WARNING! Your Flash Player may be out of date.

I keep getting this popup when using Firefox: "WARNING! your flash player may be out of date." I can tell it's phishing and I've never had this problem before. How can I get this to stop when using Firefox? It doesn't happen with IE.

Re: WARNING! Your Flash Player may be out of date.

Do you this alert on pages that use a Flash object or when you start Firefox?

Which Flash player version do you have?


Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

Yes I get the same thing. I think it is adware. I scanned but isn't leaving me.

When I click the link (yes, I was duped), it took me to

http://mt.flashproplayer.com/download5mt.php?src=-&kw=category&lp=4

I get another one too sometimes but cannot find it.

Firefox is almost unusable with this going on.

That page doesn't really look trustful with this footer:

Privacy Policy  l  Terms & Conditions  l  Unistall  l  Contact Us 

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.


Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.

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

You can also do a check for a rootkit infection with TDSSKiller.

Wow what a huge ton of work going through all those malware and rootkit programs to get rid of this thing. Would it help at all to fully uninstall firefox and reinstall? If not, are all the malware programs you recommend at least freeware? Thanks for any information.

Re: WARNING! Your Flash Player may be out of date.

Hi silverlilymt, all of the programs in cor-el's post are free.

Uninstalling and reinstalling Firefox should replace any damaged program files with undamaged ones. But all your add-ons would remain in place, undisturbed, as they are stored with your other personal data such as bookmarks, cookies, saved passwords, and so forth. So usually, reinstalling doesn't fix this kind of problem.

Did this problem just start? Could I suggest disabling ALL nonessential and/or unrecognized extensions on this page -- if in doubt, disable:

orange Firefox button (or Tools menu) > Add-ons > Extensions category

Then restart Firefox using one of the links there and see whether the messages still appear.

Re: WARNING! Your Flash Player may be out of date.

Thank you jscher2000 for your help. My issues started around the time that I made a mistake, about a week or so ago. I fell for a "get free stuff for taking a survey" trick. A momentary lapse in sanity, sorry. I have tried emsisoft malware scanner, and it initially found and quarantined something called Gen%3aTrojan.Heur.Hype.luX%40aGKciof (B) - about which I could find no information. I have since done two deep (and painfully slow) scans with emsisoft, and it now says no threats are detected. But downloader and flash update intrusions continue to happen, only in firefox, not in chrome or IE. Like fettermann, I get one of two different interruptions. I haven't taken a screen snip of the other one, sorry. I have also done the firefox reset to default, which did not help. I think uninstall and reinstall would essentially do the same and likewise not help. I am gratefull to know the programs listed above are freeware. I will invest the time to go through them all, as soon as possible. I do not have very many plugins, and all of them I have had for anywhere from several months to more than a year, and they hadn't caused issues before. (I pretty much think it was the survey scam.) I have seven: silverlight (for netflix), adobe flash, hulu desktop (which I never use but I think was included either in firefox or on my pc at purchase), MS Office 2010, Windows Live Photo Gallery (also a default I think), Google Update and iTunes Application Detector. Hulu is the only one I would disable and consider unneeded. And as it's been there all along and I've never used it, not sure how it could be the source...? I will let the forum know results after I get through the list of malware scanners. Again, thanks very much to all for the info and advice.
