Links to malware-infested sites and other threats lurk in many Facebook users’ news feeds, according to research from security vendor BitDefender. Among approximately 14,000 Facebook users who installed BitDefender’s Safego security and privacy app, about one in five has malware in his or her news feed. More than 60 percent of the attacks detected by Safego are malicious apps that promise various benefits but install malware when they’re downloaded, BitDefender spokesperson Dan Wire told TechNewsWorld.
