Hi Hamdy_hamdy, it has nothing to do with a virus. This message means, as it's said, that you have an old version of flash player, and it's true (you have the version 14.0). So to make disappear this message, you should go on internet and download the last flash player version from adobe website.

Hello, confirm romsdu81 reply, today adobe release the new version for ie and firefox, the 14.0.0.179 version (chrome includes Adobe Flash Player built-in). Probably the plug-in check can't catch it yet !

thank you

No .. this is definitely virus.. because there is no 15.0.0.149 version. and the virus cut off my connect with Facebook website, and redirect links. I tried every thing.. it disappeared for awhile and come back again.

If you get a pop-up message asking to update Firefox or plugins or scanning for malware then such a message is likely a scam and you should never respond to such an alert to avoid getting infected with malware.

• Only update Firefox via "Help > About" or by downloading and installing Firefox from the Mozilla server and never via a pop-up or link on a web page.
• Plugins should only be updated via the plugin itself or by visiting the home page of the plugin.

Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

The problem is I did most of that: • I removed cookies and caches. • I reset and reinstalled all browsers several times. • I made scan with Malwarebytes' Anti-Malware, AdwCleaner, SuperAntispyware, Hitman Pro, and SpyHunter. and I made full scan with Microsoft Security Essential and one more with Norton Internet Security. but every time this pop-up message disappear for awhile and come up again. I tried to find up anyone who complained from the same issue but i get nothing. I don't know how to kick this virus out my PC. and when I tried to connect with Facebook website I get the message page of "Unable to connect: Firefox can't establish a connection to the sever at www.facebook.com" or I get the other page in the picture.

i have the same problem, i think its a virus or something like that, and i did more than you did. i scaned my computer with 6 antiviruses or more. finally i formated all my hard disk. and changed my windos version, but unfortionally , still have the problem!!!!! thats really sucks!!!!!!!

If you can replicate this alert then you can check if you can see any unusual requests in the Network log on the Web Console to see if you can find its origin.
