Another Mac trojan. There’s a program for Macs called MacCinema Installer. The filename is: Flash.Player.Update.v9.19.dmg. Some web sites claim that you need to install it to watch their videos.
When you install it, it adds something to your Mac so that every 5 hours it will try to download malware. So if your Mac becomes infected with malware and you clean it, in 5 hours it’ll download another one. This is pretty common these days.
So if you come across MacCinema don’t install it. And if a web site tells you that you need to install something to watch their videos, don’t trust it (this applies to Mac OS X, Linux, and Windows).
