I get a message saying my computer has been compromised: what now?

when I was on line, I got a message, supposedly from Microsoft saying that my computer was infected and then it locked up. The message provided a telephone number to call, but I don't know if it is Bogus. I ran a Norton Scan and it says that everything is OK. I can logon with Internet Explorer and everything is fine, but when I try to use Firefox the message pops up and my computer locks up. The only way to get out is to reboot. Then trying to use Firefox results in the same message. Operating System is Windows 10.

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 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.
