Flash Player Installer appeared on my desktop without warning. Legit or virus?

Question

I've had this happen once before. Last time I just deleted it but I'm afraid it's malware. I can't find the source dmg that's creating this. It looks legit but is there any reason Adobe updates should show up spontaneously on the desktop like this?

Hi,You can verify if it's a legitimate file or not by doing the following:Launch Terminal app (/Applications/Utilities/Teminal.appAt the prompt type: codesign -vvd <Path to Install Adobe Flash Player.app>Easiest way to do this is to drag the APP installer onto the Utilities app after typing codesign -vvdClick EnterLegitimate installers should display the following: Identifier=com.adobe.flashplayer.installmanager Format=app bundle with Mach-O thin (i386) Authority=Developer ID Application: Adobe Systems, Inc. Authority=Developer ID Certification Authority Authority=Apple Root CAYou can also use Disk Utility to see if there is a DMG mounted. If so, you can nmount the DMG using Disk Utility.--Maria
