Hello,

That sounds dubious, like something triggered by malware. Can you attach a screenshot of the message?

• How do I create a screenshot of my problem?

Firefox extensions, themes, dictionaries, language packs and search plug-ins aren't executables (.exe) files. Furthermore, such add-ons update automatically by default, without prompting you. You can also update them manually:

1. Click the ≡ Menu Button
2. Click the Add-ons icon.
3. Click the Gear icon near the top right and choose Check for Updates.

Plug-ins are separate software applications. They either have their own updater (e.g. Flash Player), or they're updated along with the application they're bundled with (e.g. Office, iTunes).

Whenever you get a message / popup that software / files need to be updated;

DO NOT USE ANY OF THE PROVIDED LINKS

While this may be a legitimate message, it could also be Malware or a Virus. Any time you want or need to check for upgrades, go to the web site of the True Owner of the program in question. For example, to check out Firefox, go to Mozilla.org. {web link}

You can sent a report to The FBI via their web site Internet Crime Complaint Center (IC3) {web link}

You can also report such a site at; Google Report Phishing Page {web link} which is the same when done while on site by going to Help > Report Web Forgery

Help us safeguard Mozilla’s trademarks by reporting misuse {web link}

In case anything bad got installed along the way, this support article lists tools other Firefox users have found helpful for removing unwanted software: Troubleshoot Firefox issues caused by malware.

Thanks for all your help. It seems to be a malware problem. I ran my Kaspersky security and it picked it up. I have done a clean and all seems well.

Thanks again.
