Uninstalled Firefox, but still showing in taskmanager and won't force close.

Question

So Firefox didn't quit even in task manager. I shutdown my comp and restarted and then when I closed firefox, it wouldn't open again saying that it was already open and I tried to force quit it in task manager but would not quit. So I uninstalled it and deleted all possible firefox related files, but firefox.exe is still showing in task manager processes and won't quit. Help please.

Answer 1

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.
