More than a third of all Google Android applications contain some form of malware, according to tests conducted by BT. A security expert for the U.K. telecom service provider said it expects to test apps for other mobile operating systems and find similar results. Wayne Rash, a technology journalist moderating the panel, said he was reviewing a Samsung Galaxy S3 handset and found malware in an Android applications provided by Google. “This is a device considered by some people to be the best smartphone on the market right now,” Rash said. “There’s plenty of anti-malware software available for Android and other mobile operating systems, but companies don’t often insist on using it,” Rash added. The problem is, the issue is not taken as seriously as it should be.
