Intel has invested $16 million in Czech anti-virus company Grisoft.

Grisoft's AVG software is used on 25 million computers around the world, both business and consumer. Intel said it wants to help Grisoft reach a wider audience with its investment.

The proposed $16 million stake in Grisoft - it still has to be approved by the competition council of the Czech Republic - represents Intel's largest investment to date in Central and Eastern Europe. Intel Capital has only invested in five other companies in the region since 1999, including a broadband-over-power lines company in Russia and a telco.

Last year, Intel Capital invested $130 million in emerging companies, with 40 percent of those investments reaching companies outside of the US. The group tries to pick companies that it believes will create or enhance new markets for Intel's products. Last month, Intel Capital announced investments in three Chinese companies from a special fund created to invest in China.
