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).
if you do get caught out by this trojan, here are some instructions on how to spot/disable/remove it.
