A warning from Intego said today: a new Trojan program Trojan OSX/flashback. A pretends to be the Flash plugin under OS X for fraud. It disguised as a standard OS X installation program, using Adobe Flash logo as background to attract users’ attention and trust (it is actually very deceptive because Flash has new patches almost every month, users get used to click next to continue).
Fortunately, this malicious software is not the deadly one, users just have to pay extra attention to avoid it. As indicated below, there is a huge difference between the genuine and fake Flash installation program.
