is not associated with any particular platform. However, computer manufactures may bundle their own or one of AVG's competitors security products with the sale of the computer. Microsoft (MSFT) has used this tactic to encourage sales. A similar sales technique could be done by mobile device manufacturers. Without controlling the platform on which it relies, AVG is unable to directly avoid this risk.
