Symantec researchers are warning of an Android malware campaign that may have affected as many as 5 million users.

"Dubbed 'Android.Counterclank' by Symantec, the malware was packaged in 13 different apps from three different publishers, with titles ranging from 'Sexy Girls Puzzle' to 'Counter Strike Ground Force,'" writes Computerworld's Gregg Keizer. "Many of the infected apps were still available on the Android Market as of 3 p.m. ET Friday."

"Some of the 13 apps that Symantec identified as infected have been on the Android Market for at least a month, according to the revision dates posted on the e-store," Keizer writes.
