Google's alleged dominance in the Android market has led Fairsearch Europe to lodge a complaint against the Internet giant, reported The Guardian.
Google shares a dominating edge among smartphone users with its Android operating system. Android has heavily sidelined Microsoft's Windows 8 OS in Samsung, HTC and Sony.
Fairsearch, a lobby group led by Microsoft, Nokia, Oracle and others, have expressed displeasure of Google's registration with Android OS which enables preinstalled 'Google Maps' and 'YouTube' and other apps on devices.
Thomas Vinje, speaking for the Fairseach group, said: "Google is using its Android mobile operating system as a 'Trojan horse' to deceive partners, monopolise the mobile marketplace, and control consumer data."
"We are asking the commission to move quickly and decisively to protect competition and innovation in this critical market. Failure to act will only embolden Google to repeat its desktop abuses of dominance as consumers increasingly turn to a mobile platform dominated by Google's Android operating system."
Google gave no specific answer on the latest slur. "We continue to work cooperatively with the European Commission," stated Al Verney, spokesman for Google.
The company owns a major share of the mobile market with its Android OS offered free to customers. Microsoft's Windows, on the other hand, have to be purchased.
In the light of the antitrust complaint, Microsoft launched a mocking advertisement campaign called 'Scroogled'.
The ads showing Google in poor taste have been circulating in print, television and online media.
