SecureMac has discovered a new cross-platform trojan horse in the wild that affects Mac OS X, including Snow Leopard (OS X 10.6). The trojan horse, trojan.osx.boonana is spreading through social networking sites, including Facebook, disguised as a video. The trojan is currently appearing as a link in messages on social networking sites. The free removal tool will remove the trojan horse from the affected Mac OS X systems.
