At the start of the system, the message says C:users\Rose\ Appdata\Local\Mozilla\MicrosoftHelp\pcwfrqgt.dll I already deleted Mozilla and Firefox

I uninstall Mozilla and Firefox a few months ago and keed get the same message at startup listed above.

Hello

How do you uninstall Mozilla Firefox?

I suggest you to check if Mozilla Firefox is always installed in programs and features:

Perform the steps mentioned below and check if that helps:

Method 1:

Please check if the problem still persists in safe mode too. See the link below for more information about safe mode:

Method 2:

Try to do a Scan SFC (System File Checker). The scan will look bad system files and will attempt to fix them, if possible.

(a) click the Start button.
(b) type: cmd.exe in the search results.
(c) right click the cmd.exe file and select 'run as administrator '.
(d) in the CMD window, type: sfc/scannow and press the Enter key.
(e) restart and see if that solves the problem.
