An outside source wrote:Google has slammed an internet security firm's report that suggested malware and viruses placed users of the Android operating system at risk.

Internet security firm McAfee warned on Monday of a growing risk of malware and viruses targeting users of smartphones running on Google's Android operating system.

Chris DiBona, open source program manager for Google, downplayed the report as a self-serving strategy by security companies to scare people into buying their products.

"No major cellphone has a 'virus' problem in the traditional sense that windows and some Mac machines have seen. There have been some little things, but they haven't gotten very far," DiBona wrote in a blog posting.

The warning came just days after Google announced that over 200 million Android devices had now been activated, and as new studies showed that Android devices now account for more than 50% of all smartphones sold worldwide, according to market research firm Gartner.
