Does Firefox immediately tell you to call when it claims you got a virus
I was surfing google and suddenly got several messages claiming I might have a virus and to call the phone number it provided. Each message had a different phone number so I didn't trust them.

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.
Just to be sure you should 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.
